CVE-2025-6895

Estado: AplazadaCrítica (9.8)—

The Melapress Login Security plugin for WordPress is vulnerable to Authentication Bypass due to missing authorization within the get_valid_user_based_on_token() function in versions 2.1.0 to 2.1.1. This makes it possible for unauthenticated attackers who know an arbitrary user meta value to bypass authentication checks and log in as that user.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
