| Package | Affected versions | Patched versions |
|---|---|---|
| concrete5/concrete5 | < 9.5.1 | 9.5.1 |
| concrete cms | ≤ 9.5.0 |
Concrete CMS 9.5.0 and below is vulnerable to Stored XSS via OAuth integration name. The OAuth authorize template renders the integration name (admin-controlled) through Concrete's t() translation helper as a sprintf-style format. The <strong>...</strong> wrap is built by PHP string interpolation before t() runs, so the integration name lands in the translated output as raw HTML. A rogue admin could potentially snoop on login submissions.The Concrete CMS security team thanks Yonatan Drori (Tenzai) for reporting this issue.
