Versions 2.5.0 through 2.66.0 of the CVAT tool are vulnerable to a cross-site scripting (XSS) attack due to improper handling of media types for annotation guide assets. This vulnerability allows an attacker to manipulate the Content-Type header, potentially executing malicious JavaScript in the victim's browser. Organizations using affected versions should prioritize upgrading to version 2.67.0 to mitigate the risk of exploitation.

Original NVD Description

CVAT is an open source interactive video and image annotation tool for computer vision. Versions 2.5.0 through 2.66.0 contain a XSS vulnerability that can be accessed through annotation guide assets. When CVAT serves the files attached to an annotation guide, it labels them with a media type ( Content-Type ) that the attacker can influence, so instead of treating an uploaded file as plain data, the victim's browser can be told to treat it as an HTML page and run any JavaScript inside it. This issue has been fixed in version 2.67.0.
