Session-cookie theft via stored Add Link script
Published Aug 5, 2021 · Updated Aug 4, 2024
Stored XSS in OneNav beta 0.9.12 allows remote authenticated users to execute script in another user's browser through Add Link. The Add Link workflow stores a submitted script payload without neutralizing it and later renders the value as executable page content. A compromised account must create the link and another user must view it, after which the script can read that user's session cookie.
