A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: >= 13.0.0, < 13.29.0
Patched in 13.29.0
Vulnerable: < 12.68.0
Patched in 12.68.0
Details
Laravel's built-in TokenGuard, when configured with a standard token-based API guard, may be bypassed to authenticate as an arbitrary existing user without knowledge of their valid API token.
Under certain database configurations (MySQL/MariaDB) an attacker can submit a specially crafted, non-string credential value that is mishandled during the authentication lookup, causing the underlying query to match an unintended user record rather than failing authentication as expected.
An unauthenticated attacker may authenticate as another user without possessing that user's API token, leading to authentication bypass and account takeover on any route protected by the affected guard.
EPSS, exploit probability
Low0.40%
estimated chance of real-world exploitation in the next 30 days, higher than 33.4% of every CVE FIRST.org scores
Refreshed 10/23/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
