CVE-2026-55555
Summary (concrete details from provided docs): Dompdf (PHP HTML-to-PDF converter) versions 3.15 and earlier are vulnerable to a File Existence Oracle via the CSS @font-face directive. An attacker can supply HTML that references local files with the file:// protocol to cause memory exhaustion, exp...
CVE-2026-55555 Dompdf: File existence oracle via font-face stylesheet declaration

CVE-2026-59942: Uncontrolled Resource Consumption
Dompdf is an HTML to PDF converter for PHP. Versions 3.15 and prior are 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...
CVE-2026-55555: Observable Discrepancy
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-2026-59941: Uncontrolled Resource Consumption
Dompdf is an HTML to PDF converter for PHP. Versions 3.15 and prior accept 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...
CVE-2026-55554: Improper Input Validation
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-2026-59943: Generation of Error Message Containing Sensitive Information
Dompdf is an HTML to PDF converter for PHP. In versions 3.15 and prior, 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...
CVE-2026-56722: Improper Input Validation
Dompdf is an HTML to PDF converter for PHP. In versions 3.15 and prior, aAn attacker who controls the HTML input can bypass this restriction by embedding a target file path inside an SVG image delivered through a data: URI, because dompdf processes the SVG twice and the second pass does not...
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...
Information Exposure
dompdf/dompdf is vulnerable to Information Exposure. The vulnerability is due to insufficient validation of data-URI embedded SVG elements, which allows an attacker to reference local files through the href or xlink:href attributes and exploit differences in file processing behavior to leak...
Denial Of Service (DoS)
dompdf/dompdf is vulnerable to Denial of Service DoS. The vulnerability is due to improper resource consumption controls during the PDF rendering phase after image dimension validation, which allows an unauthenticated attacker to submit a specially crafted HTML document containing a large...
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...
