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
Credits
Disclosed by Ada Logics in a security audit sponsored by CNCF and facilitated by OSTIF.
