CVE-2026-110033 · Severity: info · Published 2026-10-18

The Salon Booking System WordPress plugin allows staff members to upload images by providing a URL, but fails to validate the URL before fetching it. This allows attackers to force the server to read internal files and expose their contents, or upload malicious SVG files that execute scripts in visitors' browsers, compromising site security.

## Technical details

The plugin's image URL handler does not validate user-supplied URLs before performing server-side fetches, enabling both Server-Side Request Forgery (SSRF) and stored Cross-Site Scripting (XSS). Users with Salon Staff role or higher can request internal resources and have responses written to publicly accessible paths under attacker-controlled filenames, or upload SVG files containing arbitrary scripts that execute in the origin context. The vulnerability requires authenticated access at the Salon Staff privilege level or above.
