CVE-2019-20460

Unauthorized printing via unvalidated cross-site requests

Published Nov 7, 2024 · Updated Nov 4, 2025

Cross-site request forgery in Epson Expression Home XP-255 20.08.FM10I8 allows remote attackers to submit printer actions via crafted POST requests. The web administration panel accepts state-changing POST requests without anti-CSRF tokens or another check that the request came from a legitimate source. An attacker must reach the printer over the adjacent network and induce user interaction; successful abuse can send attacker-chosen text to the RAW printing interface and produce an unauthorized printout.
