CVE-2025-5174: 
Python vulnerability analysis and mitigation

A vulnerability (CVE-2025-5174) was discovered in erdogant pypickle versions up to 1.1.5, affecting the load function in pypickle/pypickle.py. The vulnerability involves insecure deserialization that could lead to remote code execution. The issue was disclosed on May 16, 2025, and was patched in version 2.0.0 (Github Issue, NVD).

The vulnerability stems from the load() function using Python's pickle.load() without proper input validation or sanitization. The issue is classified under CWE-502 (Deserialization of Untrusted Data) and CWE-20 (Improper Input Validation). The vulnerability has been assigned a CVSS v3.1 Base Score of 7.8 (HIGH) with vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local access requirements but high potential impact (NVD).

The vulnerability allows attackers to execute arbitrary code when a malicious pickle file is loaded, potentially leading to remote system compromise. The attack requires local access to be successful, but can result in complete system compromise through arbitrary command execution (Github Issue, Wiz).

The vulnerability has been fixed in pypickle version 2.0.0. The update includes several security mechanisms: implementation of validation checks for high-risk modules before loading, restrictions on save locations, and path traversal detection. Users are strongly recommended to upgrade to version 2.0.0. The patch is identified as 14b4cae704a0bb4eb6723e238f25382d847a1917 (Github Release).
