Description
Allocation of resources for multipart headers with insufficient limits enabled a DoS vulnerability in Apache Commons FileUpload.
This issue affects Apache Commons FileUpload: from 1.0 before 1.6; from 2.0.0-M1 before 2.0.0-M4.
Users are recommended to upgrade to versions 1.6 or 2.0.0-M4, which fix the issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for commons-fileupload:commons-fileupload, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update commons-fileupload:commons-fileupload to 1.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vv7r-c36w-3prj is resolved across your whole dependency graph.
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vv7r-c36w-3prj can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vv7r-c36w-3prj. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
