Security For WooCommerce: Disclosure of administrator email addresses
Summary
The Security For WooCommerce WordPress plugin up to and including version 1.0.16 does not restrict access to one of its REST API routes. An unauthenticated attacker can retrieve the email addresses of all administrators of the affected WordPress site. The disclosed addresses can be used for targeted phishing, social engineering or credential-stuffing attacks, but the flaw does not directly enable further compromise.
Affected
- Security For WooCommerce WordPress plugin, all versions up to and including 1.0.16
- Affected component: one REST API route without authorization check
Fixed in
Unknown. VulDB refers to version 1.0.17 or later, but this is not confirmed by the vendor or the WPScan advisory.
Workaround
- Block or restrict the affected REST route at the web server, reverse proxy or WAF (route name not confirmed in the sources)
- Restrict access to REST API endpoints that do not need to be public, instead of disabling the whole REST API
- Deactivate and delete the plugin if it is not required
Exploitation
- No confirmed exploitation in the wild; not listed in the CISA KEV catalogue
- No public proof-of-concept exploit confirmed
- CISA SSVC: automatable yes, technical impact partial
Our recommendation
- Identify WooCommerce sites running the plugin in version 1.0.16 or earlier
- Check the WPScan advisory and the plugin changelog for the confirmed fixed version before updating
- If no fix is confirmed, restrict the REST route at the proxy or WAF, or remove the plugin
- Enforce two-factor authentication for administrator accounts and do not use admin email addresses as usernames
- Review the related CVE-2026-123702 and CVE-2026-123705 at the same time
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
