CVE-2025-69872Public exploit

Local code execution via poisoned pickle cache

Published Feb 11, 2026 · Updated Feb 11, 2026

Unsafe deserialization in DiskCache through 5.6.3 allows local users to execute arbitrary code by poisoning a writable cache directory. Disk.fetch passes serialized cache keys and values from cache.db or .val files directly to pickle.load or pickle.loads, which invokes attacker-selected callables. Exploitation requires filesystem write access to the cache directory and a later cache read by the victim application; successful code runs with that process's permissions.
