Critical WSO2 Vulnerability Allow Hackers to Gain Full Admin Access
WSO2 discloses CVE-2026-5430 (CVSS 10.0), an unauthenticated JWT authentication bypass allowing admin account takeover across its API management products.
WSO2 disclosed CVE-2026-5430, a critical authentication bypass (CVSS 10.0; 9.8 for single-tenant deployments) in advisory WSO2-2026-5328. The flaw stems from insecure JWT processing: tokens signed with unsupported algorithms bypass authentication checks, potentially granting unauthenticated attackers administrative access. Affected products include WSO2 API Control Plane 4.5.0-4.6.0, API Manager 4.1.0-4.6.0, Traffic Manager 4.5.0-4.6.0, and Universal Gateway 4.5.0-4.6.0. Fixes are available via update levels such as API Manager 4.6.0 update 21 or by migrating to unaffected releases.

cPanel LiteSpeed Web Server Vulnerability Allows Shared Server Users to Gain Root-Level Access
Critical LiteSpeed Enterprise flaw fixed in 6.3.7 lets low-privilege shared-hosting users escalate to root and bypass CageFS.
cPanel issued an urgent advisory for a critical privilege escalation in LiteSpeed Web Server Enterprise versions before 6.3.7, allowing a low-privilege shared-hosting account to gain root-level server control and bypass tenant isolation controls including CloudLinux CageFS. Root access would let attackers access other hosted sites, steal databases and credentials, deploy phishing pages, and install backdoors. Administrators are urged to upgrade to 6.3.7 immediately via lsup.sh and to review privileged account activity, cron jobs, SSH keys, and system binaries; no CVE identifier was published.
