CVE-2026-62669 Details

UNDERGOING ENRICHMENT

The CVE is currently being enriched by the Volerion team. The enrichment process results in the association of reference link tags, CVSS, and CPE applicability statement data.

Description

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.
