CVE-2026-24354Network attack vector

Contributor-level script execution in privileged browsers

Published Jan 22, 2026 · Updated Jan 22, 2026

DOM-based cross-site scripting in PenciDesign Penci Shortcodes & Performance 6.1 and earlier allows remote authenticated users to run scripts. The public advisory does not identify the affected client-side routine, DOM source, sink, or incorrect input-handling operation. Contributor or Developer access can initiate the flaw, but successful exploitation requires a privileged user to act on attacker-controlled content, executing the payload in that user's browser.
