CVE-2023-34423Network attack vector

Stored script execution in administrator browsers

Published Apr 3, 2024 · Updated Nov 6, 2024

Stored cross-site scripting in AYS Pro Plugins Survey Maker before 3.6.4 allows remote attackers to execute scripts in an administrator's browser. The CNA record and JPCERT/CC advisory do not disclose the affected input, code path, or missing neutralization operation that stores the script. Exploitation requires an administrator to sign in to the WordPress site, and the script executes only in that browser context.
