NVD Description

Note: Versions mentioned in the description apply only to the upstream opensearch-dashboards-2 package and not the opensearch-dashboards-2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize() and equal() functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications that normalize or compare attacker-controlled URLs to enforce path-based policy can be bypassed, with a path that appears confined under an allowed prefix normalizing to a different location. Versions <= 3.1.0 are affected. Update to 3.1.1 or later.
