CVE-2025-24359 ASTEVAL Vulnerable to Maliciously Crafted Format Strings Leading to Sandbox Escape

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...

CVE-2025-24359

CVE-2025-24359 affects the Python package asteval prior to 1.0.6. The root cause is in the handling of FormattedValue AST nodes in on_formattedvalue, which uses the dangerous Str.format path (fmt.format(fstring =val)). This can allow an attacker who controls input to bypass restrictions and execu...
