Action Pack 是一个用于处理并响应 Web 请求的框架。在 8.1.4.1 和 8.0.5.2 版本之前，当 ActionDispatch::Cookies 读取在密钥轮换（config.action_dispatch.cookies_rotations）下写入的签名或加密 Cookie，或者读取处于 :hybrid Cookie 序列化器迁移格式中的 Cookie 时，它会以当前格式将该 Cookie 写回响应中，且该写入操作会忽略 request.session_options[:skip] 选项。A

Vulnerability Title
Action Pack: Possible sensitive session information leak in Active Storage proxy mode
来源: CVE Program / CVE List V5
Vulnerability Description
Action Pack is a framework for handling and responding to web requests. Prior to 8.1.4.1 and 8.0.5.2, When ActionDispatch::Cookies reads a signed or encrypted cookie that was written under a rotated secret (config.action_dispatch.cookies_rotations) or in the format that a :hybrid cookie serializer migrates from, it writes the cookie back to the response in the current format, and that write ignores request.session_options[:skip]. ActiveStorage::DisableSession relies on that option to keep the session cookie off the public, immutable responses of the Active Storage proxy controllers, but those controllers still load the session, so a request carrying an old-format session cookie could receive the rewritten session cookie in Set-Cookie on a cacheable response. A shared cache that stores such a response together with its Set-Cookie header could then serve one user's session to later requesters of the same URL, or serve an attacker's session to other users. Applications are affected when they serve Active Storage files through the proxy controllers, have a cookie rotation or a :hybrid serializer migration configured, and run behind a cache that stores Set-Cookie on public responses. This is a path around the fix for CVE-2024-26144. This issue is fixed in versions 8.1.4.1 and 8.0.5.2.
