Salon Booking System WordPress plugin: Privilege escalation without authentication
Summary
The Salon Booking System WordPress plugin up to and including version 10.31.7 contains a privilege escalation flaw that can be triggered without logging in. Under the CVSS vector, an attacker can gain full control over the affected WordPress site, but exploitation requires a privileged user to perform an action, such as clicking a malicious link or submitting a crafted form. The vendor's fixed version is not confirmed by the NVD; the Patchstack record recommends version 10.31.9 or later.
Affected
- Salon Booking System WordPress plugin, all versions up to and including 10.31.7
Fixed in
- Patchstack lists 10.31.9 as the patched version. The fix is not confirmed by the vendor changelog for this CVE.

Workaround
- Unknown. No vendor workaround was found. Patchstack reports a mitigation rule that blocks attacks until the plugin is updated.
Exploitation

- CISA SSVC: exploitation none, automatable no, technical impact total.

Our recommendation
- Inventory all WordPress sites running the plugin and record their versions.
- Update the plugin to the latest release (currently 10.31.12) rather than only to 10.31.9.
- Audit administrator and staff accounts and recent role changes; reset credentials if anything looks unfamiliar.
- Monitor the NVD and Patchstack pages for a confirmed fixed version.
