NVD Description

Note: Versions mentioned in the description apply only to the upstream commercial-gitlab-rails-ee-fips-19.3 package and not the commercial-gitlab-rails-ee-fips-19.3 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

undici's decompress interceptor decompresses response bodies according to the untrusted Content-Encoding header. While the number of content-encoding layers is capped, the total decompressed output size is unbounded and there is no configuration option to limit it. A malicious or faulty upstream can therefore return a small compressed payload, a compression bomb, that expands to hundreds of megabytes or more in client memory, an asymmetric resource consumption that can exhaust memory and crash the process. This affects undici versions from 7.15.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.
