CVE-2026-32301

CVE-2026-32301 affects Centrifugo up to 6.6.x. An unauthenticated attacker can cause SSRF by crafting a JWT whose iss or aud claims interpolate into a dynamic JWKS endpoint URL before token verification, triggering Centrifugo to make a request to an attacker‑controlled destination. The dynamic JW...
