AI Analysis
Technical Summary
CVE-2026-11875 is an authorization bypass vulnerability in the WP Support Plus Responsive Ticket System WordPress plugin through version 9.1.2. The vulnerability arises because the plugin does not sign or verify its guest-session cookie, which is user-controlled. This allows unauthenticated attackers to forge the cookie and impersonate ticket owners identified by their email addresses, thereby gaining unauthorized access to sensitive ticket operations such as reading, replying to, and closing support tickets.
Potential Impact
An attacker can impersonate any ticket owner without authentication, leading to unauthorized access and manipulation of support tickets. This compromises the confidentiality and integrity of user support data and could disrupt support processes.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor the vendor's communications for updates and consider restricting access to the plugin or disabling it if feasible to prevent exploitation.
