Summary
hydra-ray-launcher from 1.1.0.dev1 before 1.2.2 and from 1.4.0.dev4 before 1.4.0rc2 contains an arbitrary module import flaw (CWE-470) in its ray_pkg_version OmegaConf resolver, which passes input to importlib.import_module(). A local attacker with low privileges who controls configuration values or command-line overrides can make the application import any installed module, which runs that module's import-time side effects in the application process.

Description from the CNA
hydra-ray-launcher 1.1.0.dev1 before 1.2.2 and 1.4.0.dev4 before 1.4.0rc2 contains an arbitrary module import vulnerability via the ray_pkg_version OmegaConf resolver passing input to importlib.import_module(). Attackers controlling configuration values or command-line overrides can supply a ray_pkg_version interpolation to import any installed module, triggering its import-time side effects in the application process.
