CVE-2026-26215
CWE-502Published: February 11, 2026· Updated: Feb 12, 2026
Official 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.
Technical Analysis
CVE-2026-26215 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
