Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Argo Workflows versions 4.0.0 through 4.0.4 and 3.6.5 through 3.6.19, plus 3.7.0 through 3.7.13, are affected. A user with permission to create Workflow resources can submit a pod with a malformed pod-gc-strategy annotation that makes the controller panic and crash repeatedly, halting all workflow processing until the poisoned pod is deleted. Upgrade to 4.0.5 or 3.7.14; no workaround is listed.
