Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The praisonai package (PyPI) versions 4.6.56 up to but not including 4.6.59 are affected. When LINEAR_WEBHOOK_SECRET is not set, the LinearBot webhook listener on 0.0.0.0 skips signature verification, so an unauthenticated network caller can send forged Linear webhook events that invoke the configured agent and can make the bot post comments to Linear. Upgrade to praisonai 4.6.59 or later; until then, set LINEAR_WEBHOOK_SECRET so that signature checks are enforced.
