CVE-2026-19055Network attack vector

Reflected XSS via unescaped HTML attributes

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 visitors' browsers via crafted public-page parameters. Public portal templates emit add_query_arg()-derived URLs and attribute values such as jobid, source, and searchlist into HTML attributes without esc_url() or attribute escaping. Exploitation requires luring a victim to a crafted link or request to a public page; execution occurs in that visitor's session, including an administrator's browser.
