How to fix?

Upgrade Chainguard label-studio to version 1.23.0-r3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream label-studio package and not the label-studio package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. ASGIRequest allows a remote attacker to spoof headers by exploiting an ambiguous mapping of two header variants (with hyphens or with underscores) to a single version with underscores. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Tarek Nakkouch for reporting this issue.
