Lack of data validation - Path Traversal In github.com/argoproj/argo-events
Description
Insecure path traversal in Git Trigger Source can lead to arbitrary file read
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
