CVE-2025-71378

picklescan - Remote Code Execution via Undetected cProfile.runctx in Pickle Files

picklescan before 0.0.30 fails to detect cProfile.runctx function calls in pickle file reduce methods, allowing attackers to execute arbitrary code. Malicious pickle files bypass picklescan detection and execute remote code when loaded via pickle.load().

CVSS 4.0 · 7.6 High EPSS < 1% KEV · Not listed
CVE-2026-53874

picklescan - Arbitrary Code Execution via Obfuscated eval Call

picklescan before 1.0.1 contains an unsafe deserialization vulnerability allowing unauthenticated users to execute arbitrary code by hiding eval calls nested under callable objects via getattr. Attackers can embed malicious code in pickle files that evades detection but executes when the pickle is loaded from untrusted sources.

CVE-2025-71348

picklescan - Arbitrary Code Execution via torch.utils._config_module.load_config Bypass

picklescan before 0.0.28 fails to detect malicious pickle files that invoke torch.utils._config_module.load_config function within reduce methods. Attackers can craft pickle files embedding arbitrary code that evades detection but executes during pickle.load, enabling remote code execution in supply chain attacks.

CVE-2025-71351

picklescan - Remote Code Execution via timeit.timeit() Detection Bypass

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.

CVE-2025-71357

picklescan - Arbitrary Code Execution via Undetected idlelib.pyshell.ModifiedInterpreter.runcommand

picklescan before 0.0.30 fails to detect malicious pickle files using idlelib.pyshell.ModifiedInterpreter.runcommand in reduce methods. Attackers can embed undetected code in pickle files that executes remote commands when loaded by victims.

CVE-2025-71320

picklescan - Remote Code Execution via Incomplete Disallowed Inputs

picklescan before 0.0.33 contains an incomplete deny-list that fails to block pydoc.locate and operator.methodcaller functions, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle files using these unblocked functions to achieve arbitrary code execution when the pickle is deserialized.

CVE-2025-71322

PickleScan - Unsafe Globals Check Bypass via pty.spawn Function

PickleScan before 0.0.33 fails to include the pty.spawn function in its unsafe globals list, allowing attackers to bypass security checks. Malicious actors can craft pickle payloads using pty.spawn to achieve arbitrary code execution when files are processed by PickleScan.

CVE-2025-71323

picklescan - Remote Code Execution via Unblocked ctypes Module

picklescan before 0.0.33 fails to block the ctypes module, allowing attackers to achieve remote code execution by invoking direct syscalls and accessing raw memory. Attackers can craft malicious pickle files using ctypes.WinDLL to load kernel32.dll and execute arbitrary commands, bypassing sandbox protections and gadget chain detection.

CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
CVE-2026-53873

picklescan - Arbitrary Code Execution via profile.run() Blocklist Bypass

picklescan before 1.0.4 contains an incomplete blocklist for the profile module that fails to block the module-level profile.run() function, allowing attackers to achieve arbitrary code execution via exec(). Attackers can craft malicious pickle files calling profile.run(statement) to execute arbitrary Python code while picklescan reports zero security issues.
