Overview
Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key. An attacker can access another user's workout routine details, including day sequences, exercise structure, training logs, and statistics, by making API requests to endpoints with a previously cached response for the same routine identifier, as ownership checks are bypassed on cache hits.
Note:
This is only exploitable if the targeted user has previously accessed the relevant endpoint, resulting in a populated cache entry.
