AI-suggested
Users should apply any future updates from the vendor once available. Until then, restricting profile input to disallow script tags or sanitizing user input before embedding it in JSON-LD scripts can reduce risk. Monitoring for suspicious profile content and limiting privileges of authenticated users may also help mitigate exploitation.
Description
paicoding versions 1.0.0 through 1.0.3 have a stored cross-site scripting (XSS) vulnerability. This occurs because the SeoInjectService embeds user profile text directly into an inline JSON-LD script element without proper escaping. Authenticated attackers can exploit this by injecting a closing script tag and arbitrary HTML into their profile, which executes scripts in the context of visitors viewing the profile page. This can lead to theft of non-HttpOnly f-session cookies.
