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
A vulnerability within the Avira Password Manager Browser Extensions provided a potential loophole where, if a user visited a page crafted by an attacker, the discovered vulnerability could trigger the Password Manager Extension to fill in the password field automatically. An attacker could then access this information via JavaScript. The issue was fixed with the browser extensions version 2.18.5 for Chrome, MS Edge, Opera, Firefox, and Safari.

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.
