Technical description

LinkedIn Mobile Application for Android version 4.1.1087.2 fails to update link preview metadata (image, title, description) when a user replaces the original URL in a post or comment before publishing.

This UI misrepresentation enables attackers to deceive users by displaying trusted previews for harmful links, facilitating phishing attacks and user confusion.
