dompurify: DOMPurify: Cross-site scripting via permanent attribute allowlist pollution

A flaw was found in DOMPurify. When the setConfig function is used with an uponSanitizeAttribute hook, the ALLOWEDATTR allowlist is not properly cloned. This allows an attacker to register a hook that can permanently modify the shared allowlist, enabling the conditional allowance of dangerous...

Stored Cross-Site Scripting (XSS)

DOMPurify is vulnerable to stored cross-site scripting XSS. The vulnerability is due to the setConfig API bypassing the parseConfig clone protection, allowing an uponSanitizeAttribute hook to permanently modify the shared attribute allowlist, which allows an attacker to persistently enable...

DOMPurify: Permanent `ALLOWED_ATTR` pollution via `setConfig()` bypassing the hook clone-guard (incomplete fix of the 3.4.7 hook-pollution patch)

Summary DOMPurify 3.4.7 shipped a security fix "permanent hook pollution" that makes a registered uponSanitizeAttribute hook's mutation of data.allowedAttributes non-persistent — so allowing an attribute for one element does not leak into later sanitize calls. The fix clones ALLOWEDATTR inside...
