SUSE CVE-2026-65903
DOMPurify before 3.4.0 contains a logic error in the ADDTAGS function where short-circuit evaluation allows forbidden tags to bypass FORBIDTAGS restrictions. Attackers can craft input containing tags listed in FORBIDTAGS that are also added via ADDTAGS function, causing them to be retained in...
DOMPurify Code Execution
The vulnerability of the FORBIDTAGS function in the JavaScript library for secure cleaning and protection of HTML code by DOMPurify is related to the lack of measures taken to protect the structure of web pages. Exploiting this vulnerability could allow a remote attacker to execute arbitrary code...
