CVE-2026-26215
manga-image-translator version beta-0.3 and prior in shared API mode contains an unsafe deserialization vulnerability that can lead to unauthenticated remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
manga-image-translator version beta-0.3 and prior in shared API mode contains an unsafe deserialization vulnerability that can lead to unauthenticated remote code execution. The FastAPI endpoints /simple_execute/{method} and /execute/{method} deserialize attacker-controlled request bodies using pickle.loads() without validation. Although a nonce-based authorization check is intended to restrict access, the nonce defaults to an empty string and the check is skipped, allowing remote attackers to execute arbitrary code in the server context by sending a crafted pickle payload.
