CVE-2026-42150

EUVD-2026-28501
wlc is a Weblate command-line client using Weblate's REST API. Prior to version 2.0.0, the HTML output format in wlc embeds API response data into HTML without escaping, allowing cross-site scripting when the output is rendered in a browser. This issue has been patched in version 2.0.0.
