NVD Description

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

source-map-js through 1.2.1 fails to validate the per-section offset line value in indexed source maps, allowing attackers to specify arbitrary numeric values. Attackers can supply extremely large offset line values that cause synchronous event loop blocking for extended periods, preventing the service from handling other requests.
