The Contest Gallery WordPress plugin before 13.1.0.6 does not have capability checks and does not sanitise or escape the cg-search-user-name-original parameter before using it in a SQL statement when exporting users from a gallery, which could allow unauthenticated to perform SQL injections attacks, as well as get the list of all users registered on the blog, including their username and email address

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
