Описание
zcap has incomplete expiration checks in capability chains.
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.

`@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.
