CVE-2026-15253Network attack vector

Stored XSS via unescaped attachment title

Published Aug 19, 2026 · Updated Aug 19, 2026

Stored XSS in Easy Media Replace through 0.2.0 allows remote authenticated users to execute scripts via a crafted attachment title. The plugin renders the attachment title into an HTML attribute in the media library list view without sanitization or output escaping. Exploitation requires Author-level access or higher to store the title and a higher-privileged user to open the media library, after which attacker-supplied JavaScript runs in that user's browser.
