# CVE-2026-56712: Replicate Cog 0.23.1 SSRF via cog.File and cog.Path URL Inputs

Status: published. Published: 2026-11-09. Updated: 2026-11-09.

Replicate Cog through 0.23.1 contains a server-side request forgery vulnerability that allows attackers to cause the Cog process to make server-side HTTP requests by submitting prediction inputs with attacker-controlled URLs that are not validated against the resolved destination host or IP before fetching. Attackers can supply malicious URLs or exploit HTTP redirects in cog.File and cog.Path predictor inputs to force requests to internal addresses, potentially exposing sensitive internal services or credentials.
