jsPDF Affected by Client-Side/Server-Side Denial of Service via Malicious GIF Dimensions
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
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.
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-67pg-wm7f-q7fj can be triaged on real exposure rather than presence alone.
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.
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.
To exploit this flaw, an attacker must be able to process a specially crafted GIF file with an application using the addImage or html methods. This issue can cause the application to allocate an excessive amount of memory, eventually resulting in a denial of service with no other security impact. Due to this reason,…
