CVE-2026-52772
YesWiki has stored XSS in Bazar form-field templates via unescaped field.label / field.hint (|raw('html'))
Impact
YesWiki is a wiki system written in PHP. Prior to version 4.6.6, Bazar form-field templates still apply |raw('html') to field.label / field.hint in attribute and label-body contexts, resulting stored XSS in form renders. This issue has been patched in version 4.6.6.
