CVE-2026-110033
MEDIUM 6.8 PoC AVAILABLEThe Salon Booking System WordPress plugin before 10.31.11 does not validate a user-supplied image URL before fetching it server-side and writing the response to a publicly accessible location under an attacker-chosen filename, allowing users with the Salon Staff role or higher to force the server to read internal-only resources and disclose them, and to store a malicious SVG that runs arbitrary scripts in the site's origin for anyone who opens it.
Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
