DAST 2026.5.2

Summary: PortSwigger released Burp Suite DAST 2026.5.2 on 8 June 2026, adding Negotiate auth scheme and SPNEGO encoding options to NTLM credential setup for site configurations and upstream proxy settings. The options apply to both NTLM v1 and NTLM v2 and match those already in scan configuration, and the release also fixes an issue where Cloud customers' scans were incorrectly marked as failed.

Why it matters: The fix addresses scans being wrongly marked as failed for Cloud customers, which means teams relying on those scan results may have been acting on false failure signals before this release.
