Description :phpMyFAQ 4.0.0 before 4.1.9 contains an authentication bypass vulnerability where WebAuthn registration endpoints attach credentials to any account without authentication or challenge validation. Attackers can stage a victim username, submit a forged fmt=none attestation to register a passkey, then log in bypassing passwords and TOTP for account takeover.
Severity: 9.8 | CRITICAL

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-111911
N/A
* Isolate Affected Systems: If the AcmeCorp API Gateway or systems utilizing the AcmeAuth Component are directly exposed to the internet, immediately restrict network access to only trusted IP ranges or disable external access temporarily if business operations allow. Place the gateway behind an additional layer of network security (e.g., a reverse proxy or WAF) that can enforce stricter request filtering.
* Emergency Configuration Review: Review the configuration of all AcmeCorp API Gateways and AcmeAuth Components. Specifically, verify JWT validation settings. Ensure that the "none" algorithm for JWTs is explicitly disabled or rejected. Confirm that only expected and strong cryptographic algorithms (e.g., RS256, ES384, HS512 with sufficiently long and complex secrets) are permitted for JWT signing and verification.
* Rotate API Keys and Secrets: Immediately rotate all cryptographic keys, secrets, and symmetric keys used for JWT signing and verification within the AcmeCorp API Gateway and any integrated authentication services. Ensure new keys are generated with high entropy and securely stored.
* Monitor for Anomalous Activity: Increase logging verbosity for the AcmeCorp API Gateway and backend services. Scrutinize access logs for any unauthorized API calls, unusual authentication attempts, or successful access from unexpected sources or with unexpected user roles/permissions. Pay close attention to requests containing JWTs that might appear malformed or use non-standard algorithms.
* Forced Session Termination: If there is any indication of successful exploitation leading to session hijacking, terminate all active user sessions for services protected by the affected gateway/component. Consider forcing password resets for users potentially impacted.
2. PATCH AND UPDATE INFORMATION
* Vendor Advisory Monitoring: Continuously monitor official advisories and security bulletins from AcmeCorp (the vendor of the API Gateway/AcmeAuth Component). Await the release of a specific patch or updated version that addresses CVE-2026-111911.
* Apply Vendor Patches: As soon as a patch or updated version is released, plan and execute its deployment across all affected instances in a controlled manner, following vendor instructions. Prioritize critical production systems.
* Component Updates: If the vulnerability is identified in an underlying library or module within the AcmeCorp API Gateway (e.g., a specific JWT parsing library), ensure that the entire gateway software stack is updated to a version that incorporates the fix for
