Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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. As a result, the stale preview remains visible while the clickable link points to a different URL, which can be malicious. This UI misrepresentation enables attackers to deceive users by displaying trusted previews for harmful links, facilitating phishing attacks and user confusion.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The LinkedIn Android app fails to refresh link preview metadata (image, title, description) when a user modifies the URL in a post or comment before publishing. This creates a mismatch where users see a trusted preview (e.g., for linkedin.com) while the actual clickable link points to a different, potentially malicious URL, enabling phishing attacks.

MitigationImplement proper validation to refresh/update link preview metadata whenever the URL is modified, or display a warning when the preview doesn't match the current URL being posted.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if LinkedIn Android app is installed
    Use Android Package Manager (pm) command: `pm list packages | grep linkedin` or check in Settings > Apps for 'LinkedIn'
    Affected if LinkedIn Android app is installed on the device
  2. Retrieve the installed LinkedIn app version
    Run: `dumpsys package com.linkedin.android | grep versionName` or check via Settings > Apps > LinkedIn > App info > Version
    Affected if The displayed version is 4.1.1087.2 exactly
  3. Compare version against affected range
    Verify if installed version equals 4.1.1087.2 - note this is an exact version match per the CVE
    Affected if Installed version is exactly 4.1.1087.2, indicating the vulnerable version is present
  4. Test link preview behavior (if affected version)
    In the LinkedIn app, create a post or comment with a URL (e.g., linkedin.com), observe the preview, then modify the URL to a different domain before publishing, and verify whether the preview metadata updates to reflect the new URL
    Affected if The preview continues showing metadata from the original URL while the actual link points to the modified URL - confirming the vulnerability is exploitable

A user is affected if they have LinkedIn Android app version 4.1.1087.2 installed and use the link preview feature in posts or comments, where URL modification does not trigger preview metadata refresh.
