CVE-2025-52462Network attack vector

Browser script execution via unsafe HTML preview

Published Jul 2, 2025 · Updated Jul 2, 2025

Cross-site scripting in QUALITIA Active! mail 6 builds 6.30.01004145 through 6.60.06008562 allows remote attackers to run browser scripts. When a logged-in user edits an HTML email containing JavaScript in the mail-composition screen and opens its preview, the preview executes the embedded code instead of neutralizing it. Exploitation requires an old or unsupported browser and user interaction, and the script can perform actions in the logged-in user's web session.
