# CVE-2026-120501: An Otter Wiki 2.20.1 before 2.26.2 Repository File Disclosure via DataTable src

Status: published. Published: 2026-11-02. Updated: 2026-11-02.

An Otter Wiki 2.20.1 before 2.26.2 contains a file disclosure vulnerability in the DataTable embedding that allows attackers who can edit pages, including anonymous users under the default configuration, to read repository-internal files. Attackers can set an absolute src such as /.git/config to render the file as a table, exposing any stored remote credentials.
