jsPDF is a library to generate PDFs in JavaScript. Prior to 3.0.1, user control of the first argument of the addImage method results in CPU utilization and denial of service. If given the possibility to pass unsanitised image urls to the addImage method, a user can provide a harmful data-url that results in high CPU utilization and denial of service. Other affected methods are html and addSvgAsImage. The vulnerability was fixed in jsPDF 3.0.1.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
