Security Bulletin: The Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree (AST) node for each part of the expression, affects watsonx.data

Summary In scenarios where input size isn't limited, a malicious or inadvertent extremely large expression can consume excessive memory as the parser builds a huge AST. This can ultimately lead toexcessive memory usage and an Out-Of-Memory OOM crash of the process. This issue is relatively uncomm...

Arbitrary Code Execution

ASTEVAL is vulnerable to Arbitrary Code Execution. The vulnerability is due to improper handling of FormattedValue AST nodes due to the use of Python's str.format method, allowing attackers to bypass restrictions and execute arbitrary code...

CVE-2025-24359: Use of Externally-Controlled Format String

ASTEVAL is an evaluator of Python expressions and statements. Prior to version 1.0.6, if an attacker can control the input to the asteval library, they can bypass asteval's restrictions and execute arbitrary Python code in the context of the application using the library. The vulnerability is...

Bandit - Tool Designed To Find Common Security Issues In Python Code

Bandit is a tool designed to find common security issues in Python code. To do this Bandit processes each file, builds an AST from it, and runs appropriate plugins against the AST nodes. Once Bandit has finished scanning all the files it generates a report. Bandit was originally developed within...
