AnalysisAI

GiveWP WordPress plugin before 4.16.3 exposes sensitive donor privacy data through an unauthenticated REST API endpoint that returns recurring-donation records without access controls. Any unauthenticated remote party can enumerate donor names and subscription details for donors who explicitly chose to give anonymously, directly violating donor privacy expectations. A publicly available exploit exists per WPScan reporting, though EPSS sits at the 5th percentile, suggesting limited opportunistic exploitation at time of analysis. No active exploitation is confirmed via CISA KEV.

Technical ContextAI

GiveWP is a WordPress plugin providing donation management functionality, including recurring (subscription-based) donation processing. The vulnerability resides in a REST API endpoint registered by the plugin that surfaces recurring-donation records. WordPress REST API endpoints are publicly reachable by default unless explicitly protected with permission callbacks; CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) describes the root cause: the endpoint lacked a proper capability check or authentication requirement, allowing unauthenticated HTTP clients to query it. Affected CPE is cpe:2.3:a:unknown:givewp:*:*:*:*:*:*:*:* covering all GiveWP versions prior to 4.16.3. The data returned includes donor names and subscription details, which is particularly sensitive since these records correspond to donors who opted for anonymous giving.

RemediationAI

Upgrade GiveWP to version 4.16.3 or later, which is the vendor-released patched version confirmed by WPScan and the EUVD advisory. The fix can be applied via the standard WordPress plugin update mechanism (Dashboard > Plugins > Update Available). If immediate patching is not possible, a compensating control is to disable REST API access for unauthenticated users at the WordPress or web server level (e.g., via the Disable REST API plugin or nginx/Apache rules blocking /wp-json/ for anonymous requests) - note this may break other plugins or themes that depend on public REST API access. Alternatively, restricting network access to the WordPress installation to authenticated sessions only (e.g., via a WAF rule or HTTP Basic Auth at the server level) would prevent unauthenticated enumeration.
