Elementor Pro vulnerability CVE-2023-3124 was reported as actively exploited in April 2023. It affected versions through 3.11.6 and could let an authenticated user with subscriber-level capabilities change site options. Version 3.11.7 was the first release identified as fixing this flaw, but it is an outdated release threshold—not a safe target today. Update Elementor Pro to the latest release available through a trusted channel, and investigate any signs of unauthorized site changes.
What was the Elementor Pro vulnerability?
CVE-2023-3124 was an authorization flaw in Elementor Pro’s update_page_option function. The function lacked a capability check, allowing an authenticated attacker with subscriber-level capabilities or higher to update arbitrary site options. The GitHub Advisory Database assigns the vulnerability a CVSS 3.1 score of 8.8 (High). GitHub Advisory Database: CVE-2023-3124.
Changing site options could enable privilege escalation and other harmful changes. Singapore’s Cyber Security Agency said an attacker could redirect visitors to malicious domains or upload backdoors. It also warned that, when WooCommerce was installed, an authenticated user such as a customer or site member could change settings and potentially take over the site. Singapore Cyber Security Agency alert, 1 April 2023.

If your site still runs 3.11.6 or earlier, it is within the affected range. If it runs 3.11.7 or later, that addresses this documented flaw, but 3.11.7 is not a current general security recommendation: later releases may contain fixes for other vulnerabilities. Check your installed version in WordPress and update to the latest release applicable to your site.
Was CVE-2023-3124 actively exploited?
Yes. Singapore’s Cyber Security Agency reported active exploitation on 1 April 2023, and the University of Michigan issued a similar warning on 3 April 2023. These are historical reports; they establish exploitation at that time, not current attack activity for this specific CVE.

Could a subscriber or WooCommerce customer hack a site?
The flaw required authentication, so the reports do not describe an unauthenticated visitor exploiting it. The vulnerable function could be reached by an authenticated attacker with subscriber-level capabilities or higher. The Cyber Security Agency specifically warned that, on sites also running WooCommerce, an authenticated customer or member could change settings and potentially take over the site. The University of Michigan said a site user could create an administrator account in that WooCommerce context.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Having WooCommerce installed does not by itself show that a site was compromised. The risk described was conditional on the vulnerable Elementor Pro version and an attacker having an account with the required access.

How to protect an Elementor Pro site
- Check the installed version. In WordPress, open the Plugins page and find Elementor Pro. Compare its version with the affected threshold: 3.11.6 and earlier.
- Update through a trusted channel. Install the latest release applicable to your site using the normal trusted update channel. Do not stop at 3.11.7 simply because it was the first version that patched CVE-2023-3124.
- Disable or remove the plugin if it is not needed. The University of Michigan’s alert recommended updating or disabling/removing Elementor Pro when it was unnecessary.
- Review signs of unauthorized changes. Pay attention to unfamiliar administrator accounts, unexpected redirects, or suspected backdoors. An update addresses the documented software flaw; it does not establish whether an attacker already changed your site.
- Escalate suspected compromise. If you find unauthorized accounts, redirects, or backdoors, contact your hosting provider or a qualified incident responder. The cited alerts do not provide a complete forensic checklist, so avoid treating a plugin update alone as incident cleanup.
The Cyber Security Agency’s 1 April 2023 alert advised users and administrators of affected versions to “update to the latest version immediately.” Its version threshold is historical; follow the current update channel rather than installing an old release based on that alert.
