Picklescan does not block ctypes

SummaryPicklescan 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-2026-1785 Picklescan has Incomplete List of Disallowed Inputs

Summary Currently picklescanner only blocks some specific functions of the pydoc and operator modules. Attackers can use other functions within these allowed modules to go through undetected and achieve RCE on the final user. Particularly pydoc.locate: Can dynamically resolve and import arbitrary...

Picklescan vulnerable to Arbitrary File Writing

SummaryPicklescan has got open and shutil in its default dangerous blocklist to prevent arbitrary file overwrites. However the module distutils isnt blocked and can be used for the same purpose ie to write arbitrary files. DetailsThis is another vulnerability which impacts the downstream user.By...

vLLM vulnerable to remote code execution via transformers_utils/get_config

PYSEC-2026-1217 BBOT's gitlab.py exposes globally configured "gitlab" API key

Summary bbot's gitlab.py sends the user's "gitlab" API key to on-premise GitLab instances. If a user has configured a gitlab.com API key using this mechanism, it may be leaked to an attacker-controlled server. Impact A user with a "gitlab" API key configured who uses bbot to scan a malicious...

PYSEC-2026-1216 BBOT's git_clone.py can expose users' GitHub API keys to an attacker-controlled webserver

DataChain Vulnerable to Deserialization of Untrusted Data from Environment Variables

The DataChain library reads serialized objects from environment variables such as DATACHAINMETASTORE and DATACHAINWAREHOUSE in the loader.py module. An attacker with the ability to set these environment variables can trigger code execution when the application loads...

Skops has Inconsistent Trusted Type Validation that Enables Hidden `operator` Methods Execution

SummaryAn inconsistency in OperatorFuncNode can be exploited to hide the execution of untrusted operator.xxx methods. This can then be used in a code reuse attack to invoke seemingly safe functions and escalate to arbitrary code execution with minimal and misleading trusted types.Note: This repor...
