42Crunch Platform release, June 4, 2025

This 42Crunch API Security Platform release brings scan rules defined in 42Crunch Platform into API Conformance Scan v2 and new checks to API Security Audit.

New features

The following are the new features and improvements to the existing ones in this release.

Improvements to Conformance Scan

When scanning your API, Scan v2 now takes into account scan rules that have been applied to the API, either as the default rule in your organization or through tags. This allows centrally defining scan rules and reflecting them in the scan results, regardless of the scan version (v1 or v2).

In addition to the 2019 version, the OWASP API Security Top 10 2023 vulnerabilities can now also be used as a criteria in scan security quality gates (SQGs), both for Scan v1 and v2.

We have also improved the status messages for the latest scan with your reference scan configuration on the API summary page: the reason why the scan failed or was incomplete is now clearly spelled out so that it is easier for you to correct things. This also applies to both Scan v1 and v2.

By default, Scan v2 now automatically normalizes any URLs that it calls during the scan, replacing slashes (/) that are repeated multiple times with single slashes in API calls: for example, instead of calling https://server.com//endpoint/name, the scan now calls the URL https://server.com/endpoint/name. However, if your API implementation requires using multiple slashes, you can change the behavior in scan settings. For more details, see Settings for Scan v2.

New check for Security Audit

Security Audit now raises an issue ((v3-/v3_1-)warning-serverurl-normalization) if your base path (OAS v2) or server URL (OAS v3 or v3.1) has a trailing slash (/). This can cause API consumers to wrongly parse the URLs for API calls, leading them to call the wrong URL.

For more details, see:

The new check does not affect the audit score of your APIs.

Other improvements

Support for the OpenAPI Specification v3.1 has now been also included in our CI/CD plugins for Bamboo and Tekton.

We have also fixed the following bugs:

  • In certain cases, an API Firewall instance could take too much resources on a graceful restart. The resource consumption has now been better optimized.
  • When a user belonging to an organization with SSO integration tried to access 42Crunch Platform but the attempt was rejected by the identity provider, the rejection was not properly handled in downstream services but could cause issues. The handling of rejections has now been fixed and downstream services process it without problems.

Compatibility

This section lists the compatible Docker images for some of the components of 42Crunch API Security Platform, as well as other possible compatibility details.

Changed behavior

Scan v2 now takes scan rules defined in 42Crunch Platform into account when it runs a scan. Depending on your API and scan rules you have applied to it, this may affect the scan results.

Known issues

This release has the following known issues.

Manage teams permission not shown on list of users

The permission to manage teams is not yet shown on the list of users in your organization, but you can view all permissions that a user has by clicking the permission column. This permission also does not yet have a shortcut that you could use when searching by permission.

These will be fixed in a future release.

Changing tagging on an API may trigger an unrelated error on the UI

Sometimes applying tags to or removing them from an API may trigger an unrelated error on failing to fetch the SQG approval report for the API. This happens if the API in question has been scanned on-premises and the scan has finished after you arrived on the API Summary page, because the UI cannot find the latest on-premises scan report and the associated approval report. Refreshing the page gets the latest reports and resolves the issue.

Tagging and untagging the API is not affected by this error: tags get correctly applied and removed in any case.

This will be fixed in a future release.

Data dictionary duplication

Duplicating a data dictionary does not yet duplicate the values in it.

This will be fixed in a future release.

Scan customization rules may lead to no response codes being accepted.

In some cases, scan rules can lead to HTTP status response codes in API responses that are normally expected (for example, HTTP 401 or HTTP 404) to be treated as unexpected. This in turn can lead to a false positive in the scan results.

By default, the expected HTTP status response codes that are defined in scan rules applied to the scanned API take preference over the response codes that Conformance Scan would otherwise expect. However, this can cause problems in scan process if your scan rule only skips header or response body analysis but does not define any expected response codes, either for happy path requests or for particular test IDs. This results in the scan rule to have null defined as the expected response code, and because the scan rule takes preference over the default scan behavior, no response codes except null are accepted. This in turn means that some tests are incorrectly flagged as returning unexpected response codes when they were in fact successful.

We are currently investigating the best way how to reconcile the designed behavior of Conformance Scan and scan rules in these cases, and this issue will be fixed in a future release.
