CVE-2026-56785

Threat Intelligence NVD CVE 危険度: high 緊急度: high

FlatPress contains a stored cross-site scripting vulnerability in comment and contact forms where name, URL, and email fields are rendered without proper output encoding in Smarty templates. Attackers can inject arbitrary HTML and JavaScript through these fields to execute malicious scripts in browsers of viewers including administrators, or bypass URL scheme validation to inject javascript: or data: URIs.

CVE-2026-54588

Threat Intelligence NVD CVE 危険度: high 緊急度: high

Poweradmin is a web-based DNS administration tool for PowerDNS server. Versions prior to 4.2.4 and 4.3.3 use the attacker-controlled `HTTP_HOST` request header as the authoritative source for building callback URLs in its OIDC, SAML, and logout authentication flows without any validation. An unauthenticated attacker can poison the `redirect_uri` sent to the Identity Provider, causing the IdP to redirect the victim's authorization code to an attacker-controlled server - resulting in full account takeover with no credentials required. Versions 4.2.4 and 4.3.3 patch the issue.

CVE-2026-48493

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

Snipe-IT is an IT asset/license management system. In versions prior to 8.6.0, a user with only users.edit can send a PATCH to /api/v1/users/{their_own_id} and grant themselves any permission except admin and superuser — for example `assets.view`, `assets.create`, `reports.view`, import, etc. The issue is patched in version 8.6.0.

CVE-2026-47693

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

Poweradmin is a web-based DNS administration tool for PowerDNS server. Versions prior to 4.2.4 and 4.3.3 are vulnerable to CSV Injection (Formula Injection) in its log export functionality. User-controlled data — specifically the username field — is written to exported CSV files without sanitizing formula trigger characters (=, +, -, @). When an administrator exports activity logs and opens the resulting CSV in a spreadsheet application (Microsoft Excel, LibreOffice Calc, Google Sheets), any formula stored in a username is executed by the application. This can be used for phishing attacks against administrators or data exfiltration. Versions 4.2.4 and 4.3.3 patch the issue.

CVE-2026-12164

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

Fortra File Integrity Monitoring (FIM), formerly Tripwire Enterprise, versions prior to 9.4.0 may assign incorrect or elevated effective permissions to users created by the tetool import command while FIM is running, particularly when the import also creates or changes roles or role-permission relationships.

CVE-2026-12163

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

Fortra File Integrity Monitoring (FIM), formerly Tripwire Enterprise, versions prior to 9.4.0.1 contain a stored cross-site scripting (XSS) vulnerability in the Asset View UI component. An authenticated user with sufficient privileges to create or modify affected node or database configuration fields could store script content that may be rendered as HTML instead of safely escaped text when the affected Asset View UI content is displayed.

CVE-2026-11972

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

When using the "tarfile" module with a file opened in "streaming mode" (mode="r|") the tarfile module did not properly handle EOF, making archive parsing take exponentially longer.

CVE-2026-54518

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, UnwrappedPropertyHandler.processUnwrappedCreatorProperties() replays buffered JSON into creator parameters but never consults prop.visibleInView(activeView). The normal property-based creator path gates creator properties on the active view, but this unwrapped-creator replay path bypasses that check, so a constructor parameter annotated with both @JsonView(AdminView.class) and @JsonUnwrapped is populated from attacker JSON even when a more restrictive view is active. This vulnerability is fixed in 2.21.4 and 3.1.4.

CVE-2026-9073

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

A flaw was found in foreman-mcp-server. This component utilizes two distinct logging mechanisms that can expose sensitive session and authentication data. One mechanism logs session identifiers, which are treated as authentication credentials, at an informational level. The other, when debug logging is enabled, incompletely sanitizes HTTP request headers, leading to the cleartext logging of sensitive information such as authorization tokens and API keys. This vulnerability can result in a confidentiality breach, as sensitive authentication data is persisted in plain text within container logs, increasing the risk if logs are forwarded to a centralized platform.

CVE-2026-56120

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority as it's a duplicate of CVE-2026-56784.

CVE-2026-54517

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, in BeanDeserializer._deserializeUsingPropertyBased, the active-view (@JsonView) filter was applied only to creator properties; the regular property-buffering branch performed no prop.visibleInView(activeView) check. A change making SetterlessProperty.isMerging() return true routed setterless Collection/Map properties through this unguarded path, so a setterless collection annotated with a restricted @JsonView is populated from attacker JSON even when the active view excludes it. This vulnerability is fixed in 2.21.4 and 3.1.4.

CVE-2026-54516

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, POJOPropertiesCollector._renameProperties() allows a property with @JsonProperty("renamed") on the getter and @JsonIgnore on the setter to be renamed rather than dropped. With MapperFeature.INFER_PROPERTY_MUTATORS enabled (default), the private backing field is retained; during deserialization BeanDeserializerFactory.addBeanProps() sees hasField()==true, builds a FieldProperty, and makes the backing field writable. An attacker supplying the renamed JSON key writes the backing field directly, bypassing the @JsonIgnore on the setter. This vulnerability is fixed in 3.1.4.

CVE-2026-54515

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.8.0 until 2.18.9, 2.21.5, and 3.1.4, in BeanDeserializerBase.createContextual(), per-property @JsonIgnoreProperties exclusions are applied by _handleByNameInclusion(), producing a contextual deserializer whose BeanPropertyMap has the ignored properties removed. The subsequent per-property case-insensitivity block (triggered by @JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) rebuilds from this._beanProperties (the original, unfiltered map) instead of contextual._beanProperties, then overwrites the filtered map — restoring every property _handleByNameInclusion had just removed. The ignored property becomes writable again. This vulnerability is fixed in 2.18.9, 2.21.5, and 3.1.4.

