GHSA-r5xw-gcgw-hwp5: YesWiki Vulnerable to Reflected XSS via Unescaped `id` Parameter in Bazar Widget HTML AttributesCVE-2026-52774 0 YesWiki versions prior to 4.6.6 with the Bazar extension enabled are vulnerable to a reflected cross-site scripting (XSS) issue. The vulnerability arises because the `id` GET parameter is inserted into HTML attributes without proper escaping, using only `strip_tags()`, which does not neutralize double quotes. This allows attackers to inject arbitrary HTML attributes and JavaScript event handlers, leading to script execution in the victim's browser. The vulnerable endpoint is accessible without authentication or any access control checks, and does not require valid page tags or edit rights. An attacker can craft a URL that, when visited by a victim, triggers the injected script. This vulnerability is classified as CWE-79 and has a moderate severity rating.
