Stored XSS via case-sensitive protocol blocklist
Published Aug 15, 2024 · Updated Aug 16, 2024
Stored XSS in Ibexa RichText Field Type before 4.6.10 allows remote authenticated users to execute scripts through crafted links. The RichText link validator uses a case-sensitive blocklist for javascript: and vbscript: URIs, allowing uppercase or unlisted executable schemes; the same defect affects eZ Platform RichText Extension before 3.3.40. RichText content-editing permission, typically Editor role or higher, is required, and stored payloads execute in pages that render the content.
