CVE-2026-85172 n8n before 2.34.1 SSRF via Request Helper URI Validation Bypass

n8n versions before 2.34.1 contain a server-side request forgery vulnerability in the legacy request helper function exposed to Code and Function nodes. The validation logic checks the uri property for SSRF safety while the underlying HTTP client uses the url property when both are present,...

CVE-2026-85172

n8n versions before 2.34.1 contain a server-side request forgery (SSRF) vulnerability in the legacy request helper function exposed to Code and Function nodes. The root cause is a mismatch between validation and execution: the SSRF check inspects the uri property, while the underlying HTTP client...

BIT-KEYCLOAK-2026-9086 Keycloak: keycloak: cross-site scripting (xss) via case-insensitive uri validation bypass

A flaw was found in Keycloak. A remote attacker with administrative privileges, specifically those with manage-client permission or access to client registration endpoints, could bypass client Uniform Resource Identifier URI validation. This is achieved by registering a malicious client with a...

URI Validation Bypass

http4k-security-digest is vulnerable to URI Validation Bypass. The vulnerability is due to the client not validating the uri parameter in the Digest authentication response against the actual request URL, which allows an attacker to replay a captured authentication response against other URLs...

dompurify: DOMPurify: URI validation bypass leads to cross-site scripting

A flaw was found in DOMPurify. An attacker can bypass URI validation by providing a specially crafted predicate function via EXTRAELEMENTHANDLING.attributeCheck. This allows unsafe protocols, such as javascript:, to persist after sanitization, potentially leading to DOM-based cross-site scripting...

GHSA-CJMM-F4JC-QW8R DOMPurify ADD_ATTR predicate skips URI validation

Summary DOMPurify allows ADDATTR to be provided as a predicate function via EXTRAELEMENTHANDLING.attributeCheck. When the predicate returns true, isValidAttribute short-circuits the attribute check before URI-safe validation runs. An attacker who supplies a predicate that accepts specific...

Permissive List of Allowed Inputs

Overview org.webjars.npm:dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG. Affected versions of this package are vulnerable to Permissive List of Allowed Inputs in the ADDATTR predicate function via EXTRAELEMENTHANDLING.attributeCheck. An attacker can inject and execute malicious...
