CVE-2025-32019Network attack vector

Stored XSS via unescaped repository descriptions

Published Jul 23, 2025 · Updated Jul 23, 2025

Stored XSS in GoHarbor Harbor before 2.11.3, 2.12.0-rc1 through 2.12.3, and 2.13.0-rc1 allows remote authenticated users to run script. UpdateRepository stores the submitted repository description directly, without HTML escaping, before the information tab renders its Markdown content. A user with repository-update access must save the payload and another user must view the information tab; the script then runs in the viewer's Harbor origin and can read accessible data.
