CVE-2026-94379
MISP: HTTP Method Bypass of Login Security Controls (Bruteforce Protection and Email OTP)
02 Description
MISP: HTTP Method Bypass of Login Security Controls (Bruteforce Protection and Email OTP)
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.57% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 47.3% of scored records. A rank, not a probability.
- NVD base score
- 6.9 (CVSS v4.0), scored by the NVD independently of the CNA.
- NVD CVSS vector

- NVD analysis status
- Deferred. NVD last modified this record on 2026-09-21.
- Red Hat severity
- No Red Hat rating. Red Hat rates the CVEs that affect its products.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation
The fix replaces the allowlist-style HTTP method checks (is POST or PUT) with a denylist approach (is NOT GET) in all three security-critical branches of the login() function. This ensures that every non-GET HTTP method—regardless of whether it is POST, PUT, PATCH, DELETE, HEAD, OPTIONS, or any other—triggers the bruteforce protection, email OTP verification, and login-failure logging code paths, closing the method-based bypass.
