NVD Description

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

Middleware causes a prohibitive amount of heap allocations when processing malicious preflight requests that include a Access-Control-Request-Headers (ACRH) header whose value contains many commas. This behavior can be abused by attackers to produce undue load on the middleware/server as an attempt to cause a denial of service.
