CVE-2026-56676: CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition in decolua 9routerCVE-2026-56676
0

CVE-2026-56676 is a time-of-check to time-of-use (TOCTOU) race condition vulnerability in decolua's 9router prior to version 0.5.2. The issue arises because the product validates image URLs by resolving the host before fetching, but performs the actual server-side image fetch with a separate DNS resolution. An authenticated attacker with access to the LLM proxy can exploit this by using a vision-capable model and an attacker-controlled DNS name that initially resolves to a public IP and then rebinds to an internal address. This allows the attacker to make server-side requests to internal-only HTTP services. The vulnerability is fixed in version 0.5.2.
