CVE-2025-12116Network attack vector

Stored XSS via unescaped post-title output

Published Feb 19, 2026 · Updated Feb 19, 2026

Stored XSS in Think Up Themes Drift 1.5.0 and earlier allows remote authenticated users to inject scripts through post titles. The theme's options setup renders stored post-title values into HTML without sufficient output escaping, so attacker-supplied markup reaches the page. Contributor-level access is required, and the injected script executes when a user opens an affected page, enabling browser-context data access or actions.
