How do I fix GHSA-372q-33vh-8mpc?

Update org.apache.tomcat:tomcat to 9.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-372q-33vh-8mpc is resolved across your whole dependency graph.

How do I detect GHSA-372q-33vh-8mpc 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 GHSA-372q-33vh-8mpc 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.

Is GHSA-372q-33vh-8mpc actively exploited in the wild?

No public exploit code has been indexed for GHSA-372q-33vh-8mpc 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.

Description

As part of the fix for bug 61201, the documentation for Apache Tomcat 9.0.0.M22 to 9.0.1, 8.5.16 to 8.5.23, 8.0.45 to 8.0.47 and 7.0.79 to 7.0.82 included an updated description of the search algorithm used by the CGI Servlet to identify which script to execute. The update was not correct. As a result, some scripts may have failed to execute as expected and other scripts may have been executed unexpectedly. Note that the behaviour of the CGI servlet has remained unchanged in this regard. It is only the documentation of the behaviour that was wrong and has been corrected.
