CVE-2025-71366 picklescan - Arbitrary Code Execution via torch.utils.bottleneck.__main__.run_cprofile

picklescan before 0.0.28 fails to detect malicious torch.utils.bottleneck.main.runcprofile function calls in pickle files, allowing attackers to bypass safety checks. Remote attackers can embed undetected code in pickle files to achieve arbitrary code execution when victims load the files...

CVE-2025-71371 picklescan - Remote Code Execution via code.InteractiveInterpreter Detection Bypass

picklescan before 0.0.29 fails to detect malicious pickle files using code.InteractiveInterpreter.runcode in reduce methods. Attackers can craft pickle payloads that bypass picklescan detection and execute arbitrary code when loaded via pickle.load...

GHSA-VVPJ-8CMC-GX39 PickleScan's pkgutil.resolve_name has a universal blocklist bypass

Summary pkgutil.resolvename is a Python stdlib function that resolves any "module:attribute" string to the corresponding Python object at runtime. By using pkgutil.resolvename as the first REDUCE call in a pickle, an attacker can obtain a reference to ANY blocked function e.g., os.system,...

GHSA-4675-36F9-WF6R 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...

PYSEC-2025-113

Fickling is a Python pickling decompiler and static analyzer. Versions prior to 0.1.6 had a bypass caused by pty missing from the block list of unsafe module imports. This led to unsafe pickles based on pty.spawn being incorrectly flagged as LIKELYSAFE, and was fixed in version 0.1.6. This impact...

GHSA-R7V6-MFHQ-G3M2 Fickling has Code Injection vulnerability via pty.spawn()

Fickling Assessment Based on the test case provided in the original report below, this bypass was caused by pty missing from our block list of unsafe module imports as previously documented in 108, rather than the unused variable heuristic. This led to unsafe pickles based on pty.spawn being...
