| CVE-2023-39001 | CRITICAL | 9.8 | Aug 9, 2023 | A command injection vulnerability in the component diag_backup.php of OPNsense Community Edition before 23.7 and Business Edition before 23.4.2 allows attackers to execute arbitrary commands via a crafted backup configuration file. |
| CVE-2023-39007 | CRITICAL | 9.6 | Aug 9, 2023 | /ui/cron/item/open in the Cron component of OPNsense Community Edition before 23.7 and Business Edition before 23.4.2 allows XSS via openAction in app/controllers/OPNsense/Cron/ItemController.php. |
| CVE-2026-45158 | CRITICAL | 9.1 | May 13, 2026 | OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.8, unsanitized user input is passed to the DHCP configuration of the configured interface, which is processed by a shell script, allowing remote code execution as root on the underlying operating system. This vulnerability is fixed in 26.1.8. |
| CVE-2026-44194 | CRITICAL | 9.1 | May 13, 2026 | OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.8, an authenticated Remote Code Execution (RCE) vulnerability in the OPNsense core allows a user with user-management privileges to execute arbitrary system commands as root. An attacker can bypass input validation by formatting their malicious payload as a compliant email address, allowing shell commands to reach the underlying operating system. The flaw exists in the local user synchronization flow, within core/src/opnsen |
| CVE-2026-44193 | CRITICAL | 9.1 | May 13, 2026 | OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.7, the XMLRPC method opnsense.restore_config_section fails to sanitize user supplied input leading to Remote Code Execution. This vulnerability is fixed in 26.1.7. |
| CVE-2025-50989 | CRITICAL | 9.1 | Aug 27, 2025 | OPNsense before 25.1.8 contains an authenticated command injection vulnerability in its Bridge Interface Edit endpoint (interfaces_bridge_edit.php). The span POST parameter is concatenated into a system-level command without proper sanitization or escaping, allowing an administrator to inject arbitrary shell operators and payloads. Successful exploitation results in remote code execution with the privileges of the web service (typically root), potentially leading to full system compromise or lat |
| CVE-2026-34578 | HIGH | 8.2 | Apr 9, 2026 | OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.6, OPNsense's LDAP authentication connector passes the login username directly into an LDAP search filter without calling ldap_escape(). An unauthenticated attacker can inject LDAP filter metacharacters into the username field of the WebGUI login page to enumerate valid LDAP usernames in the configured directory. When the LDAP server configuration includes an Extended Query to restrict login to members of a specific group, |
| CVE-2023-39005 | HIGH | 7.5 | Aug 9, 2023 | Insecure permissions exist for configd.socket in OPNsense Community Edition before 23.7 and Business Edition before 23.4.2. |
| CVE-2023-39003 | HIGH | 7.5 | Aug 9, 2023 | OPNsense Community Edition before 23.7 and Business Edition before 23.4.2 was discovered to contain insecure permissions in the directory /tmp. |
| CVE-2023-38997 | HIGH | 7.2 | Aug 9, 2023 | A directory traversal vulnerability in the Captive Portal templates of OPNsense Community Edition before 23.7 and Business Edition before 23.4.2 allows attackers to execute arbitrary system commands as root via a crafted ZIP archive. |

| CVE-2026-30868 | MEDIUM | 6.3 | Mar 11, 2026 | OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.4, multiple OPNsense MVC API endpoints perform state‑changing operations but are accessible via HTTP GET requests without CSRF protection. The framework CSRF validation in ApiControllerBase only applies to POST/PUT/DELETE methods, allowing authenticated GET requests to bypass CSRF verification. As a result, a malicious website can trigger privileged backend actions when visited by an authenticated user, causing unintended s |
| CVE-2023-39002 | MEDIUM | 6.1 | Aug 9, 2023 | A cross-site scripting (XSS) vulnerability in the act parameter of system_certmanager.php in OPNsense Community Edition before 23.7 and Business Edition before 23.4.2 allows attackers to execute arbitrary web scripts or HTML via a crafted payload. |
