Which packages are affected by CVE-2018-1999026?

CVE-2018-1999026 affects the following packages: de.tracetronic.jenkins.plugins:ecutest (Maven). Ecosystems affected: Maven.

How do I fix CVE-2018-1999026?

Update de.tracetronic.jenkins.plugins:ecutest to 2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1999026 is resolved across your whole dependency graph.

How do I detect CVE-2018-1999026 in my Maven dependencies?

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

How do I mitigate CVE-2018-1999026 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is CVE-2018-1999026 actively exploited in the wild?

No public exploit code has been indexed for CVE-2018-1999026 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-2018-1999026?

CVE-2018-1999026 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 58th 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.
