Answer in brief
CVE-2025-71351 records a High severity (CVSS 7.6) vulnerability in picklescan - Remote Code Execution via timeit.timeit() Detection Bypass. The current sources do not mark it as known exploited. The current feed maps picklescan/picklescan (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.6. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

picklescan before 0.0.25 fails to detect malicious pickle files that use timeit.timeit() in the __reduce__ method, allowing remote code execution. Attackers can craft pickle files that import dangerous libraries like os and execute arbitrary system commands, which evade picklescan detection and execute when pickle.load() is called.
