Netgate Security Advisories + NVD
Netgate maintains a dedicated Security Advisory index for pfSense (docs.netgate.com/advisories), but pfSense CVEs are assigned by MITRE and third-party researchers rather than a Netgate CNA — so VulniPulse ingests them from NVD (keyword-filtered to pfSense, dropped unless a pfSense/Netgate product is named) and links back to the Netgate advisory or pfSense reference. Covers pfSense CE (Community Edition) and pfSense Plus — a firewall/router at the network edge where a bug is directly internet-exposed.
Latest pfSense advisories
Medium [CVE-2022-21132] Directory traversal vulnerability in pfSense-pkg-WireGuard pfSense-pkg-WireGuard 0.1.5 versions prior to 0.1.5_4 and…
Directory traversal vulnerability in pfSense-pkg-WireGuard pfSense-pkg-WireGuard 0.1.5 versions prior to 0.1.5_4 and pfSense-pkg-WireGuard 0.1.6 versions prior to 0.1.6_1 allows a remote authenticated attacker to lead a pfSense user to view a file outside the public folder.
High [CVE-2021-41282] pfSense: diag_routes.php in pfSense 2.5.2 allows sed data injection.
diag_routes.php in pfSense 2.5.2 allows sed data injection. Authenticated users are intended to be able to view data about the routes set in the firewall. The data is retrieved by executing the netstat utility, and then its output is parsed via the sed utility. Although the common protection mechanisms against command injection (i.e., the usage of the escapeshellarg function for the arguments) are used, it is still possible to inject sed-specific code and write an arbitrary file in an arbitrary location.
Medium [CVE-2022-23993] /usr/local/www/pkg.php in pfSense CE before 2.6.0 and pfSense Plus before 22.01 uses $_REQUEST['pkg_filter'] in a PHP echo call
/usr/local/www/pkg.php in pfSense CE before 2.6.0 and pfSense Plus before 22.01 uses $_REQUEST['pkg_filter'] in a PHP echo call, causing XSS.
Medium [CVE-2020-19203] pfSense: authenticated Cross-Site Scripting (XSS) vulnerability was found in widgets/widgets/wake_on_lan_widget.php, a component of…
An authenticated Cross-Site Scripting (XSS) vulnerability was found in widgets/widgets/wake_on_lan_widget.php, a component of the pfSense software WebGUI, on version 2.4.4-p2 and earlier. The widget did not encode the descr (description) parameter of wake-on-LAN entries in its output, leading to a possible stored XSS.
Medium [CVE-2020-19201] Stored Cross-Site Scripting (XSS) vulnerability was found in status_filter_reload.php, a page in the pfSense software WebGUI…
A Stored Cross-Site Scripting (XSS) vulnerability was found in status_filter_reload.php, a page in the pfSense software WebGUI, on Netgate pfSense version 2.4.4-p2 and earlier. The page did not encode output from the filter reload process, and a stored XSS was possible via the descr (description) parameter on NAT rules.
Medium [CVE-2020-26693] stored cross-site scripting (XSS) vulnerability was discovered in pfSense 2.4.5-p1 which
A stored cross-site scripting (XSS) vulnerability was discovered in pfSense 2.4.5-p1 which allows an authenticated attacker to execute arbitrary web scripts via exploitation of the load_balancer_monitor.php function.
Medium [CVE-2021-27933] pfSense: pfSense 2.5.0 allows XSS via the services_wol_edit.php Description field.
pfSense 2.5.0 allows XSS via the services_wol_edit.php Description field.
Medium [CVE-2020-11457] pfSense before 2.4.5 has stored XSS in system_usermanager_addprivs.php in the WebGUI
pfSense before 2.4.5 has stored XSS in system_usermanager_addprivs.php in the WebGUI via the descr parameter (aka full name) of a user.
Medium [CVE-2019-18667] /usr/local/www/freeradius_view_config.php in the freeradius3 package before 0.15.7_3 for pfSense on FreeBSD
/usr/local/www/freeradius_view_config.php in the freeradius3 package before 0.15.7_3 for pfSense on FreeBSD allows a user with an XSS payload as password or username to execute arbitrary javascript code on a victim browser.
Critical [CVE-2019-16915] pfSense: issue was discovered in pfSense through 2.4.4-p3.
An issue was discovered in pfSense through 2.4.4-p3. widgets/widgets/picture.widget.php uses the widgetkey parameter directly without sanitization (e.g., a basename call) for a pathname to file_get_contents or file_put_contents.
High [CVE-2019-16667] diag_command.php in pfSense 2.4.4-p3 allows CSRF
diag_command.php in pfSense 2.4.4-p3 allows CSRF via the txtCommand or txtRecallBuffer field, as demonstrated by executing OS commands. This occurs because csrf_callback() produces a "CSRF token expired" error and a Try Again button when a CSRF token is missing.
Medium [CVE-2019-16914] pfSense: XSS issue was discovered in pfSense through 2.4.4-p3.
An XSS issue was discovered in pfSense through 2.4.4-p3. In services_captiveportal_mac.php, the username and delmac parameters are displayed without sanitization.

pfSense through 2.3.4 through 2.4.4-p3 allows Remote Code Injection via a methodCall XML document with a pfsense.exec_php call containing shell metacharacters in a parameter value.
Medium [CVE-2019-12949] In pfSense 2.4.4-p2 and 2.4.4-p3, if it is possible to trick an authenticated administrator into clicking on a button on a…
In pfSense 2.4.4-p2 and 2.4.4-p3, if it is possible to trick an authenticated administrator into clicking on a button on a phishing page, an attacker can leverage XSS to upload arbitrary executable code, via diag_command.php and rrd_fetch_json.php (timePeriod parameter), to a server. Then, the remote attacker can run any command with root privileges on that server.
Critical [CVE-2019-12585] Apcupsd 0.3.91_5, as used in pfSense through 2.4.4-RELEASE-p3 and other products, has an Arbitrary Command Execution issue in…
Apcupsd 0.3.91_5, as used in pfSense through 2.4.4-RELEASE-p3 and other products, has an Arbitrary Command Execution issue in apcupsd_status.php.
Medium [CVE-2019-12584] Apcupsd 0.3.91_5, as used in pfSense through 2.4.4-RELEASE-p3 and other products, has an XSS issue in apcupsd_status.php

Incorrect access control in the WebUI in OPNsense before version 19.1.8, and pfsense before 2.4.4-p3 allows remote authenticated users to escalate privileges to administrator via a specially crafted request.
High [CVE-2018-20799] In pfSense 2.4.4_1, blocking of source IP addresses on the basis of failed HTTPS authentication is inconsistent with blocking of…
In pfSense 2.4.4_1, blocking of source IP addresses on the basis of failed HTTPS authentication is inconsistent with blocking of source IP addresses on the basis of failed SSH authentication (the behavior does not match the sshguard documentation), which might make it easier for attackers to bypass intended access restrictions.
High [CVE-2018-20798] The expiretable configuration in pfSense 2.4.4_1 establishes block durations that are incompatible with the block durations…
The expiretable configuration in pfSense 2.4.4_1 establishes block durations that are incompatible with the block durations implemented by sshguard, which might make it easier for attackers to bypass intended access restrictions.
