Overview of CVE-2024-21484
CVE-2024-21484 jsPDF is a critical flaw in the jsPDF library that allows abuse of PDF generation when untrusted or unsafe data is processed.
Impact varies by implementation, but the jsPDF vulnerability can enable content injection, spoofing, or unintended data exposure in applications that export dynamic inputs to PDF.
Maintainers released a fix and advised all users to upgrade to the latest secure version. If your application ingests user-supplied HTML, text, or data before exporting to PDF, treat the jsPDF vulnerability as a high-priority item.
Official details and patch availability are listed on the NVD and the project’s release page:

The update follows a pattern seen across widely used components, where quick patch cycles are essential to reduce supply chain risk. Related coverage includes NPM supply chain compromise incidents and vendor push patching such as Microsoft zero-day fixes.
Why the jsPDF vulnerability matters
jsPDF is common in browsers and Node.js for on-demand PDF generation. That ubiquity means a single unpatched dependency can enable attacker-controlled content to reach downstream users or sensitive systems.
Because PDF output often intersects billing, reporting, and document workflows, the jsPDF vulnerability can amplify business risk if left unresolved.
Who is affected by the jsPDF vulnerability
Any organization or developer using jsPDF to convert dynamic or user-supplied data into PDFs may be affected. Typical exposure includes:
- Web apps generating PDFs from forms, profiles, or CMS-managed content
- Server-side rendering pipelines assembling PDFs from external data sources
- Internal tooling that automates reporting or exports dashboards to PDF
If uncertain whether jsPDF is present, search repositories and lockfiles, check SBOMs, and run SCA scans to locate the jsPDF vulnerability and transitive usage. For additional context, see recent app-layer vulnerability disclosures.
How to mitigate CVE-2024-21484
To reduce exposure from the jsPDF vulnerability, take these steps:
- Upgrade to the latest jsPDF release that fixes CVE-2024-21484.
- Audit all code paths that render user-controlled data into PDFs; enforce strict validation and sanitization.
- Disable or restrict HTML/rich content features unless sanitized by trusted libraries.
- Harden CI/CD to prevent downgrades and pin patched versions.
Where feasible, perform negative testing with malicious inputs to ensure the jsPDF vulnerability is fully remediated and defenses hold under edge cases.
Where this fits in JavaScript PDF library security
JavaScript PDF library security is inherently complex due to rendering of HTML, images, and templates. Without rigorous controls, libraries that transform dynamic content can become injection or data leakage conduits. The jsPDF vulnerability reinforces the need for defense-in-depth alongside timely patches.
For related patch cycles and urgency across the ecosystem, review Apple security patch fixes and cURL security updates.
Detection and validation steps
Teams addressing the jsPDF vulnerability should verify the following controls are in place:
- Software inventory identifies jsPDF and its transitive dependencies.
- Patched versions are deployed to production and propagated downstream.
- WAF and CSP rules restrict malicious payload delivery in browsers.
- Logging and telemetry capture PDF generation events for anomaly detection.
These steps help confirm the jsPDF vulnerability is closed and reduce the risk of regressions.
Implications for teams addressing CVE-2024-21484
Rapid patching lowers legal, operational, and reputational risk while preserving the benefits of client-side PDF generation. Upgrading promptly also streamlines compliance reporting and demonstrates mature vulnerability management.
For many teams, resolving the jsPDF vulnerability strengthens supply chain hygiene and reduces exposure to cascading issues.
However, legacy code paths and complex rendering pipelines can complicate sanitization and validation. Some organizations will need compatibility testing, template refactoring, or phased rollouts.
Apps that rely on rich HTML-to-PDF features may require tighter content controls to harden against the jsPDF vulnerability, potentially affecting user-generated content or document fidelity.
- Passpack – Shared credential management for dev and ops teams.
- IDrive – Encrypted backups to reduce impact of compromise.
- Auvik – Network visibility to spot anomalous traffic tied to exploits.
- Foxit PDF Editor – Enterprise-grade PDF tooling with robust security features.
Conclusion
The jsPDF vulnerability identified as CVE-2024-21484 demands immediate action. Apply the patch, verify deployment, and test hostile inputs to ensure full remediation.
Sustained resilience requires layered defenses. Enforce strict input validation, lock dependencies, and monitor PDF generation flows to contain future exposure.
By pairing rapid patching with disciplined controls, organizations can secure PDF workflows without sacrificing performance or usability.
