Stored XSS via unescaped shared-page titles
Published Feb 10, 2026 · Updated Feb 10, 2026
Stored XSS in Docmost before 0.25.0 allows remote authenticated users to execute JavaScript when a user opens a public share link. ShareSeoController reads a stored page title and interpolates it unescaped into title, Open Graph, and Twitter meta elements. Exploitation requires page-editing access, public sharing, and a user opening the link; the resulting script can redirect the user or present a fake login form.
