Security readout for executives and security teams
Plain-English summary
This WordPress plugin flaw can let a logged-in user with Subscriber-level access or higher view personal details collected from maintenance-mode subscribers, such as names and email addresses. It is not described as unauthenticated or actively exploited, but it can expose contact data and create privacy, phishing, and compliance concerns.
Executive priority
Treat this as a moderate privacy-risk item. It is unlikely to cause service disruption, but it can expose contact data and increase phishing risk. Prioritize sites with public registration, large subscriber lists, or regulated personal information.
Technical view
CVE-2023-6922 is a CWE-200 sensitive information exposure in Under Construction / Maintenance Mode from Acurax through version 2.6. The issue is tied to the acx_csma_subscribe_ajax function. CVSS 3.1 is 4.3: network reachable, low complexity, low privileges required, no user interaction, confidentiality impact only.
Likely exposure
Exposure is limited to WordPress sites running the Acurax maintenance-mode plugin up to and including 2.6, where untrusted or broadly granted Subscriber-level accounts exist. Sites without this plugin, without collected subscriber data, or without low-privilege users have lower practical exposure.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The vulnerability requires an authenticated account, reducing internet-wide drive-by risk, but Subscriber-level access is commonly low-trust on some WordPress sites. The likely impact is disclosure of subscriber names and email addresses.
Researcher notes
Evidence supports authenticated sensitive information exposure via acx_csma_subscribe_ajax in versions through 2.6. The bundle does not provide exploit evidence, a confirmed patched version, or detailed vendor remediation language, so validation should focus on installed version, account trust model, and data sensitivity.
Mitigation direction
- Inventory WordPress sites for the Acurax maintenance-mode plugin.
- If version is 2.6 or older, check vendor guidance and update if available.
- Disable or remove the plugin where it is not operationally needed.
- Limit Subscriber-level accounts to trusted users until remediated.
- Review collected subscriber data for privacy and notification obligations.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record the installed plugin version and compare against 2.6 or older.
- Review whether public registration or low-trust Subscriber accounts are enabled.
- Check whether the plugin stores visitor names or email addresses.
- Review access logs for unusual authenticated subscription-data access patterns.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
