Security readout for executives and security teams
Plain-English summary
This vulnerability lets someone bypass submission limits in the WordPress RegistrationMagic plugin. The business risk is misuse of public registration or form workflows, not data theft or server takeover based on the supplied sources. Sites using version 5.2.5.0 or earlier should review exposure and vendor guidance.
Executive priority
Prioritize as a moderate operational integrity issue. It is most urgent for public-facing registration, lead, membership, or compliance workflows where submission limits are relied on for abuse prevention.
Technical view
CVE-2023-51544 is a CWE-799 improper control of interaction frequency issue in Metagauss RegistrationMagic through 5.2.5.0. CVSS 3.1 is 5.3: network exploitable, low complexity, no privileges, no user interaction, unchanged scope, no confidentiality or availability impact, and low integrity impact.
Likely exposure
Exposure is likely limited to WordPress sites running RegistrationMagic, package custom-registration-form-builder-with-submission-manager, through version 5.2.5.0, especially where public forms rely on submission limits to prevent repeat or abusive submissions.
Exploitation context
The CVSS vector indicates unauthenticated remote reachability, but the source bundle does not show KEV listing, active exploitation, exploit maturity, or weaponized details. Treat exploitation status as unconfirmed.
Researcher notes
Evidence supports frequency-control bypass and limited integrity impact only. The supplied sources do not name a fixed version, workaround, exploit, or detailed vulnerable code path, so remediation should be tied to vendor-confirmed guidance.
Mitigation direction
- Inventory WordPress sites using RegistrationMagic.
- Check whether installed versions are 5.2.5.0 or earlier.
- Review Metagauss and Patchstack guidance for fixed versions or vendor mitigations.
- Update only to vendor-supported fixed releases when identified.
- Restrict or disable exposed affected forms if updates are unavailable.
- Monitor form activity for repeated submissions beyond intended limits.
Validation and detection
- Confirm plugin package name and installed version in WordPress administration.
- Identify public RegistrationMagic forms using submission limits.
- Review submission logs for repeated entries exceeding configured limits.
- Check whether compensating controls enforce rate or submission limits.
- Document any affected workflows and business owners.
