CVE-2025-71375

The CVE-2025-71375 issue affects the Python package picklescan (prior to 0.0.34) and stems from failure to detect the built-in function _operator.methodcaller when scanning pickle files for malicious code. This oversight allows attackers to craft pickle payloads that evade detection and can lead ...

CVE-2025-71373 picklescan - Remote Code Execution via operator.methodcaller Detection Bypass

picklescan before 0.0.33 fails to detect operator.methodcaller function calls in pickle files, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle payloads using operator.methodcaller that execute arbitrary code when loaded, compromising systems relying on...

CVE-2025-71352

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...

PT-2026-50467

Name of the Vulnerable Software and Affected Versions picklescan versions prior to 1.0.4 Description An incomplete blocklist for the profile module fails to block the module-level profile.run function. This allows attackers to achieve arbitrary code execution via exec by crafting malicious pickle...

Picklescan does not block ctypes

Summary Picklescan doesnt flag ctypes module as a dangerous module, which is a huge issue. ctypes is basically a foreign function interface library and can be used to Load DLLs Call C functions directly Manipulate memory raw pointers. This can allow attackers to achieve RCE by invoking direct...

GHSA-769V-P64C-89PR PyTorch Model Files Can Bypass Pickle Scanners via Unexpected Pickle Extensions

CVE-2025-1889 Summary Picklescan fails to detect hidden pickle files embedded in PyTorch model archives due to its reliance on file extensions for detection. This allows an attacker to embed a secondary, malicious pickle file with a non-standard extension inside a model archive, which remains...
