Description
The JS Help Desk – AI-Powered Support & Ticketing System plugin for WordPress is vulnerable to Sensitive Information Exposure via the company supervisor feature in versions 5.0.0 up to, and including, 5.0.5, due to JSSTcompanies::supervisorReads() and sharedScopeClause() granting read access to every ticket of a company's people based only on the account's e-mail address, which the plugin's own sign-up form accepts without proving ownership of the mailbox. This makes it possible for unauthenticated attackers, on sites where registration is open, to register with a company supervisor's address that has no account yet and read the support tickets of that company's other customers.
