GHSA-rj3r-r7hh-jxfq is a high-severity (CVSS 7.5) CWE-770 vulnerability in pdfmake. O3 Security confirms whether GHSA-rj3r-r7hh-jxfq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
pdfmake is vulnerable to Throttling via repeatedly redirecting URL in file embedding
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
pdfmakenpmDescription
Versions of the package pdfmake from 0.3.0-beta.1 to before 0.3.0-beta.17 are vulnerable to Allocation of Resources Without Limits or Throttling via repeatedly redirect URL in file embedding. An attacker can cause the application to crash or become unresponsive by providing crafted input that triggers this condition.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | pdfmake | ≥ 0.3.0-beta.1&&< 0.3.0-beta.17 | 0.3.0-beta.17 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pdfmake. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update pdfmake to 0.3.0-beta.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rj3r-r7hh-jxfq 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 pinpoints whether GHSA-rj3r-r7hh-jxfq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-rj3r-r7hh-jxfq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-rj3r-r7hh-jxfq in your dependencies?
O3 detects GHSA-rj3r-r7hh-jxfq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
