Published: 18 April 2022
Summary
CVE-2022-1054 is a medium-severity Missing Authorization (CWE-862) vulnerability in Wpchill Rsvp And Event Management. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 6.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The RSVP and Event Management Plugin for WordPress before version 2.7.8 contains a missing authorization vulnerability (CWE-862) in its entry export functionality. The export function is registered on the init action without any permission checks, exposing an unauthenticated endpoint that returns event registration data.
Unauthenticated remote attackers can invoke the export routine directly over the network to retrieve personally identifiable information such as first names, last names, and email addresses of registered users. The flaw carries a CVSS 3.1 score of 5.3, reflecting limited impact confined to confidentiality.
WPScan advisories for this issue recommend updating the plugin to version 2.7.8 or later to close the unauthorized export path. The associated EPSS score rose from a low baseline to a peak of 0.1550, indicating measurable post-disclosure exploitation interest.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
