Description
Impact
We are not aware of any exploits. This is a pro-active fix.
Impacted:
- You are running Argo Server < v3.0 with
--secure=trueor >= v3.0 with--secureunspecified (note - running in secure mode is recommended regardless). - The attacker is within your network. If you expose Argo Server to the Internet then "your network" is "the Internet".
The Argo Server's keys are packaged within the image. They could be extracted and used to decrypt traffic, or forge requests.
Patches

Workarounds
- Make sure that your Argo Server service or pod are not directly accessible outside of your cluster. Put TLS load balancer in front of it.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/argoproj/argo-workflows/v3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/argoproj/argo-workflows/v3 to 3.0.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6c73-2v8x-qpvm is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
