Contrast Assess more accurately detects Path Traversal vulnerabilities. Contrast Assess and Protect more accurately detect vulnerabilities and attacks respectively in Apache Struts based applications. Contrast Protect more accurately detects SQL Injection attacks.

This release includes breaking changes to Contrast Assess route coverage reporting when used with on-premise Contrast servers version 3.7.2 and older.

When WebSphere users configured their WebSphere services with custom TLS certificates, the Contrast Java agent prematurely initialized WebSphere's certificate manager as a side-effect. This caused the WebSphere TLS connections to fail unexpectedly. This issue has been resolved by adding a special exception for WebSphere to Contrast's TLS initialization whereby Contrast will use an isolated `SSLSocketFactory` instead of the Java runtime's default system socket factory.

When users configure their application with a session-based vulnerability auto-verification policy, and the user does not configure their Contrast agent with an explicit session_id configuration parameter, then Contrast wrongfully auto-verifies vulnerabilities. We resolved this issue by fixing a race condition, so we can ensure that auto-verification will work as expected when the user has configured their agent to use the contrast.agent.java.standalone_app_name configuration.
