description

Label Studio before 1.23.2 and label-studio-sdk before 2.1.2 can make server-side requests to internal URLs supplied through task image data during image-bearing exports. An authenticated user who can create such tasks may access internal HTTP responses and potentially expose an organization owner's API token.

mitigation

Upgrade Label Studio to 1.23.2 or later and label-studio-sdk to 2.1.2 or later. Until upgraded, restrict untrusted users from creating tasks with externally supplied image URLs or running image-bearing exports.

fixed in 1.23.2, 2.1.2
