SCA: security update for hydra-core (GHSA-mwj6-rfh8-7qf4)

high Tenable Cloud Security Plugin ID 473820

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Hydra is a framework for elegantly configuring complex applications. From 1.3.4 until 1.3.7 and
 1.4.0.dev10, Hydra stores legacy instantiate target blocklists and related execution-policy collections in
 mutable module-level state. An attacker who controls multiple sibling target entries can resolve
 hydra._internal.target_policy.UNCONTROLLED_EXECUTION_TARGETS.discard through instantiate(), remove a
 denied target, and then invoke that target because sibling nodes are processed in insertion order against
 the same modified policy. The mutation persists in process-global state and can enable code execution with
 the application's privileges, while a narrow execution whitelist supplied by trusted Python code is not
 bypassed by the reported direct mutation path. This issue is fixed in versions 1.3.7 and 1.4.0.dev10.
 (CVE-2026-106439)

Solution

Update the hydra-core library and its related packages to version 1.3.7 or later.
