PYSEC-2026-4223 Hydra instantiate target blacklist bypasses permit code execution

Summary Hydra's instantiate API resolves and invokes Python callables named by the target field in configuration. The target blacklist introduced for CVE-2026-68508 was incomplete. Representative bypasses included execution wrappers such as timeit.timeit, executable deserialization through...

PYSEC-2026-4222 Hydra: Mutable instantiate policy sets allow target blocklist bypass

Summary Hydra's legacy instantiate target blocklists and related execution-policy collections are stored in mutable module-level state. Because locate can resolve attributes on imported objects, a configuration can resolve a mutation method such as .discard, modify the active policy, and then...

CVE-2026-106442

A flaw was found in hydra-core. The instantiate mechanism does not properly validate callable targets against its blocklist, allowing execution wrappers and deferred calls to bypass authorization checks. An attacker who convinces an application or user to process untrusted configuration files can...

CVE-2026-106442

Hydra is a framework for elegantly configuring complex applications. From 1.3.4 until 1.3.6 and 1.4.0.dev9, the instantiate target blacklist introduced for CVE-2026-68508 incompletely checks the effective callable selected by the target field. Execution wrappers such as timeit.timeit, executable...

CVE-2026-106439

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 resol...

CVE-2026-106442

The Hydra configuration framework is vulnerable to code execution in versions 1.3.4 through 1.3.6 and 1.4.0.dev9 . The instantiate() target blacklist, originally intended to mitigate CVE-2026-68508, fails to sufficiently validate the effective callable selected by the target field. Attackers can ...
