Details
As written in the advisory (Markdown source, shown as plain text).
# Summary
It was confirmed in a test environment that an attacker can store an HTML/JavaScript payload in a repository’s **Milestone name**, and when another user selects that Milestone on the **New Issue** page (`/issues/new`), a **DOM-Based XSS** is triggered.
# Impact
* Theft of information accessible in the victim’s session.
* Extraction of CSRF tokens and submission of state-changing requests with the victim’s privileges.
* Repository operations performed with the victim’s privileges (Issue operations, settings changes, etc.).
(The impact scope depends on the victim’s permission level.)
# Remediation
A fix is available at https://github.com/gogs/gogs/releases/tag/v0.14.2
