DOMPurify before 3.4.0 contains a logic error in the ADD_TAGS function where short-circuit evaluation allows forbidden tags to bypass FORBID_TAGS restrictions. Attackers can craft input containing tags listed in FORBID_TAGS that are also added via ADD_TAGS function, causing them to be retained in sanitized output.

A flaw was found in DOMPurify. A logic error in the ADD_TAGS function allows an attacker to bypass security restrictions. By crafting specific input, an attacker can cause tags that should be removed to remain in the sanitized output. This could lead to the injection of malicious content, potentially compromising the integrity of web pages.
