Summary
Apache Traffic Server from 8.0.1 through 8.1.11, from 9.0.0 through 9.2.15, from 10.0.0 through 10.1.4, and from 10.2.0 is affected. The experimental magick plugin passes client query strings unfiltered to ImageMagick convert arguments in its default unsigned configuration, a failure to neutralize argument delimiters (CWE-88). An unauthenticated remote attacker can control convert arguments, with high impact on confidentiality, integrity and availability.
