CVE-2026-15070
The Salon Booking System – Free Version plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 10.30.32. This is due to missing or incorrect nonce validation on the setCustomText function. This makes it possible for unauthenticated attackers to inject arbitrary PHP code into the web-accessible translate-constants.php file within the plugin directory, enabling remote code execution on the server via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. sanitize_text_field() is applied to the POST 'value' parameter but does not neutralize the characters — single quotes, parentheses, semicolons, $, and [] — required to break out of the PHP string literal into which the value is interpolated before being written to disk via file_put_contents().
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.
