Summary
paicoding 1.0.0 through 1.0.3 contains a stored cross-site scripting vulnerability because SeoInjectService embeds user profile text without escaping in an inline JSON-LD script element. Authenticated attackers can add a closing script tag followed by HTML to their profile, executing scripts for visitors of their profile page and stealing the non-HttpOnly f-session cookie.
