CVE-2026-114727 · Severity: high · CVSS 8.3 · Published 2026-10-22

Roundcube Webmail, a popular email client accessed through a web browser, accepts SVG and EPS image files for contact photo uploads and resizes them using ImageMagick. These file formats can reference external resources and trigger ImageMagick delegates, potentially allowing attackers to read arbitrary files from the server or perform server-side request forgery attacks.

## Technical details

The vulnerability exists in the image resizing functionality, which accepts SVG and EPS files as valid image types for contact photo uploads. Both formats support references to external resources and can invoke ImageMagick delegates during processing, enabling potential file disclosure or SSRF. The fix removes SVG and EPS from the list of accepted image formats, preventing these dangerous file types from being processed by ImageMagick.
