Security readout for executives and security teams

Plain-English summary

This CVE describes a username-enumeration weakness in REDCap 14.3.13. An unauthenticated attacker may be able to tell whether a username exists by observing differences during login attempts. The direct impact is limited information disclosure, but it can support password guessing, phishing, or account-targeting activity.

Executive priority

Handle as a moderate-priority identity-risk issue. It does not indicate direct system takeover, but exposed REDCap login pages could help attackers target valid users. Prioritize externally reachable healthcare or research environments.

Technical view

The issue is classified as CWE-203, observable discrepancy. The CVSS 3.1 vector is network-accessible, low complexity, unauthenticated, no user interaction, unchanged scope, with low confidentiality impact only. The source bundle names REDCap 14.3.13, but normalized affected-product metadata is incomplete.

Likely exposure

Organizations running REDCap 14.3.13 with a reachable login interface are the most likely exposed. The provided CVE metadata does not identify additional affected versions or CPEs, so broader exposure cannot be confirmed from these sources alone.

Exploitation context

The CVE is not listed as CISA KEV in the provided bundle. A public GitHub reference exists, but the bundle does not establish active exploitation. Treat this as a credential-attack enabler rather than a standalone compromise path.

Researcher notes

Evidence is narrow: the CVE description, CVSS vector, CWE-203 mapping, and one GitHub reference. Do not assume additional REDCap versions, active exploitation, or a vendor patch unless confirmed by official guidance.

Mitigation direction

  • Check official REDCap/vendor guidance for a fixed version or workaround.
  • Prioritize upgrading REDCap 14.3.13 if vendor guidance confirms a fix.
  • Restrict external access to REDCap login pages where business allows.
  • Enable MFA to reduce follow-on account compromise risk.
  • Monitor and rate-limit repeated failed login attempts.

Validation and detection

  • Inventory REDCap deployments and confirm whether version 14.3.13 is present.
  • Review whether REDCap login pages are internet-accessible or broadly reachable.
  • Check authentication logs for repeated username-focused failed login patterns.
  • In authorized testing, verify login failures do not reveal user validity.
  • Track vendor advisories because affected-version metadata is incomplete.
