• CVE-2024-32656: 0.24% estimated exploitation activity in the next 30 days; percentile 15.67 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact We have identified a local privilege escalation vulnerability in Ant Media Server which allows any unprivileged operating system user account to escalate privileges to the root user account on the system. This vulnerability arises from Ant Media Server running with Java Management Extensions (JMX) enabled and authentication disabled on localhost on port 5599/TCP. This vulnerability is nearly identical to the local privilege escalation vulnerability CVE-2023-26269 identified in Apache James. Any unprivileged operating system user can connect to the JMX service running on port 5599/TCP on localhost and leverage the MLet Bean within JMX to load a remote MBean from an attacker-controlled server. This allows an attacker to execute arbitrary code within the Java process run by Ant Media Server and execute code within the context of the “antmedia” service account on the system.

# Patch Next advisory brief: CVE-2024-32656

Advisory: Ant Media Server vulnerable to a local privilege escalation
IDs: CVE-2024-32656, GHSA-qwhw-hh9j-54f5
Record: https://patchnext.com/advisories/cve-2024-32656 (revision 1, source checked 26 Oct 2026, 16:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: io.antmedia:ant-media-server 2.9.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven io.antmedia:ant-media-server: affected >= 2.6.0, < 2.9.0; fixed in 2.9.0

## Suggested inspection (read-only)
- Maven io.antmedia:ant-media-server: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on io.antmedia:ant-media-server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-qwhw-hh9j-54f5 (GitHub-reviewed advisory GHSA-qwhw-hh9j-54f5 lists affected ranges: Maven io.antmedia:ant-media-server >=2.6.0 <2.9.0)
