petl is vulnerable to Improper Control of Generation of Code ('Code Injection')
78
High Risk
This Affects:
petlTL;DR
Affected versions of this package are vulnerable to Arbitrary Code Execution due to unsafe eval() usage in util.base.expr. The vulnerability occurs when user-controlled inputs s are improperly sanitized before being embedded into a lambda expression string that is dynamically evaluated. An attacker can exploit this by injecting malicious Python code within the input string, which breaks out of the intended lambda rec:context and executes arbitrary commands with the application's privileges, potentially leading to system compromise or data exfiltration.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
