Security readout for executives and security teams
Plain-English summary
WP Mailster for WordPress has a high-severity blind SQL injection issue through version 1.8.16.0. A low-privileged authenticated attacker could potentially query database information indirectly. The provided sources do not identify active exploitation or a confirmed fixed version.
Executive priority
Treat this as a high-priority WordPress plugin exposure, especially on public sites with user accounts. Focus first on identifying affected installations, confirming vendor remediation, and reducing plugin or account exposure until a documented fix is available.
Technical view
CVE-2024-53807 is CWE-89 in brandtoss WP Mailster, package wp-mailster. The CVSS 3.1 score is 8.5 with AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L, indicating network access, low complexity, required low privilege, no user interaction, high confidentiality impact, and limited availability impact.
Likely exposure
Exposure is likely limited to WordPress sites with WP Mailster installed and running version 1.8.16.0 or earlier. The CVSS vector indicates an attacker needs low privileges, so sites allowing user accounts or contributor access should prioritize review.
Exploitation context
The bundle marks KEV as false and provides no cited evidence of active exploitation. The issue is blind SQL injection, so exploitation would generally rely on indirect database inference rather than visible query output. No exploit maturity details are provided.
Researcher notes
The source bundle gives severity, CVSS, affected product, and version boundary, but not vulnerable parameters, endpoint details, exploit availability, or a fixed version. Avoid assuming unauthenticated impact because the CVSS vector requires PR:L.
Mitigation direction
- Inventory WordPress sites for WP Mailster installations and versions.
- Check vendor or Patchstack guidance for a fixed release or official mitigation.
- Upgrade only to a vendor-confirmed fixed version when identified.
- Disable or remove WP Mailster where exposure cannot be accepted.
- Restrict creation and use of low-privileged WordPress accounts.
Validation and detection
- Confirm whether WP Mailster is installed on each WordPress site.
- Record the installed plugin version and compare it to 1.8.16.0.
- Review user roles for unnecessary low-privileged accounts.
- Monitor web and database logs for unusual plugin-related query behavior.
- Track vendor advisories for patch or mitigation confirmation.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