CVE-2026-54514

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.0.0 until 2.18.8, 2.21.4, and 3.1.4, JDKFromStringDeserializer constructed InetSocketAddress with new InetSocketAddress(host, port), which performs eager DNS name resolution for hostname inputs at deserialization time. An application that binds untrusted JSON into a type containing an InetSocketAddress field issues an attacker-chosen DNS query during readValue, before any application-level validation or connect logic. The fix uses InetSocketAddress.createUnresolved(host, port), deferring DNS to an explicit connect. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.

CVE-2026-54513

Threat Intelligence NVD CVE 危険度: high 緊急度: high

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() allowlists any array type based only on clazz.isArray(), without validating the array's component (element) type against the configured allowlist. A PTV built with allowIfSubTypeIsArray() plus an explicit concrete-type allowlist therefore still permits EvilType[] even though EvilType is not allowlisted. When Jackson deserializes the elements and no per-element type IDs are present, it instantiates the component type directly with no further PTV check, bypassing the allowlist. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.

CVE-2026-54512

Threat Intelligence NVD CVE 危険度: high 緊急度: high

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, jackson-databind's PolymorphicTypeValidator (PTV) is the primary safety mechanism guarding polymorphic deserialization. When polymorphic typing is enabled and a type identifier contains generic parameters (i.e. the type ID string contains <), DatabindContext._resolveAndValidateGeneric() validates only the raw container class name (the substring before <) against the configured PTV. If the container type is approved, the method parses the full canonical type string via TypeFactory.constructFromCanonical() and returns the fully parameterized type without ever validating the nested type arguments against the PTV. The nested type arguments are then resolved, instantiated, and populated as beans during deserialization. An attacker who controls the type ID can therefore place a denied class as a generic type parameter of an allowed container — for example java.util.ArrayList<com.evil.Gadget> when only java.util.ArrayList is allow-listed. The container passes the PTV check; com.evil.Gadget is loaded via Class.forName(name, true, loader), instantiated, and its properties are set from attacker-controlled JSON. This completely bypasses an explicitly configured PTV allow-list. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.

CVE-2026-53931

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the spreadsheet-import endpoint axiosRequestMake could be used as a generic HTTP proxy. Before the fix it was reachable unauthenticated, and its URL-extension allowlist was a regex tested against the full URL string, so URLs whose query string ended in .csv satisfies the gate even though the underlying request is for another file. This vulnerability is fixed in 2026.05.1.

CVE-2026-53930

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the base-migration endpoint accepted a caller-supplied URL that the migration worker dereferenced without enforcing protocol or destination, allowing scheme abuse (file:, ftp:, etc.) and probing of internal HTTP destinations. This vulnerability is fixed in 2026.05.1.

CVE-2026-53929

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, with NC_SECURE_ATTACHMENTS=true, an authenticated uploader could deliver .html or .svg attachments that the browser rendered inline from the NocoDB origin instead of forcing a download. The signed attachment handler stored response-header overrides under PascalCase keys (ResponseContentDisposition, ResponseContentType) while the controller that served the file read them under lowercase-hyphen names (response-content-disposition). The mismatch dropped the Content-Disposition: attachment header, leaving Express to auto-render .html, .svg, and similar inline. This vulnerability is fixed in 2026.05.1.

CVE-2026-53928

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, a stolen refresh token survived a password-forgot flow and could be used to mint fresh JWTs even after the user reset their password. passwordChange and passwordReset deleted the user's refresh tokens, but passwordForgot only rotated token_version and revoked OAuth tokens — it did not call UserRefreshToken.deleteAllUserToken(user.id). An attacker holding a captured refresh cookie could still exchange it for a new access token after the victim triggered the recovery flow. This vulnerability is fixed in 2026.05.1.

CVE-2026-53927

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the spreadsheet-fetch endpoint (axiosRequestMake) accepted URLs whose path contained a permitted extension anywhere in the string, and applied a hand-rolled regex blocklist that omitted 127.0.0.0/8 and 169.254.0.0/16, allowing the cloud-metadata endpoint to be reached with a crafted URL This vulnerability is fixed in 2026.05.1.

CVE-2026-53926

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, revokeAllOAuthTokensByUser in the users service is an empty stub being called from passwordChange, passwordForgot, and passwordReset. OAuth access and refresh tokens were not revoked when the user changed, reset, or recovered their password, leaving an attacker-issued OAuth grant valid after the user believed they had locked the attacker out. This vulnerability is fixed in 2026.05.1.

CVE-2026-50193

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply nested JSON if (and only if) the service reads deeply nested (1000s of levels) JSON as JsonNode (ObjectMapper.readTree()) and writes out same (or modifided) node using JsonNode.toString(). This can consume significant amount of resources with concurrent relatively small requests (1000 nested arrays is 2kB). This vulnerability is fixed in 2.14.0.

CVE-2026-47388

Threat Intelligence NVD CVE 危険度: medium 緊急度: medium

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, a low-privilege MCP token holder with knowledge of an attachment path could read any file in shared storage, including attachments belonging to other bases and workspaces, because the MCP readAttachment tool did not verify the file's ownership. This vulnerability is fixed in 2026.05.1.
