cPanel Urges Users to Patch ConfigServer Firewall Remote Code Execution Flaw

cPanel urges administrators to patch CVE-2026-65638, a flaw letting unauthenticated attackers run commands through ConfigServer Firewall's MESSENGER service; update to CSF 16.30.

CVE-2026-65638 in ConfigServer Security & Firewall (CSF) 14.00–16.29 allows unauthenticated remote attackers to execute arbitrary commands via the MESSENGER service, which is exposed only when MESSENGER is enabled and a reCAPTCHA secret has been configured. Exploitation yields command execution under the unprivileged CSF service account, providing a foothold for reconnaissance, data access, or lateral movement on internet-facing cPanel/WHM hosting infrastructure. CSF 16.30 or later fixes the issue; disabling MESSENGER in /etc/csf/csf.conf and restarting csf and lfd is a temporary mitigation.

12 Best Kubernetes Security Tools Compared (2026): Features & Pricing

GBHackers compares 12 Kubernetes security vendors including Sysdig, Wiz, Aqua, and Cisco Isovalent on features, pricing units, and procurement strategy.

GBHackers publishes a 2026 buying guide comparing 12 Kubernetes security vendors including Sysdig, Wiz, Aqua Security, SUSE NeuVector, Snyk, Cisco Isovalent, Palo Alto Networks, Fairwinds, Red Hat ACS, and Tigera. It argues CNCF-grade open source (Kubescape, Falco, Trivy, Calico, Cilium/Tetragon) provides free posture, runtime, and network policy coverage that resets price negotiations. Cisco's acquisition of Isovalent places the eBPF data plane under a networking giant, while the paid market focuses on multi-cluster policy, enforcement, and support. The piece emphasizes that pricing units (workload, node, cluster, developer, credits) heavily influence contract costs.

Harnessing LLMs for Automating BOLA Detection

Unit 42's BOLABuster methodology uses LLMs to automate detection of broken object-level authorization vulnerabilities, uncovering flaws in Grafana, Harbor, and Easy!Appointments.

Palo Alto Unit 42 details BOLABuster, a methodology combining large language models with heuristics to automate detection of broken object-level authorization (BOLA) flaws, which traditional fuzzing and static analysis struggle to find. The approach uses LLM reasoning to understand application logic, map endpoint dependency relationships, and generate and interpret test cases. It found CVE-2024-1313 in Grafana, CVE-2024-22278 in Harbor, and 15 CVEs in Easy!Appointments. The team is continuing to hunt for BOLAs in open-source and internal projects.

Identifying a BOLA Vulnerability in Harbor, a Cloud

Unit 42 found a BOLA flaw, CVE-2024-22278 (CVSS 6.4), letting Maintainers improperly alter Harbor project metadata; fixed in versions 2.9.5, 2.10.3, and 2.11.0.

Unit 42 researchers identified a broken object-level authorization flaw, CVE-2024-22278, in Harbor, a CNCF-graduated cloud-native container registry with 1.8 million downloads. The flaw (CVSS 6.4) lets users with the Maintainer role create, update, and delete project metadata, actions reserved for ProjectAdmin, risking data exposure, integrity compromise, and circumvention of vulnerability scanning. Harbor patched the issue in versions 2.9.5, 2.10.3, and 2.11.0. The finding came from Unit 42's automated BOLA detection tool built on generative AI.
