Attackers are exploiting two critical WordPress vulnerabilities (CVE-2026-63030 and CVE-2026-60137) to enable pre-authentication remote code execution. The flaws, patched in WordPress versions 6.9.5 and 7.1 Beta 2, allow unauthenticated users to execute arbitrary code by chaining an SQL injection issue with a REST API route confusion bug. Security researchers observed widespread exploitation within hours of the patches being released.

SonicWall disclosed two zero-day vulnerabilities (CVE-2026-15409 and CVE-2026-15410) being exploited to compromise SMA1000 appliances, with attackers likely targeting ransomware.

Citrix disclosed six vulnerabilities in NetScaler ADC and Gateway, including a high-severity memory disclosure flaw (CVE-2026-8451) linked to the CitrixBleed vulnerability class. Researchers at watchTowr and others identified the flaws, which involve memory management issues and require patching and configuration adjustments to mitigate risks.

cPanel's authentication bypass vulnerability (CVE-2026-41940) is being actively exploited, affecting all supported versions since 11.40 and WP Squared. CISA added it to its KEV list, while cPanel released a patch addressing the flaw, which allows attackers to inject malicious data during login to bypass authentication.
