Arbitrary code execution via pre_dispatch eval
Published Sep 26, 2022 · Updated Sep 17, 2024
Code injection in Joblib before 1.2.0 allows attackers to execute arbitrary Python code through Parallel's pre_dispatch argument. Parallel passes a string-valued pre_dispatch expression to Python eval without restricting built-ins or permissible syntax. Exploitation requires an application to pass attacker-controlled text into pre_dispatch; code runs with that application's privileges.
