Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
