Stored XSS via unsanitized CSV upload filename

Published Mar 15, 2026 · Updated May 24, 2026

Stored cross-site scripting in Next Click Ventures RealtyScript 4.0.2 allows remote attackers to run script in users' browsers.

Execution requires a user to process or view the uploaded entry, after which the script runs in the affected site's browser context and can act with that user's session.
