CVE-2026-1238

Estado: AplazadaAlta (7.2)—

The SlimStat Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fh' (fingerprint) parameter in all versions up to, and including, 5.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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).
