Which packages are affected by CVE-2016-0782?

CVE-2016-0782 affects the following packages: org.apache.activemq:activemq-client (Maven), org.apache.activemq:activemq-client (Maven), org.apache.activemq:activemq-client (Maven). Ecosystems affected: Maven.

How do I fix CVE-2016-0782?

Update org.apache.activemq:activemq-client to 5.11.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2016-0782 is resolved across your whole dependency graph.

How do I detect CVE-2016-0782 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.activemq:activemq-client, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2016-0782 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2016-0782 actively exploited in the wild?

No public exploit code has been indexed for CVE-2016-0782 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2016-0782?

CVE-2016-0782 has an EPSS (Exploit Prediction Scoring System) score of 6.1%, placing it in the 93th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2016-0782?

Description

The administration web console in Apache ActiveMQ 5.x before 5.11.4, 5.12.x before 5.12.3, and 5.13.x before 5.13.2 allows remote authenticated users to conduct cross-site scripting (XSS) attacks and consequently obtain sensitive information from a Java memory dump via vectors related to creating a queue.
