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
A path traversal issue was found in the (g *GitArtifactReader).Read() API. Read() calls into (g *GitArtifactReader).readFromRepository() that opens and reads the file that contains the trigger resource definition:
func (g *GitArtifactReader) readFromRepository(r *git.Repository, dir string)
No checks are made on this file at read time, which could lead an attacker to read files anywhere on the system. This could be achieved by either using symbolic links, or putting ../ in the path.
Patches
A patch for this vulnerability has been released in the following Argo Events version:
v1.7.1

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-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-2022-25856 is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
