Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Hydra (hydra-core) versions before 1.3.6, and 1.4.0.dev0 through 1.4.0.dev8, let logging configuration resolve and invoke arbitrary importable classes and factories without Hydra's target policy applying. An attacker who can control a Hydra logging configuration could run code with the application's privileges when logging is set up. Upgrade to 1.3.6, or to 1.4.0.dev9 or later if using the 1.4 prerelease line; on 1.4 and later, a narrow execution whitelist from trusted Python code can constrain custom logging targets.
