hydra-core is vulnerable to Code Injection

CVE Score
High
Code Injection
TL;DR
Hydra's hydra.utils.instantiate() resolves and calls Python objects named by the _target_ string in a configuration node. When a consuming application passes untrusted configuration into this function, it can lead to arbitrary code execution, allowing reading or modifying files, credentials, and application state. The fix adds a default blocklist of high-risk callables and modules and permits an explicit allowlist override.
How do I fix this?
Upgrade the hydra-core library to the patch version.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application passes untrusted config to hydra.utils.instantiate().
