Authenticated cache disruption via missing permission checks
Published Feb 20, 2026 · Updated Feb 20, 2026
Access control failure in yeqifu warehouse through aaf29962ba407d22d991781de28796ee7b4670e4 allows remote authenticated users to disrupt caches. CacheController exposes deleteCache, removeAllCache, and syncCache without permission checks, allowing any logged-in account to evict entries, clear the cache, or force synchronization. Exploitation requires a valid session and can degrade performance, expose stale data, and destabilize the application.
