Arbitrary Code Execution (ACE)

hydraoptunasweeper is vulnerable to arbitrary code execution. The vulnerability is due to improper validation of configuration-controlled dotted paths in hydra-optuna-sweeper, which allows an attacker to execute arbitrary importable Python code with the application's privileges by manipulating...

Hydra: Optuna custom_search_space can resolve and execute untrusted callables via get_method

Summary hydra-optuna-sweeper accepted a configuration-controlled dotted path in hydra.sweeper.customsearchspace, resolved it with the lower-level hydra.utils.getmethod API, and later invoked the returned callable. Hydra's object-lookup helpers intentionally trust their input and do not apply the...
