No CVSS score has been assigned to CVE-2011-1088 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2011-1088?

CVE-2011-1088 affects the following packages: org.apache.tomcat:tomcat (Maven). Ecosystems affected: Maven.

How do I fix CVE-2011-1088?

Update org.apache.tomcat:tomcat to 7.0.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2011-1088 is resolved across your whole dependency graph.

How do I detect CVE-2011-1088 in my Maven dependencies?

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

How do I mitigate CVE-2011-1088 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-2011-1088?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2011-1088 can be triaged on real exposure rather than presence alone.

Is CVE-2011-1088 actively exploited in the wild?

No public exploit code has been indexed for CVE-2011-1088 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-2011-1088?

CVE-2011-1088 has an EPSS (Exploit Prediction Scoring System) score of 6.5%, 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.

When was CVE-2011-1088 published, and has it been updated?

CVE-2011-1088 was published on May 14, 2022 and was last updated on February 27, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
