CVE-2026-109321

Name of the Vulnerable Software and Affected Versions Grav Login OAuth plugin (grav-plugin-login-oauth) versions prior to 1.4.3

Description The plugin provisions OAuth accounts as standard users using a deterministic <provider>.<id> username and an unsalted MD5 hash of the provider identifier as the password. Because password login remains enabled, unauthenticated remote attackers who obtain or guess a provider identifier can recreate these credentials to log in and potentially gain administrative control of privileged accounts.

Recommendations Update Grav Login OAuth plugin (grav-plugin-login-oauth) to version 1.4.3 or later.
