How to fix?

There is no fixed version for Debian:12 node-ajv.

NVD Description

Note: Versions mentioned in the description apply only to the upstream node-ajv package and not the node-ajv package as distributed by Debian. See How to fix? for Debian:12 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.
