Uncontrolled Resource Consumption

dompdf/dompdf is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to the library trusting attacker-controlled BMP header dimensions without validating the image size before conversion, which allows an attacker to embed a crafted BMP image e.g., via a data:image/bmp;base64...

Dompdf: Uncontrolled resource consumption based on declared BMP dimensions

Summary dompdf accepts a BMP image and generates a PDF-compatible PNG based only on its declared header dimensions and never bounds width × height before the image is converted through GD. A 58-byte BMP whose header declares e.g. 6000×6000 is accepted and later drives imagecreatetruecolor$width,...

CVE-2026-24133 jsPDF Affected by Denial of Service (DoS) via Unvalidated BMP Dimensions in BMPDecoder

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...

CVE-2026-24133

The CVE-2026-24133 issue affects jsPDF (prior to 4.1.0) where user control of the first addImage argument allows denial of service when processing unvalidated BMP data or URLs, including via the html method. Harmful BMP headers with large width/height trigger excessive memory allocations, leading...
