Security For WooCommerce WordPress plugin: Missing authorization in 2FA reset
Summary
The Security For WooCommerce WordPress plugin up to and including version 1.0.16 does not check whether the requester is authorised before resetting two-factor authentication enrolment. An unauthenticated attacker on the internet can remove the second factor from any account, or from all accounts at once. The attack needs no login, but resetting 2FA alone does not give access, so the attacker would still need the password or another flaw.
Affected
- Security For WooCommerce WordPress plugin, all versions through 1.0.16
- Reported as the plugin "ultimate-security-for-woocommerce" (not confirmed by a primary source)
Fixed in
Unknown.
Workaround
- Deactivate the plugin if it is not essential.
- Restrict access to the plugin's endpoints at the web server or WAF (no vendor mitigation published).
- Review admin accounts for unexpected 2FA resets.
Exploitation
- Not listed in CISA KEV.
- OffSeq reports not known to be exploited.
- Public proof-of-concept code: unknown.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Check whether the plugin is installed, including on staging sites.
- Deactivate it if it is not needed.
- Watch the WPScan advisory and the vendor for a patch.
- Review admin accounts and logins for signs of compromise.
- Assume the related CVE-2026-123695, CVE-2026-123697 and CVE-2026-123701 in the same plugin also apply.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
