EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Grav Login Plugin adds login, basic ACL, and session wide messages to Grav. Prior to 3.8.11, the Grav Login plugin login.regenerate2FASecret task checks only that the pending-session user exists rather than requiring $user->authorized. After submitting a victim's correct password, an attacker can invoke taskRegenerate2FASecret() during the pending TOTP challenge, overwrite twofa_secret, read the replacement secret from the response, calculate a valid code, and complete authentication without the victim's second factor. This issue is fixed in version 3.8.11.
