WPS Bookings for WooCommerce: Unauthenticated price manipulation in booking checkout
Summary
The WordPress plugin WPS Bookings for WooCommerce does not validate a user-supplied price value before using it to set the product price. An unauthenticated attacker can purchase bookable services at a price of their choosing, including zero. The flaw affects a network-reachable WooCommerce shop running the plugin before version 3.13.1, and the impact is limited to integrity (financial loss).
Affected
- WPS Bookings for WooCommerce (slug mwb-bookings-for-woocommerce) before 3.13.1
- Vendor attribution to WP Swings is probable but not yet confirmed against the wordpress.org plugin page.
Fixed in
- Version 3.13.1 (released 05 Nov 2026)
Workaround
- Unknown. No vendor-published workaround found.
- Interim measure: review recent WooCommerce orders for bookable services with zero or unusually low totals.
Exploitation
- In the wild: Not known.
- CISA KEV: Not listed.
- Public exploit code: none reported by aggregators; unverified.
- CISA SSVC: Automatable yes, technical impact partial.
Our recommendation
- Update WPS Bookings for WooCommerce to version 3.13.1 or later.
- Check whether the plugin is installed on internet-facing WooCommerce shops and verify the installed version.
- Review recent bookings and orders for zero or unusually low totals.
- Recheck CISA KEV and vendor sources in the coming days, as the NVD analysis is still pending.
