How severe is CVE-2018-1335?

CVE-2018-1335 has a CVSS score of 8.1/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2018-1335?

CVE-2018-1335 affects the following packages: org.apache.tika:tika-core (Maven). Ecosystems affected: Maven.

How do I fix CVE-2018-1335?

Update org.apache.tika:tika-core to 1.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1335 is resolved across your whole dependency graph.

How do I detect CVE-2018-1335 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.tika:tika-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.

How do I mitigate CVE-2018-1335 if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against CVE-2018-1335?

O3 pinpoints whether CVE-2018-1335 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2018-1335 actively exploited in the wild?

Yes. There are 8 known exploit references for CVE-2018-1335, including 2 documented proof-of-concept exploits 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-2018-1335?

CVE-2018-1335 has an EPSS (Exploit Prediction Scoring System) score of 94.0%, 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.

Is there exploit tooling available for CVE-2018-1335?

A Nuclei detection template exists for CVE-2018-1335, meaning automated scanners can fingerprint it. 2 Metasploit modules reference CVE-2018-1335, which lowers the barrier to weaponization. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2018-1335 published, and has it been updated?

CVE-2018-1335 was published on April 25, 2018 and was last updated on July 8, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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

From Apache Tika versions 1.7 to 1.17, clients could send carefully crafted headers to tika-server that could be used to inject commands into the command line of the server running tika-server. This vulnerability only affects those running tika-server on a server that is open to untrusted clients. The mitigation is to upgrade to Tika 1.18.
