CVE-2026-13510 LOW POC PATCH Monitor

Deployment authentication token weakness in SimStudioAI Sim up to 0.6.92 leaks a truncated SHA-256 derivative of the encrypted deployment password inside base64-encoded auth cookies, enabling offline hash cracking and potential token forgery against password-protected deployments. The vulnerable Password Protection Handler embeds only the first 8 hex characters (32 bits) of an unsalted SHA-256 hash of the encrypted password directly in the unprotected token payload - a CWE-328 use of weak hash - allowing an attacker who obtains the cookie to brute-force the narrow hash space and fingerprint or bypass deployment authentication. No patch has been merged; fix PR #4760 is pending acceptance, and a public proof-of-concept is available at https://github.com/simstudioai/sim/issues/4759.
