DEBIAN-CVE-2026-55554

Dompdf is an HTML to PDF converter for PHP. In versions 3.15 and prior, the validateLocalUri method enforces chroot boundaries with a strpos prefix check after normalizing paths with realpath . Because normalization strips the trailing directory separator from $chrootPath , the check only...

CVE-2026-55555

Dompdf is an HTML to PDF converter for PHP. Versions 3.15 and prior are vulnerable to a File Existence Oracle attack through the manipulation of the CSS @font-face directive. By providing malicious HTML that references local files via the file:// protocol repeatedly, an attacker can trigger PHP...

CVE-2026-55554

Summary of CVE-2026-55554 (Dompdf) : Dompdf (PHP HTML-to-PDF converter) versions up to 3.15 are affected by a chroot validation bypass in validateLocalUri(), which uses a realpath-normalized prefix check with strpos. Because the trailing slash is removed during normalization, the chroot path is o...

CVE-2026-55555

Dompdf (versions ≤3.15) is vulnerable to a File Existence Oracle via the CSS @font-face directive, allowing an attacker to probe local files using file:// references and trigger memory exhaustion. The vulnerability hinges on observable differences: when a referenced local file exists, Dompdf proc...

Path Traversal

dompdf/dompdf is vulnerable to Path Traversal. The vulnerability is due to an improper prefix validation in the validateLocalUri method, where normalized paths are checked using strpos without enforcing directory boundaries, which allows an attacker who can control rendered HTML to escape the...

Path Traversal

dompdf/dompdf is vulnerable to Path Traversal. The vulnerability is due to improper validation of file paths when processing SVG images embedded through data: URIs, where the second SVG processing pass performed by php-svg-lib does not enforce the same security restrictions, allowing an...

File Existence Oracle

dompdf/dompdf is vulnerable to File Existence Oracle. The vulnerability is due to inconsistent handling of the CSS @font-face directive when processing local file:// resources, which allows an attacker to repeatedly reference local files and observe differences in memory exhaustion behavior to...

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: 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...
