Which packages are affected by CVE-2016-0709?

CVE-2016-0709 affects the following packages: org.apache.portals.jetspeed-2:jetspeed (Maven). Ecosystems affected: Maven.

How do I fix CVE-2016-0709?

Update org.apache.portals.jetspeed-2:jetspeed to 2.3.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2016-0709 is resolved across your whole dependency graph.

How do I detect CVE-2016-0709 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.portals.jetspeed-2:jetspeed, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2016-0709 if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is CVE-2016-0709 actively exploited in the wild?

Yes. There are 5 known exploit references for CVE-2016-0709, including 1 documented proof-of-concept exploit on Exploit-DB and 4 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2016-0709?

CVE-2016-0709 has an EPSS (Exploit Prediction Scoring System) score of 77.5%, placing it in the 100th 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. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.
