Smoove Abandoned Cart Trigger for WooCommerce: Unauthenticated stored XSS in admin dashboard
Summary
The Smoove Abandoned Cart Trigger for WooCommerce WordPress plugin does not sanitise or escape abandoned-cart data submitted by visitors before displaying it in the admin dashboard. An unauthenticated attacker can store malicious script code this way, which runs in the browser of an administrator who views the abandoned-cart data. A successful attack could lead to session hijacking or full takeover of the WordPress site, provided an administrator opens the affected page.
Affected
- Smoove Abandoned Cart Trigger for WooCommerce 4.0.0 up to and including 4.3.5 (per CNA data and WPScan; not verified against the vendor changelog)
- Versions before 4.0.0: Unknown
Fixed in
- Version 4.3.6 (per aggregator sources; vendor changelog not confirmed)
Workaround
- If an update is not possible, deactivate the plugin if the abandoned-cart feature is not required.
- A third-party source suggests a WAF rule against XSS payloads in POST requests to abandoned-cart endpoints; this is generic advice and not confirmed by the vendor.
Exploitation
- No known exploitation in the wild; not listed in CISA KEV.
- No public proof-of-concept exploit found in Metasploit or Exploit-DB.
- Conflicting reports on whether a public nuclei detection template exists; unresolved.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Check whether the plugin is installed on each WooCommerce WordPress site and which version is active.
- Update to version 4.3.6 or later as soon as possible.
- Until patched, restrict admin access and avoid viewing abandoned-cart data if possible.
- After patching, review stored abandoned-cart records for script content.
- Monitor for public exploit publication and recheck the NVD score in the coming days.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
