| CVE-2026-108715 | 1 Librenms | 1 Librenms | 2026-10-13 | 4.3 Medium |
| LibreNMS through 26.9.1.1 contains an authorization bypass vulnerability in includes/html/graphs/smokeping/auth.inc.php that checks the src probe device instead of the rendered target device. Restricted users permitted on a probe device can request smokeping_in or smokeping_out graphs with arbitrary device ids to view latency data and enumerate device names. | ||||
| CVE-2026-109357 | 1 Librenms | 1 Librenms | 2026-10-12 | 8.1 High |
| LibreNMS before 26.9.0 contains an LDAP filter injection in ldap-authorization and ad-authorization modes because usernames are inserted unescaped into LDAP search filters and authentication only checks user existence. When REMOTE_USER is not forwarded, unauthenticated attackers can send a wildcard username via HTTP Basic Authorization (PHP_AUTH_USER) to match all users and groups and gain admin access. | ||||
| CVE-2026-109356 | 1 Librenms | 1 Librenms | 2026-10-12 | 4.3 Medium |
| LibreNMS before 26.9.0 contains a missing authorization vulnerability in PortsController::purge that allows global-read users to physically delete ports without delete privileges. Attackers with read-only accounts can send DELETE requests to /ports/purge, using purge=all to irreversibly erase every deleted port on all visible devices. | ||||

| CVE-2026-86426 | 1 Librenms | 1 Librenms | 2026-09-18 | 9.8 Critical |
| LibreNMS before 26.8.0 contains an authentication bypass vulnerability in the REST API that allows unauthenticated attackers to access protected endpoints by sending numeric values instead of string tokens. Attackers can exploit MySQL type coercion by sending small integers like 0 through 9 to match token hashes, gaining access to API functionality including device credentials and administrative features that enable remote code execution through alert templates. | ||||
| CVE-2020-15875 | 1 Librenms | 1 Librenms | 2026-09-15 | 5 Medium |
| An issue was discovered in LibreNMS 1.65. A remote authenticated attacker with normal privileges can extract all the information from the LibreNMS database via a SQL injection in the searchPhrase parameter in the /ajax_table.php API endpoint. This affects as-selection.inc.php, edit-ports.inc.php, alertlog-stats.inc.php, alerts.inc.php, eventlog.inc.php, inventory.inc.php, ix-list.inc.php, ix-peers.inc.php, mempool-edit.inc.php, mempool.inc.php, poll-log.inc.php, processor-edit.inc.php, processor.inc.php, routing-edit.inc.php, sensors-common.inc.php, storage-edit.inc.php, storage.inc.php, and toner.inc.php (in includes/html/table). NOTE: some sources refer to this as CVE-2020-15876, but CVE-2020-15875 is the only correct CVE ID. | ||||
| CVE-2026-86427 | 1 Librenms | 1 Librenms | 2026-09-10 | 8.8 High |
| LibreNMS before 26.8.0 contains an argument injection vulnerability in the graph_title parameter that allows authenticated attackers to inject arbitrary rrdtool arguments by breaking out of double-quote escaping. Attackers can inject DEF and LINE arguments to read RRD files from unauthorized devices, or use newline injection to execute arbitrary rrdtool commands, bypassing per-device authorization checks. | ||||
| CVE-2026-84189 | 1 Librenms | 1 Librenms | 2026-09-04 | 8.1 High |
| LibreNMS through 26.4.0 renders JSON fields (name, ip, model, author, commit message) returned by the admin-configurable Oxidized integration URL (oxidized.url) into the device showconfig page without applying htmlspecialchars(). An administrator who points the Oxidized URL at an attacker-controlled server (SSRF) can cause it to return malicious JSON, resulting in stored/persistent cross-site scripting affecting all users who view any device's showconfig tab. Fixed in 26.7.0. | ||||
| CVE-2026-84194 | 1 Librenms | 1 Librenms | 2026-09-04 | N/A |
| LibreNMS versions >= 23.10.0 and < 26.2.0 (fixed in 26.4.0) contain an authenticated OS command injection vulnerability in libvirt discovery. When libvirt support is enabled (enable_libvirt=true), the device hostname ($this->getDevice()->hostname) is concatenated into shell commands (ssh, virsh list/dumpxml/domstate) in VminfoLibvirt.php and passed to exec() without escapeshellarg() or argument separation. An authenticated admin can set a crafted device hostname to inject arbitrary OS commands, leading to remote code execution in the discovery worker context. | ||||
| CVE-2026-84193 | 1 Librenms | 1 Librenms | 2026-09-02 | N/A |
| LibreNMS through 26.2.0 contains a stored cross-site scripting vulnerability in legacy PHP template pages that render unescaped SNMP-sourced data fields including BGP peer descriptions, VRF names, process information, and SLA tags. Attackers with device management access or network access to enroll a rogue SNMP device can inject malicious JavaScript that executes when admins view affected routing and device pages, enabling credential theft and CSRF token exfiltration. | ||||
| CVE-2026-84188 | 1 Librenms | 1 Librenms | 2026-09-02 | 4.8 Medium |
| LibreNMS versions <= 26.4.0 contain a stored cross-site scripting vulnerability in the graph_descr.<graphtype> configuration settings, which are echoed verbatim without HTML escaping in includes/html/pages/graphs.inc.php. An administrator can store a malicious HTML payload that executes in the browser of any authenticated user who views the affected graph type. The issue is fixed in version 26.7.0. | ||||
