CVE-2026-54631 Details
Description
Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.1, the file .env committed in the Part-DB repository contains a fixed value for APP_SECRET (a03498528f5a5fc089273ec9ae5b2849). The official Docker image jbtronics/part-db1 does not override or randomize this value at container start-up. Because Symfony uses APP_SECRET (via kernel.secret) as the HMAC key for signing remember-me cookies, any attacker who knows the secret -- or fetches it from the public repository -- can forge an arbitrary-user remember-me cookie and gain a fully authenticated session with no credentials required. This issue has been patched in version 2.12.1.
A vulnerability exists in Part-DB versions prior to 2.12.1 due to a hardcoded APP_SECRET value in the .env file, which is tracked in the repository. The official Docker image jbtronics/part-db1 does not override this value at startup. Symfony uses APP_SECRET as the HMAC key for signing remember-me cookies, allowing an attacker who knows the secret or retrieves it from the public repository to forge a remember-me cookie for any user, including admin, and gain access to their account without credentials. This vulnerability affects all default Docker deployments of Part-DB 2.12.0 or earlier.
Users are advised to update to Part-DB version 2.12.1 or later. After updating, generate a new random 32-character string for APP_SECRET and place it in the .env.local file or the environment section of the docker-compose.yaml file.
