Contributor-level stored XSS via Title Block output
Published Sep 22, 2025 · Updated May 13, 2026
Stored XSS in BdThemes ZoloBlocks 2.3.12 and earlier allows remote authenticated users to execute scripts through crafted Title Block content. The Title Block accepts crafted content without sufficient input sanitization and renders it without adequate output escaping. Contributor access is required to store the payload, and successful exploitation requires another user to render the affected block in a browser.
