GHSA-67pg-wm7f-q7fj
GHSA-67pg-wm7f-q7fj is a Uncontrolled Resource Consumption vulnerability in jspdf. O3 Security confirms whether GHSA-67pg-wm7f-q7fj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

jspdfnpmDescription
Impact
User control of the first argument of the addImage method results in denial of service.
If given the possibility to pass unsanitized image data or URLs to the addImage method, a user can provide a harmful GIF file that results in out of memory errors and denial of service. Harmful GIF files have large width and/or height entries in their headers, wich lead to excessive memory allocation.
Other affected methods are: html.
Example attack vector:
import { jsPDF } from "jspdf"
// malicious GIF image data with large width/height headers
const payload = ...
const doc = new jsPDF();
doc.addImage(payload, "GIF", 0, 0, 100, 100);
Patches
The vulnerability has been fixed in jsPDF 4.1.1. Upgrade to jspdf@>=4.2.0.
Workarounds
Sanitize image data or URLs before passing it to the addImage method or one of the other affected methods.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for jspdf. 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 jspdf to 4.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-67pg-wm7f-q7fj 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-67pg-wm7f-q7fj 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-67pg-wm7f-q7fj. 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-67pg-wm7f-q7fj in your dependencies?
O3 detects GHSA-67pg-wm7f-q7fj across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
