CVE-2026-109314: Grav Login plugin information disclosure in password-reset page

CVE-2026-109314 · Severity: high · CVSS 7.3 · Published 2026-10-12

The Grav Login plugin is used for managing user authentication on Grav-based websites. A vulnerability in versions before 3.9.9 allows content publishers to trick users into visiting malicious password-reset pages that expose the user's reset token and username. An attacker with publisher privileges can use this exposed token to hijack user accounts, including administrative ones.

Vendors: Getgrav.

Technical details

The Login plugin's getPage() method allows site-authored pages to take precedence over the bundled password-reset page. When a user accesses a password-reset link, the username and reset token are placed into Twig template variables. A publisher-controlled page at the reset route can expose these sensitive variables to the attacker. The vulnerability requires publisher-level privileges and user interaction (opening the reset email link), and enables account takeover via the leaked bearer token.
