CVE-2018-1131

HIGH

CVE-2018-1131 is a high-severity (CVSS 8.8) CWE-349 vulnerability in org.infinispan:infinispan-core. O3 Security confirms whether CVE-2018-1131 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Infinispan permits improper deserialization of trusted data via XML and JSON transcoders under certain server configurations. A user with authenticated access to the server could send a malicious object to a cache configured to accept certain types of objects, achieving code execution and possible further attacks. Versions 9.0.3.Final, 9.1.7.Final, 8.2.10.Final, 9.2.2.Final, 9.3.0.Alpha1 are believed to be affected.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.infinispan:infinispan-core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    No patched version of org.infinispan:infinispan-core has shipped for CVE-2018-1131 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether CVE-2018-1131 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to CVE-2018-1131. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
