Unknown · Label Studio · CVE-2025-47783
Name of the Vulnerable Software and Affected Versions:
Label Studio versions prior to 1.18.0
Description:
A vulnerability in Label Studio allows an attacker to inject a malicious script into the context of a web page, which can lead to data theft, session hijacking, unauthorized actions on behalf of the user, and other attacks. The issue is reproducible when sending a properly formatted request to the "POST /projects/upload-example/" endpoint. The vulnerability is located at `label studio/projects/views.py` and is related to the `label config` parameter.
Recommendations:
For versions prior to 1.18.0, update to version 1.18.0, which contains a patch for the issue. As a temporary workaround, consider restricting access to the `POST /projects/upload-example/` endpoint and avoiding the use of the `label config` parameter until the update is applied.
