ZAP Updates 2022 August

Posted 1027 Words

Lots of things are going on with ZAP but I’ve realised that many of you will not be aware of all of them.

So here is a summary of what has been going on this month - let us know if you find this useful, if it is then this could become a regular feature 😁.

ZAP Version 2.12.0 - Coming Soon

On 19th August we announced that the next major version of ZAP, 2.12.0, will be “coming soon”. There’s no exact date yet, but most of the changes are already in the weekly releases, so download the most recent one if you want to see what it will look like.

New Add-on: Param Digger

This month saw the first release and associated blog post for the Param Digger add-on. This is being developed by Arkaprabha Chakraborty as part of Google Summer of Code 2022.


Statistics from the 2 main ZAP repos.


Excluding merges, 7 authors have pushed 18 commits to main and 18 commits to all branches. On main, 324 files have changed and there have been 3,438 additions and 1,047 deletions.


Excluding merges, 10 authors have pushed 70 commits to main and 70 commits to all branches. On main, 1,015 files have changed and there have been 22,725 additions and 2,555 deletions.

Ongoing Work


Work to upgrade the ZAP networking stack to support modern protocols is ongoing. The next phase will add initial support for HTTP/2 - this is a significant change and we expect this to be merged after 2.12.0 has been released.

Spider Migration to an Add-on

The traditional spider has been moved from the core into the zap-extensions repo. This will allow us to update the spider without requiring a full ZAP release.

For more details see the Spider News blog post.

Modern Web App Handling

We do know that ZAP could handle modern web apps better. Work is going on to make this happen, but it is not publicly available at this time.

ZAP vs OWASP Benchmark

ZAP is run against a set of test applications every day - for more details see the Test Scans page.

This month OWASP Benchmark was added to that list. Initially we are just testing ZAP vs the Command Injection vulnerabilities but we will be expanding support to cover all of the relevant tests a.s.a.p.

For more details see ZAP vs OWASP Benchmark.

HUD Problems on Firefox

Unfortunately the ZAP HUD is no longer working with the latest versions of Firefox. This is due to recent Firefox changes, the HUD still works with Chrome. We are trying to fix this problem but it is non trivial - more details in the issue #1135.

Install / Update Add-on First In Automation

The core has been changed to ensure that any add-ons installed or updated from the command line are processed first. This means that it will now be possible to use command line options for newly installed add-ons, and for those add-ons to be correctly used in an Automation Framework plan.

ZAP Test Scans

ZAP now scores 80% against Google Security Crawl Maze, up from 73%.

When we first started testing ZAP against Crawl Maze in March 2022 it only scored 50% so you can see how it has improved.

Website Updates

The following new pages were added:

Weekly / Live - Alert Issue

On August 24th we became aware of an issue in the recent weekly and live releases. The problem only appears to have occurred when reading alerts from the Sites tree - as far as we aware the reports should have been generated correctly. This seems to have affected passive scan results more than active scan ones. We have fixed the issue and have re-released the weekly and live versions. If you are using either of these releases we strongly recommend that you update them now.
