What is CVE-2025-58437?

The vulnerability in Coder arises from insecure session handling within prebuilt workspaces. Specifically, a session token generated for users when initiating a workspace remains active even after a workspace is claimed. This allows a potentially unauthorized user to exploit the session token, leading to unauthorized access or actions on the workspace. Versions prior to 2.24.4 and 2.25.2 contain this flaw. To mitigate this issue, it is crucial to update Coder to the latest versions where this vulnerability has been addressed.

Affected Version(s)

coder >= 2.22.0, < 2.24.4 < 2.22.0, 2.24.4

coder >= 2.25.0, < 2.25.2 < 2.25.0, 2.25.2
