Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Part-DB 是一款用于电子元件管理的开源库存管理系统。在 2.1.2.1 版本之前，Part-DB 代码仓库中提交的 文件里， 配置项被硬编码为一个固定值（ ）。官方 Docker 镜像 在容器启动时并未覆盖或随机化该值。由于 Symfony 框架通过 使用 作为 HMAC 密钥来签署“记住我”（remember-me）Cookie，任何知晓该密钥的攻击者（或从公开仓库中获取该密钥）均可伪造任意用户的“记住我”Cookie，从而在无需提供任何凭证的情况下获得完全认证的会话。该漏洞已在 2.12.1 版本中修复。

Vulnerability Title
Part-DB: Hardcoded APP_SECRET enables forged remember-me cookie
Source: CVE Program / CVE List V5
Vulnerability 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.
