Palo Alto Networks Patches PAN-OS Command Injection CVE-2026-0273 Across All Active Branches
Palo Alto Networks has patched CVE-2026-0273, a command injection vulnerability in the PAN-OS web management interface that allows authenticated administrators to execute arbitrary OS commands on the firewall. The vulnerability affects PAN-OS versions 10.1 through 11.2 and all active GlobalProtect gateway configurations. Updates are available across all supported branches.
CVE-2026-46243: 19-Year-Old Linux CIFS Kernel Flaw Grants Unprivileged Local Root Across Major Distributions
A long-latent vulnerability in the Linux kernel's CIFS filesystem subsystem allows any unprivileged local user to forge a upcall key and escalate directly to root. Patched kernels reached distribution repositories on 2–3 June; Red Hat, AlmaLinux, Rocky Linux, and CloudLinux all issued security advisories on 3 June. A public proof-of-concept exists.
SonicWall CVE-2026-0204 — Authentication Bypass in SSLVPN Allows Unauthenticated Network Access
SonicWall has disclosed CVE-2026-0204, an authentication bypass vulnerability in the SonicWall SSLVPN product that allows a remote attacker to bypass VPN authentication and gain access to the protected network without valid credentials. SonicWall SSLVPN appliances are widely deployed as enterprise and SMB VPN concentrators. Patch available — update immediately.
ProFTPD CVE-2026-42167 — Authentication Bypass Leading to Remote Code Execution
A vulnerability in ProFTPD — one of the most widely deployed open-source FTP server implementations — allows a remote unauthenticated attacker to bypass authentication controls and achieve code execution on the server. CVE-2026-42167 affects ProFTPD versions prior to 1.3.9a. FTP servers are frequently forgotten in patch management programmes; administrators should verify ProFTPD version and apply the update.
cPanel/WHM Patches Three New Vulnerabilities Including CVSS 8.8 Code Execution and Privilege Escalation
cPanel has released security updates addressing three new vulnerabilities distinct from the previously covered CVE-2026-41940 zero-day: CVE-2026-29202 (CVSS 8.8, Perl code execution), CVE-2026-29203 (CVSS 8.8, symlink-based privilege escalation), and CVE-2026-29201 (CVSS 4.3, arbitrary file read). Web hosting providers running cPanel/WHM should apply the updates urgently given the platform's current elevated threat posture following mass exploitation in May 2026.
Wireshark CVE-2026-5656 — Remote Code Execution via Malicious PCAP File, Update to 4.4.6
A code execution vulnerability in Wireshark's PCAP/PCAPNG file parser allows a malicious capture file to trigger arbitrary code execution when opened by an analyst. CVE-2026-5656 affects all Wireshark versions prior to 4.4.6 across Windows, macOS, and Linux. The attack vector is especially concerning for security teams that open externally-sourced capture files during incident response or threat hunting — update Wireshark to 4.4.6 immediately.
OpenSSH 10.3 Patches Shell Metacharacter Injection CVE-2026-35386 in Non-Default scp Configurations
OpenSSH 10.3, released April 26, addresses CVE-2026-35386, a shell metacharacter injection flaw in the scp client that can result in unintended remote command execution when transferring files from attacker-controlled servers. While exploitation requires non-default configuration, scp is still widely used in automated backup and deployment pipelines and should be updated promptly.
Linux Kernel Netfilter Vulnerability Batch: CVE-2026-31414 and Cluster Require Prompt Patching
A cluster of Linux kernel vulnerabilities in the netfilter subsystem — led by CVE-2026-31414 — has been patched across stable kernel branches, affecting versions 6.1 through 6.10. The flaws span NULL pointer dereferences and connection tracking weaknesses that can cause privilege escalation or denial of service. Enterprise Linux distributions are releasing updates; unmanaged servers and container hosts running custom kernel builds require manual attention.
Citrix CVE-2026-3055 Confirmed Exploited — CISA KEV Addition Triggers Mandatory Patch Deadline
CISA added CVE-2026-3055 to its Known Exploited Vulnerabilities catalogue on 30 March, confirming active exploitation of the critical Citrix NetScaler memory overread vulnerability disclosed the previous week. NetScaler appliances configured as SAML Identity Providers are leaking session tokens from memory, allowing attackers to impersonate users without credentials. Organisations must patch immediately.
F5 BIG-IP APM Vulnerability Reclassified as Critical RCE — CISA Mandates Three-Day Patch Window
A vulnerability in F5 BIG-IP Access Policy Manager initially classed as denial-of-service has been reclassified as critical remote code execution with CVSS 9.8 after active exploitation was confirmed. CISA added CVE-2025-53521 to its Known Exploited Vulnerabilities catalogue on 27 March and set a three-day patch deadline for federal agencies. All organisations running BIG-IP APM should treat this as an emergency.
