UBUNTU-CVE-2021-38295 (CVE-2021-38295)

Vulnerability from osv_ubuntu – Published: 2021-10-14 20:15 – Updated: 2025-10-24 04:50 – Source website

Details

In Apache CouchDB, a malicious user with permission to create documents in a database is able to attach a HTML attachment to a document. If a CouchDB admin opens that attachment in a browser, e.g. via the CouchDB admin interface Fauxton, any JavaScript code embedded in that HTML attachment will be executed within the security context of that admin. A similar route is available with the already deprecated _show and _list functionality. This privilege escalation vulnerability allows an attacker to add or remove data in any database or make configuration changes. This issue affected Apache CouchDB prior to 3.1.2
