Attackers can craft GET requests to /wp-content/plugins/socialfit/popup.php with service=googleplus and malicious msg values to execute script and steal session cookies. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.","summary":"The SocialFit WordPress plugin through 1.2.2 echoes the msg parameter of popup.php without sanitizing it, so a crafted link runs attacker script in the victim's browser.
