Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
min-documentnpmDescription
A vulnerability exists in the 'min-document' package prior to version 2.19.0, stemming from improper handling of namespace operations in the removeAttributeNS method. By processing malicious input involving the proto property, an attacker can manipulate the prototype chain of JavaScript objects, leading to denial of service or arbitrary code execution. This issue arises from insufficient validation of attribute namespace removal operations, allowing unintended modification of critical object prototypes. The vulnerability remains unaddressed in the latest available version.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for min-document, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update min-document to 2.19.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rx8g-88g5-qh64 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-rx8g-88g5-qh64 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-rx8g-88g5-qh64. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
