Deeper analysis
The WordPress Gallery Plugin – NextGEN Gallery, in versions up to and including 3.59, is affected by an information disclosure vulnerability (CVE-2024-3097) stemming from a missing capability check on the get_item function in the plugin's REST API handler. This flaw, assigned CWE-862 and rated 5.3 on CVSS 3.1, allows unauthenticated network access to extract EXIF and other metadata from any image uploaded through the plugin.
Unauthenticated attackers can invoke the affected endpoint directly to retrieve sensitive image metadata without authentication or user interaction, exposing details that would otherwise require elevated privileges.
Advisories from Wordfence and the plugin's Trac repository reference a corrective changeset to src/REST/Admin/Block.php that addresses the missing authorization check, with the fix available in subsequent releases beyond 3.59.
The EPSS score for this CVE rose from lower values to a peak of 0.3936 before receding to the current 0.2475, indicating post-disclosure exploitation interest that later subsided.

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.
