OPNsense released version 26.7 for its FreeBSD-based firewall and routing platform, updating major components including a FreeBSD 15.1 development snapshot, OpenVPN 2.7, PHP 8.5, and Python 3.13, alongside IPv6, KEA DHCP, Captive Portal, and outbound NAT changes. The release is notable for patching a critical vulnerability tracked as CVE-2026-57155 and rated 9.9/10.
The flaw affected the GeoIP alias import path exposed through the Web API, where insufficient validation of GeoIP-related file paths or URLs allowed an authenticated administrator to create arbitrary files as root and reach shell command execution paths. Reports said the issue could be abused with directory traversal to write files such as ../../../../../../../../etc/newsyslog.conf.d/zzz_pwn, ultimately enabling root-level remote code execution on affected systems.

FreeBSD released security updates for **22 vulnerabilities** across the operating system, including multiple flaws that could lead to **remote code execution**, **local privilege escalation to root**, **denial of service**, **memory corruption**, and **information disclosure**. The most severe issue, **`CVE-2026-49420`**, affects `libalias`, where improper handling of **RTSP** traffic during NAT processing can allow **remote code execution as root** on systems using **`ipfw` NAT** or **`natd`**. The fixes were shipped in **FreeBSD 15.1-RELEASE-p1**, **15.0-RELEASE-p11**, **14.4-RELEASE-p7**, and **14.3-RELEASE-p16**. Additional patched components include `execve`, **Jail**, **OpenZFS**, **Linuxulator**, **KTLS**, `sound`, `vt`, `ptrace`, IPv6 multicast filtering, `tcp_rack`, `compat32`, `iconv`, and pathname resolution protections such as **`AT_RESOLVE_BENEATH`**, with the advisory noting that **13 of the issues** could enable privilege escalation to root.

Palo Alto Networks disclosed and patched multiple vulnerabilities in **PAN-OS** affecting **PA-Series**, **VM-Series**, and **Panorama**, including `CVE-2026-0273`, an authenticated administrator command injection flaw in the **CLI** and **web management interface** that can allow arbitrary commands to run as **root**. The vendor also fixed `CVE-2026-0272`, an authenticated **CLI privilege escalation** issue, and `CVE-2026-0266`, a **stored XSS** vulnerability in the web interface. A separate issue, `CVE-2026-0269`, can trigger a **denial of service** through crafted tunnel traffic and repeatedly reboot affected firewalls, potentially forcing them into maintenance mode. Affected versions span supported **PAN-OS 12.1, 11.2, 11.1, and 10.2** release trains, while **Cloud NGFW** and **Prisma Access** were reported as unaffected. Palo Alto Networks said it was not aware of active exploitation at disclosure time and urged customers to upgrade promptly, restrict management access to trusted internal IPs, limit CLI exposure, and use hardened jump boxes; for `CVE-2026-0273`, organizations with **Threat Prevention** can also enable dedicated **Threat IDs** to help block exploit attempts when management traffic is inspectable and decrypted.
Jun 29, 2026Palo Alto Networks disclosed **CVE-2026-0300**, a critical `CWE-787` out-of-bounds write in the PAN-OS User-ID Authentication Portal, also known as the Captive Portal, that allows an unauthenticated attacker to achieve remote code execution as **root** on affected **PA-Series** and **VM-Series** firewalls. The flaw was reported as actively exploited in the wild and added to CISA's **Known Exploited Vulnerabilities** catalog, with exploitation observed against portals reachable from untrusted networks or the public internet. Palo Alto said **Prisma Access**, **Cloud NGFW**, and **Panorama** are not affected, while vulnerable PAN-OS branches included 10.2, 11.1, 11.2, and 12.1 below fixed releases. Reporting on observed intrusions said attackers used the firewall access for shellcode injection into `nginx` worker processes, credential extraction, Active Directory enumeration, outbound tunneling with tools such as **EarthWorm** and **ReverseSocks5**, internal pivoting, and anti-forensic log cleanup. Palo Alto began releasing patches in staged waves and urged defenders to disable the Captive Portal if unused or restrict it to trusted IPs and zones, enable available threat-prevention signatures, and treat previously exposed devices as potentially fully compromised by auditing configurations, checking admin accounts and SSH keys, rotating credentials, and monitoring for persistence or suspicious outbound connections.
