CVE-2026-10611 — MISP: OTP bypass when LDAP mixed-auth and OTP enforcement are both enabled
Part of run 2026-06-04-51b23ffa (intel · Claude Opus 4.8)
CIRCL disclosed an authentication-bypass in MISP where, with LdapAuth.mixedAuth=true and Security.require_otp=true, the user session is established in the login beforeFilter() phase before the OTP challenge is enforced — so an attacker holding valid LDAP credentials authenticates and gets a valid session without completing TOTP/HOTP/email OTP (GitHub Security Advisory GHSA-679G-PP8V-JVG4, 2026-06-02 · BSI CERT-Bund WID-SEC-2026-1778, 2026-06-02). MISP is the dominant open-source TI-sharing platform across EU/CH national CERTs and ISACs, so the blast radius is full instance access including TLP:AMBER/RED shared data and stored API keys. Fix is commit 39b3cb15 per the GitHub advisory; interim, drop one of the two settings and review logs for LDAP auth events not followed by an OTP challenge.
