Security readout for executives and security teams
Plain-English summary
This is a medium-severity access-control flaw in a WordPress WooCommerce plugin used for live sales notifications. An unauthenticated remote attacker may access information they should not see. The published impact is limited to confidentiality, with no stated integrity or availability impact.
Executive priority
Treat this as a routine but timely WordPress plugin risk. Prioritize stores using the plugin on public sites, especially where customer or order-adjacent data could be exposed. No public source here confirms active exploitation.
Technical view
CVE-2026-27066 is a CWE-862 Missing Authorization issue in PI Web Solution Live sales notification for WooCommerce. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, score 5.3. Sources state versions through 2.3.60 are affected, though one reference URL mentions 2.3.44, so version evidence should be verified.
Likely exposure
Exposure is likely limited to WordPress sites using WooCommerce with the live-sales-notifications-for-woocommerce plugin installed and active. Internet-facing stores are the main concern because the CVSS vector indicates network access and no required authentication.
Exploitation context
The source bundle does not indicate active exploitation, and KEV is false. The vulnerability is remotely reachable with low attack complexity and no user interaction, but the documented security impact is only low confidentiality exposure.
Researcher notes
Evidence is sparse. The CVE states affected through 2.3.60, while the Patchstack URL text references 2.3.44. No patch version, exploit details, or concrete exposed endpoint is provided in the supplied sources. Avoid assuming broader WooCommerce or WordPress core impact.
Mitigation direction
- Inventory WordPress sites for the live-sales-notifications-for-woocommerce plugin.
- Check the installed plugin version against vendor, WordPress, or Patchstack guidance.
- Update if a fixed version is available from trusted plugin sources.
- Disable or remove the plugin where it is not business-critical.
- Monitor vendor and Patchstack advisories for confirmed remediation details.
Validation and detection
- Confirm whether the plugin is installed and active on WooCommerce sites.
- Record exact plugin versions, especially any version at or below 2.3.60.
- Review web logs for unusual unauthenticated access to plugin-related endpoints.
- Verify compensating controls do not replace the need for a vendor fix.
- Track CVE and Patchstack entries for updated affected-version details.
