hydra-core is vulnerable to Code Injection
78
High Risk
This Affects:
hydra-coreTL;DR
Hydra passes logging configuration to Python's logging.config.dictConfig() without applying its target authorization policy. Handler classes, formatters, filters, and factory callables named in a configuration are resolved and invoked outside the instantiate() safeguards. Configuration content that is externally influenced can therefore execute code with the application's privileges when the logging config is loaded. The fix routes logging callable resolution through Hydra's target blacklist so unsafe targets are rejected.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application loads externally influenced logging configuration.
Background info
hydra-core is vulnerable to Code Injection in versions 0.0.1 - 1.3.5.
How to fix this
