Answer in brief
CVE-2025-71352 records a High severity (CVSS 8.1) vulnerability in picklescan - Remote Code Execution via Undetected trace.Trace.runctx in Pickle Files. 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 8.1. 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 0.0.29 fails to detect the built-in Python trace.Trace.runctx function when used in pickle file reduce methods, allowing attackers to execute arbitrary code. Remote attackers can craft malicious pickle files with trace.Trace.runctx payloads that bypass picklescan detection and execute code upon pickle.load() invocation.
