    Reverse Tabnabbing in showdown

    GHSA-h6mq-3cj6-h738

    Affected
    • npm showdown < 1.9.1
    Fixed in
    1.9.1· Vendor fix available
    Issue
    Versions of showdown prior to 1.9.1 are vulnerable to Reverse Tabnabbing. The package uses target='blank' in anchor tags, allowing attackers to access window.opener for the original page when opening links. This is commonly used for phishing attacks. Recommendation Upgrade to version 1.9.1 or later.

    Recommended action: Upgrade to 1.9.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
