Technical details
The share mini page fails to sanitize or escape the article link parameter when the "Share article links" option is enabled, allowing stored XSS injection. With the "Image Page with Redirect" link type, unsanitized input is also followed as a redirect target. An attacker can craft a malicious share link that executes JavaScript in the victim's browser session or redirects them to an attacker-controlled site; no server-side data is compromised.
