CVE-2026-71292
Subrion CMS's admin grid sorting helper, _gridGetSorting() in includes/classes/ia.base.controller.admin.php, whitelists the `dir` (ASC/DESC) request parameter via in_array(), but falls back to the raw, attacker-supplied `sort` GET parameter whenever the requested key is not present in the per-controller $_gridSorting whitelist array: `$column = isset($this->_gridSorting[$params['sort']]) ? ... : $params['sort'];`, which is then placed into `sprintf(' ORDER BY %s`%s` %s', $tableAlias, $column, $direction)` with only backtick-quoting and no escaping. Because a backtick in the payload breaks out of the identifier context, an authenticated admin session can inject arbitrary SQL (error-based via EXTRACTVALUE, or time-based via SLEEP()) to extract database contents including administrator password hashes. Most of Subrion's ~29 admin grid controllers either define no $_gridSorting whitelist at all (e.g. pages.php, transactions.php, languages.php) or an incomplete one covering only some of their sortable columns (e.g. members.php whitelists only 1 of 7 sortable fields), making the vast majority of admin grid endpoints exploitable.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
