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.
