DescriptionGitHub Advisory
jsPDF is a library to generate PDFs in JavaScript. Prior to 4.1.0, 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 BMP file that results in out of memory errors and denial of service. Harmful BMP files have large width and/or height entries in their headers, which lead to excessive memory allocation. The html method is also affected. The vulnerability has been fixed in jsPDF@4.1.0.
AnalysisAI
Denial of service in jsPDF prior to version 4.1.0 occurs when malicious BMP files with oversized dimension headers are processed by the addImage or html methods, causing excessive memory allocation and application crashes. Public exploit code exists for this vulnerability. Organizations using jsPDF should upgrade to version 4.1.0 or later to remediate the issue.
