dompurify: DOMPurify: Sanitization bypass via hook manipulation

A flaw was found in DOMPurify. An attacker can exploit a vulnerability in how DOMPurify handles its sanitization hooks when default configurations are used. By manipulating the uponSanitizeElement or uponSanitizeAttribute hooks, an attacker can permanently alter the allowed HTML tags and...

DOMPurify: DOMPurify: Cross-site scripting due to state leakage in sanitization.

A flaw was found in DOMPurify. This vulnerability allows a remote attacker to perform cross-site scripting XSS by exploiting a state leakage issue. Specifically, function predicates used for adding attributes or tags during sanitization can persist across multiple calls to the sanitize function...

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...

dompurify: DOMPurify: Cross-Site Scripting vulnerability allows arbitrary code execution

A flaw was found in DOMPurify. This vulnerability, a type of Cross-Site Scripting XSS, occurs when HTML that has been sanitized is reinserted into specific parsing contexts using innerHTML with certain HTML elements like script or iframe. An attacker can craft malicious input that, during...

dompurify: DOMPurify: Cross-site scripting vulnerability via attacker-controlled nodeName

A flaw was found in DOMPurify. This cross-site scripting XSS vulnerability exists in INPLACE mode, where the software trusts attacker-controlled nodeName on live non-form nodes. A remote attacker can supply hostile live Document Object Model DOM objects with script children. These scripts can...

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...

dompurify: DOMPurify: Cross-Site Scripting (XSS) via prototype pollution in USE_PROFILES mode

A flaw was found in DOMPurify. This prototype pollution vulnerability, specifically when operating in USEPROFILES mode, allows a remote attacker to bypass attribute filtering. By manipulating Array.prototype properties, an attacker can cause DOMPurify to accept event handlers as allowed attribute...

dompurify: DOMPurify: Client-side arbitrary code execution due to improper Trusted Types policy reset

A flaw was found in DOMPurify where the clearConfig function does not properly reset the retained Trusted Types policy. This can lead to a DOMPurify instance, when reused across different security contexts, remaining bound to a previously supplied and potentially unsafe policy. An attacker could...

dompurify: DOMPurify: Cross-site scripting vulnerability allows code execution

A flaw was found in DOMPurify, a tool designed to sanitize HTML, MathML, and SVG to prevent cross-site scripting XSS attacks. When performing in-place sanitization, DOMPurify could fail to properly process content within shadow DOM elements attached to a .content. This oversight allows an attacke...

CVE-2026-73426

Trix is a what-you-see-is-what-you-get rich text editor for everyday writing. Prior to 2.1.17, Trix is vulnerable to cross-site scripting when a data-trix-serialized-attributes attribute bypasses the DOMPurify sanitizer. An attacker can craft HTML containing a data-trix-serialized-attributes...

CVE-2026-73426

Trix (a WYSIWYG rich text editor by Basecamp) versions prior to 2.1.17 are vulnerable to stored cross-site scripting (XSS) . The root cause is a data-trix-serialized-attributes attribute that bypasses the DOMPurify sanitizer. An attacker can craft HTML containing this attribute with a malicious p...

CVE-2026-73426 Trix: Stored XSS vulnerability through serialized attributes

Trix is a what-you-see-is-what-you-get rich text editor for everyday writing. Prior to 2.1.17, Trix is vulnerable to cross-site scripting when a data-trix-serialized-attributes attribute bypasses the DOMPurify sanitizer. An attacker can craft HTML containing a data-trix-serialized-attributes...

CVE-2026-75838

DOMPurify before 3.4.13 contains a cross-site scripting vulnerability in INPLACE sanitization where element-removal hooks fail to neutralize detached subtrees. Attackers can supply HTML with event handlers on descendant elements that execute after sanitization completes, even though the returned...
