Reflected XSS via unsanitized page parameter
Published Aug 19, 2026 · Updated Aug 19, 2026
Reflected XSS in ProSolution WP Client before 2.0.11 allows remote attackers to execute script in an administrator session via a crafted request. On an administrative page, the plugin reflects the page parameter into an HTML attribute without sanitization or output escaping, so attacker-controlled markup reaches the browser as executable script. Exploitation requires convincing an administrator to submit the crafted request; the available records describe script execution in that session but no broader server-side impact.
