@digitalbazaar/zcap fixed: 9.0.1 
npm install @digitalbazaar/zcap@9.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @digitalbazaar/zcap

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-31995, inspect your project dependencies using npm:

npm ls @digitalbazaar/zcap

Analyze the terminal output to locate any version of @digitalbazaar/zcap in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.0.1), your application is affected.

Note: The npm ls @digitalbazaar/zcap command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-613: Insufficient Session Expiration, where according to wasc, "insufficient session expiration is when a web site permits an attacker to reuse old session credentials or session ids for authorization.". In @digitalbazaar/zcap, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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
