GHSA-p8rw-8qj3-hf33: omnigent (CVE-2026-62677)

Package	Ecosystem	Affected	Fixed in
omnigent	PyPI	<0.3.0	0.3.0

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Omnigent versions before 0.3.0 let an authenticated user gain arbitrary read and write access to the host filesystem on a runner, and read the runner's environment secrets, by uploading an agent bundle whose os_env cwd points outside the intended workspace. This applies only to runners where OMNIGENT_RUNNER_WORKSPACE is not set. Upgrade to Omnigent 0.3.0 or later. Setting OMNIGENT_RUNNER_WORKSPACE on runners is a deployment-level mitigation, though the source notes it is not a complete defense.
