Detailsinfo

A vulnerability has been found in zyddnys manga-image-translator up to beta-0.3 and classified as critical. Affected by this vulnerability is the function pickle.loads of the file /simple_execute/ of the component FastAPI Endpoint. The manipulation with an unknown input leads to a deserialization vulnerability. The CWE definition for the vulnerability is CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed by Valentin Lobstein as 1116. It is possible to read the advisory at chocapikk.com. This vulnerability is known as CVE-2026-26215 since 02/11/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication.
