GHSA-J8QW-6JW8-R297 Dompdf: Embedded SVG images can leak existence of files and directories within the filesystem
Summary If a malicious actor can supply unrestricted content for rendering by Dompdf they can utilize the SVG rendering functionality to leak filesystem information when rendering PDF files using image references within a data-URI encoded SVG document. Details Using an element inside a data-URI...
Information Exposure
Overview Affected versions of this package are vulnerable to Information Exposure via the processing of embedded SVG images containing elements with xlink:href attributes referencing local files or directories. An attacker can determine the existence of files or directories on the server by...

Allocation of Resources Without Limits or Throttling
Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the render process. An attacker can exhaust system resources and cause the PHP process to crash by submitting a specially crafted HTML document containing a high-entropy,...
Dompdf: Denial of Service (DoS) via Resource Exhaustion using Oversized Image Bitmaps
Summary Dompdf v3.1.5 is vulnerable to a Denial of Service DoS attack via resource exhaustion. An attacker can crash the PHP process by providing a specially crafted HTML document containing a single image with massive dimensions e.g., 30,000x30,000 pixels. While Dompdf implements internal checks...

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,...
Denial of Service (DoS)
Overview Affected versions of this package are vulnerable to Denial of Service DoS via the imagecreatefrombmp process. An attacker can cause excessive memory and CPU consumption by submitting a specially crafted BMP image with large declared dimensions embedded as a data URI in HTML. This can lea...

GHSA-WVH6-F5JH-8GW4 Dompdf: Chroot Validation Bypass
Summary The chroot check for local files uses a prefix string check to enforce chroot boundaries. The simple string comparison it performs allows paths like /var/www/rootsecret/file.html when chroot is /var/www/root. This allows attacker-controlled document paths/resources to bypass intended loca...
