SCA: security update for concrete5/concrete5 (GHSA-h72c-xx3w-w8h7)

high Tenable Self-Hosted Container Security Plugin ID 443891

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 gave this vulnerability a CVSS v.4.0 score of 7.3 with
vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N Thanks Yonatan Drori (Tenzai) for
reporting. (CVE-2026-8197)

Solution

Update the concrete5/concrete5 library and its related packages to version 9.5.1 or later.
