Deeper analysis
The Relevanssi – A Better Search plugin for WordPress is affected by CVE-2024-1380, an instance of CWE-862 missing authorization. The flaw stems from the absence of a capability check in the relevanssi_export_log_check() function, impacting all versions through 4.22.0 in the free edition and 2.25.0 in the premium edition. This permits unauthenticated access to query log data via a network-reachable endpoint, corresponding to a CVSS 3.1 score of 5.3.
Unauthenticated remote attackers can invoke the affected function directly to export the plugin’s stored search query logs without any authentication or authorization. Successful exploitation yields read access to potentially sensitive usage data but does not permit modification or service disruption.
Wordfence and the WordPress plugin repository note that the vendor has stated the issue is “theoretically patched as is,” while indicating a possible future addition of a capability check; the referenced changesets do not introduce an explicit authorization control. The EPSS score has remained elevated, with a current value of 0.8453 and a recorded peak of 0.8750.

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.
