WAF Release - 2026-06-09 · Changelog
New updates and improvements at Cloudflare.
June 9, 2026
This release introduces new detections for a critical SQL injection vulnerability in Drupal installations utilizing PostgreSQL (CVE-2026-9082), alongside targeted protection for an unsafe deserialization flaw in the Mirasvit Cache Warmer extension (CVE-2026-45247). Additionally, this release includes coverage for a prototype pollution vector in Axios (CVE-2026-40175) and a new generic rule designed to identify and block sophisticated SQL Injection (SQLi) bypass attempts leveraging obfuscated boolean logic.
Key Findings
Impact
Successful exploitation of these vulnerabilities could allow unauthenticated attackers to execute arbitrary code, manipulate database contents, or induce application crashes, leading to severe operational disruption or complete server compromise. These newly deployed signatures intercept these advanced malicious payloads at the edge before they can interact with vulnerable software configurations.
