{"id":"CVE-2021-41087","details":"in-toto-golang is a go implementation of the in-toto framework to protect software supply chain integrity. In affected versions authenticated attackers posing as functionaries (i.e., within a trusted set of users for a layout) are able to create attestations that may bypass DISALLOW rules in the same layout. 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). Exploiting this vulnerability is dependent on the specific policy applied. The problem has been fixed in version 0.3.0.","aliases":["GHSA-vrxp-mg9f-hwf3","GO-2022-0936"],"modified":"2026-07-09T12:20:31.874280Z","published":"2021-09-21T21:15:07.203Z","references":[{"type":"ADVISORY","url":"https://github.com/in-toto/in-toto-golang/security/advisories/GHSA-vrxp-mg9f-hwf3"},{"type":"FIX","url":"https://github.com/in-toto/in-toto-golang/commit/f2c57d1e0f15e3ffbeac531829c696b72ecc4290"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/in-toto/in-toto-golang","events":[{"introduced":"0"},{"fixed":"f2c57d1e0f15e3ffbeac531829c696b72ecc4290"}],"database_specific":{"cpe":"cpe:2.3:a:in-toto:in-toto-golang:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.3.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-41087.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
