CVE-2024-31995
zcap has incomplete expiration checks in capability chains.
Impact
### Impact 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. ### Patches `@digitalbazaar/zcap` v9.0.1 fixes expiration checking. ### Workarounds A zcap could be revoked at any time. ### References https://github.com/digitalbazaar/zcap/pull/82
