CVE-2026-114509 — Laravel TokenGuard authentication bypass through non-string API credentials

Laravel is a web application framework. Prior to 12.68.0 and 13.29.0, TokenGuard configured as a standard token-based API guard does not reject a crafted non-string credential. Under affected MySQL or MariaDB configurations, the authentication lookup can match an unintended existing user, allowing an unauthenticated attacker to bypass authentication and take over an account on routes protected by TokenGuard. This issue is fixed in versions 12.68.0 and 13.29.0.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.8% (30-day exploitation probability)+8
  • Technical severity (critical)+10

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

  • Composer Laravel/framework: fixed in version 12.68.0 — github.com (GitHub Security Advisories)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Laravel Framework, Composer Laravel/framework).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. Apply the fixed version or the patch documented under Remediation.
  4. Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

  • Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
  • Review authentication logs: logins without MFA, anomalous sessions and recently created accounts.

What should defenders know first?

CVE-2026-114509 is "Laravel TokenGuard authentication bypass through non-string API credentials", rated Critical. It affects Framework (Laravel); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 9.2 describes technical severity. EPSS 0.78% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
