Which packages are affected by CVE-2007-1355?

CVE-2007-1355 affects the following packages: org.apache.tomcat:jsp-api (Maven), org.apache.tomcat:jsp-api (Maven), org.apache.tomcat:jsp-api (Maven), org.apache.tomcat:jsp-api (Maven), org.apache.tomcat:jsp-api (Maven), org.apache.tomcat:servlet-api (Maven), org.apache.tomcat:servlet-api (Maven), org.apache.tomcat:servlet-api (Maven), and 2 more. Ecosystems affected: Maven.

How do I fix CVE-2007-1355?

Update org.apache.tomcat:jsp-api to 4.1.37 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2007-1355 is resolved across your whole dependency graph.

How do I detect CVE-2007-1355 in my Maven dependencies?

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

How do I mitigate CVE-2007-1355 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2007-1355 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2007-1355, including 1 documented proof-of-concept exploit on Exploit-DB and 1 in-the-wild exploitation 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-2007-1355?

CVE-2007-1355 has an EPSS (Exploit Prediction Scoring System) score of 58.2%, placing it in the 99th 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.

When was CVE-2007-1355 published, and has it been updated?

CVE-2007-1355 was published on May 1, 2022 and was last updated on April 9, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
