CVE-2023-47185Network attack vector

Unauthenticated stored XSS via uploaded image filenames

Published Nov 6, 2023 · Updated Apr 29, 2026

Stored XSS in gVectors Team wpDiscuz 7.6.11 and earlier allows remote attackers to inject scripts through uploaded image filenames. Comment-upload filename handling stores attacker-controlled names without sufficient sanitization and later renders them without output escaping. No account is required to submit the filename, but a user must visit the affected page for the stored script to execute in that user's browser.
