An attacker with access to trusted private keys, may issue an attestation that contains a disallowed artifact by including path traversal semantics (e.g., foo vs dir/../foo).\n\n### Patches\nThe problem has been fixed in version 0.3.0.\n\n### Workarounds\nExploiting this vulnerability is dependent on the specific policy applied.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [in-toto-golang](http://github.com/in-toto/in-toto-golang)\n* Email us at [in-toto-public](mailto:in-toto-public@googlegroups.com)\n* If this is a sensitive security-relevant disclosure, please send a PGP encrypted email to santiagotorres@purdue.edu or jcappos@nyu.edu\n\n\n## Affected packages\n\n- `github.com/in-toto/in-toto-golang < 0.3.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/in-toto/in-toto-golang 0.3.0`","depth":"sunlit","depthScore":31,"depthScoreParts":{"impact":30.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
