Name of the Vulnerable Software and Affected Versions Valibot versions prior to 1.4.2 Description Valibot can throw a TypeError within its flatten helper when validation issues contain object keys controlled by an attacker that collide with inherited Object.prototype properties, such as toString,...

Prototype Pollution

Overview Affected versions of this package are vulnerable to Prototype Pollution in the lookup function when handling HTTP/2 requests. An attacker can cause the application to crash by sending specially crafted HTTP method values that exploit inherited object properties, leading to a denial of...

CVE-2026-65913

DOMPurify before 3.3.2 contains a prototype pollution vulnerability in USEPROFILES mode that allows attackers to bypass attribute filtering by polluting Array.prototype properties. Attackers can set Array.prototype properties like onclick to true, causing DOMPurify to accept event handlers as...

CVE-2026-65913 DOMPurify before 3.3.2 Prototype Pollution via USE_PROFILES

DOMPurify before 3.3.2 contains a prototype pollution vulnerability in USEPROFILES mode that allows attackers to bypass attribute filtering by polluting Array.prototype properties. Attackers can set Array.prototype properties like onclick to true, causing DOMPurify to accept event handlers as...

CVE-2026-65913

DOMPurify prior to 3.3.2 is affected by a prototype pollution vulnerability in USE_PROFILES mode. An attacker can pollute Array.prototype properties (e.g., onclick) to bypass attribute filtering, causing DOMPurify to treat event handler attributes as allowed. This enables DOM-based XSS when sanit...

CVE-2026-65902 DOMPurify before 3.4.7 Hook Mutation Pollution via allowedTags

DOMPurify before 3.4.7 affected versions = 3.4.5 passes direct references to the module-level DEFAULTALLOWEDTAGS and DEFAULTALLOWEDATTR sets to the uponSanitizeElement and uponSanitizeAttribute hooks via data.allowedTags / data.allowedAttributes when sanitize is called without an explicit...

CVE-2026-65898

DOMPurify before 3.4.11 is affected. The vulnerability arises when setConfig() is used with an uponSanitizeAttribute hook and the ALLOWED_ATTR allowlist isn’t cloned, allowing the hook to permanently mutate the shared allowlist. An attacker can register a hook that conditionally permits dangerous...

Prototype Pollution

Overview n8n-core is a Core functionality of n8n Affected versions of this package are vulnerable to Prototype Pollution in the expression engine. An attacker can cause the application to become unresponsive or crash by manipulating array-element access to obtain a reference to a host built-in an...

GHSA-HX4H-VR3M-45VH n8n: Prototype Pollution via VM Expression Engine Sandbox Escape Leads to Denial of Service

Impact An authenticated user able to create or edit a workflow expression could abuse the expression engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process, leading to a denial of service. Both self-hosted and cloud instances runni...

Prototype Pollution

Overview n8n-nodes-base is a Base nodes of n8n Affected versions of this package are vulnerable to Prototype Pollution via the Edit Fields Set process when output fields are assigned using dot-notation path setters without restricting field names. An attacker can corrupt a shared global in the ma...

GHSA-XWX6-JJHV-84P8 n8n: Prototype Pollution via Dot-Notation Field Names Leads To Instance-Wide Denial of Service

Impact The Edit Fields Set node assigned output fields through a dot-notation path setter without restricting the field name, so an authenticated user could name a field after an inherited built-in method path and corrupt a shared global in the main Node.js process. Because that global was used o...

n8n: Prototype Pollution via Workflow Credentials Leads to Unauthenticated User and Project Enumeration...

GHSA-75QM-GP28-RCQ9 n8n: Prototype Pollution via Workflow Credentials Leads to Unauthenticated User and Project Enumeration

Impact An authenticated user with the default workflow:create permission could pollute Object.prototype through a crafted workflow saved, updated, or imported via the workflow API. This can be leveraged to bypass authentication, allowing unauthenticated requests to be treated as a privileged user...
