Technical details
A stored cross-site scripting (XSS) vulnerability exists in the PSM Plugins SupportCandy plugin for WordPress due to improper neutralization of input during web page generation. The flaw allows an authenticated attacker with low-level privileges to inject malicious scripts into certain fields that are later rendered for other users. Because the vulnerability is 'stored,' the payload remains on the server and executes in the context of any user (including administrators) who views the affected page. This can lead to session hijacking, unauthorized configuration changes, or further privilege escalation. The issue is addressed in version 3.4.9.
