{"id":"CVE-2024-31995","aliases":["GHSA-hp8h-7x69-4wmv"],"url":"https://o3.security/vulnerability/CVE-2024-31995","summary":"zcap has incomplete expiration checks in capability chains.","details":"`@digitalbazaar/zcap` provides JavaScript reference implementation for Authorization Capabilities. Prior to version 9.0.1, when invoking a capability with a chain depth of 2, i.e., it is delegated directly from the root capability, the `expires` property is not properly checked against the current date or other `date` param.  This can allow invocations outside of the original intended time period.  A zcap still cannot be invoked without being able to use the associated private key material. `@digitalbazaar/zcap` v9.0.1 fixes expiration checking. As a workaround, one may revoke a zcap at any time.","published":"2024-04-10T21:57:41.129Z","modified":"2026-07-15T01:49:15.483886709Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@digitalbazaar/zcap","fixedVersion":"9.0.1"}],"fix":{"url":"https://github.com/digitalbazaar/zcap/commit/261eea040109b6e25159c88d8ed49d3c37f8fcfe","label":"digitalbazaar/zcap@261eea0"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/31xxx/CVE-2024-31995.json"},{"type":"ADVISORY","url":"https://github.com/digitalbazaar/zcap/security/advisories/GHSA-hp8h-7x69-4wmv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-31995"},{"type":"FIX","url":"https://github.com/digitalbazaar/zcap/commit/261eea040109b6e25159c88d8ed49d3c37f8fcfe"},{"type":"FIX","url":"https://github.com/digitalbazaar/zcap/commit/55f8549c80124b85dfb0f3dcf83f2c63f42532e5"},{"type":"FIX","url":"https://github.com/digitalbazaar/zcap/pull/82"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:15.483886709Z"}}
