Real-World Exposure
github.com/argoproj/argo-eventsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Several HandleRoute endpoints make use of the deprecated ioutil.ReadAll(). ioutil.ReadAll() reads all the data into memory. As such, an attacker who sends a large request to the Argo Events server will be able to crash it and cause denial of service.
Eventsources susceptible to an out-of-memory denial-of-service attack:
- AWS SNS
- Bitbucket
- Bitbucket
- Gitlab
- Slack
- Storagegrid
- Webhook
Patches
A patch for this vulnerability has been released in the following Argo Events version:

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/argoproj/argo-events, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/argoproj/argo-events to 1.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-31054 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
