CVE-2022-50949Public exploitNetwork attack vector

Stored XSS via unsanitized video option fields

Published May 10, 2026 · Updated May 10, 2026

Stored XSS in A-J-Evolution Videos sync PDF 1.7.4 allows remote authenticated users to execute JavaScript in administrators' browsers. The plugin options panel stores mov, pdf, mp4, webm, and ogg field values without sanitizing dangerous attribute syntax, then renders them with video settings. Access to the plugin options panel is required to save the payload, and an administrator's later interaction triggers script execution in that browser session.
