On this page
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.

Explain CVE-2026-56712 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-56712?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-56712?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-56712 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
