CVE-2026-92815

Status: DeferredHigh (8.7)—

changedetection.io through 0.60.6 fails to validate the Goto URL action in browser steps, allowing unauthenticated attackers to access internal addresses. Attackers can supply arbitrary internal URLs in the optional_value parameter to retrieve responses from restricted network locations.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Aplicación web expuesta (AV:N, PR:N, UI:N) permite SSRF via parámetro opcional sin validación de URL. CWE-918 confirma falta de validación en destino de URL, permitiendo acceso a recursos internos restringidos.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
