CVE-2023-40315 Aug 17, 20:15 Maven HIGH POC PATCH Act Now

In OpenMNS Horizon 31.0.8 and versions earlier than 32.0.2 and related Meridian versions, any user that has the ROLE_FILESYSTEM_EDITOR can easily escalate their privileges to ROLE_ADMIN or any other. Rated high severity (CVSS 8.0), this vulnerability is low attack complexity. This Incorrect Authorization vulnerability could allow attackers to bypass authorization checks to access restricted resources.

CVE-2023-0872 Aug 14, 18:15 Maven HIGH POC PATCH Act Now

The Horizon REST API includes a users endpoint in OpenMNS Horizon 31.0.8 and versions earlier than 32.0.2 on multiple platforms is vulnerable to elevation of privilege. Rated high severity (CVSS 8.0), this vulnerability is low attack complexity. This Improper Privilege Management vulnerability could allow attackers to escalate privileges to gain unauthorized elevated access.

CVE-2026-19182 Aug 13, 04:50 MEDIUM PATCH This Month

Incorrect authorization in OpenNMS Meridian and Horizon's v2 Alarm REST API allows any authenticated ROLE_REST user to acknowledge, escalate, or clear alarms attributed to arbitrary usernames, effectively forging audit records without holding delegation privileges. An inverted boolean condition in AlarmRestService.java - `!StringUtils.isNotBlank(ackUser)` instead of `StringUtils.isNotBlank(ackUser)` - renders the credential delegation check dead code for any non-blank username supplied in the request. Users simultaneously holding ROLE_REST and ROLE_READONLY can additionally bypass the read-only restriction to modify alarm state. No public exploit exists and the vulnerability is absent from CISA KEV; vendor-confirmed patches are available via OpenNMS GitHub PR #8755.

CVE-2026-19135 Aug 13, 04:47 MEDIUM PATCH NEWS This Month

JEXL expression sandbox bypass in OpenNMS Meridian and Horizon allows a low-privileged authenticated user to load arbitrary Java classes on the server via the Measurements REST API, enabling confidentiality disclosure and integrity compromise. The flaw stems from incorrect authorization logic in OnmsJexlUberspect that checked method calls on a whitelisted class object against the whitelisted class rather than against java.lang.Class itself, allowing reflection chains such as table.getClass().forName('java.lang.Runtime') to escape the sandbox. No public exploit or CISA KEV listing has been identified at time of analysis, but the upstream GitHub PR provides regression tests that precisely document the bypass technique.

CVE-2026-55748 Jun 17, 14:12 PyPI MEDIUM This Month

OpenStack Horizon before 25.7.4 embeds project names unsanitized into generated OpenStack RC shell scripts, enabling OS command injection when a victim user downloads and sources that script locally. An attacker with sufficient privileges to create or control a project name can insert shell metacharacters (e.g., backtick sequences, command substitution syntax) that execute arbitrary commands in the victim's local shell environment upon RC file execution. No public exploit code or CISA KEV listing exists at time of analysis, though the underlying CWE-78 class is well-understood; notably, the OpenStack project itself characterizes this as a security hardening opportunity rather than a traditional vulnerability, reflecting a disputed severity framing.
