Network-accessible with no authentication or user interaction; C:L rather than C:H because each exploit yields targeted data for one known victim email, not systemic access.

The WP DSGVO Tools (GDPR) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.1.39. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to supply an arbitrary victim email address and trigger immediate SAR processing via the process_now and is_ajax parameters, receiving tokenized download links (zip_link, pdf_link) in the HTTP response that expose the victim's personal data - including WordPress account details, comment author names, email addresses, IP addresses, and comment content - without any proof of ownership. The nonce used for the CSRF check is publicly rendered by the SAR shortcode form and is shared across all anonymous visitors, meaning any unauthenticated attacker can trivially obtain a valid nonce and bypass this gate entirely.
AnalysisAI
Unauthenticated personal data exfiltration in WP DSGVO Tools (GDPR) plugin for WordPress (≤3.1.39) allows any remote attacker to trigger immediate Subject Access Request (SAR) fulfillment for an arbitrary victim email, receiving tokenized download links in the HTTP response that expose WordPress account details, comment history, email addresses, and IP addresses. The plugin's CSRF nonce - the only gate protecting this action - is publicly rendered by the SAR shortcode form and shared across all anonymous visitors, rendering it entirely ineffective as an access control mechanism. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the following specific conditions to all be true simultaneously: the target site must have WP DSGVO Tools (GDPR) version 3.1.39 or earlier installed and active; at least one publicly accessible page or post on the site must embed the Subject Access Request shortcode (which renders the shared nonce in the HTML); and the attacker must know or be able to enumerate a valid email address belonging to a registered WordPress user or comment author on that site. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD/Wordfence CVSS base score of 5.3 (Medium, AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) accurately captures the technical ease of exploitation but arguably understates the sensitivity of the exposed data. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker visits the target WordPress site, locates a page embedding the SAR shortcode form, and extracts the publicly available nonce value from the rendered HTML. They then submit a crafted POST request to the plugin's AJAX handler with process_now=1, is_ajax=1, and a target victim's email address; the server immediately processes the SAR and returns zip_link and pdf_link download URLs in the HTTP response, allowing the attacker to download the victim's complete personal data package without any authentication or proof of ownership. |
| Remediation | An upstream fix changeset has been committed to the WordPress plugin repository (https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3574362%40shapepress-dsgvo&new=3574362%40shapepress-dsgvo), but a specific patched tagged release version is not confirmed in the available data - administrators should verify the current version in the WordPress plugin directory and update to any release beyond 3.1.39 once confirmed patched. … Detailed patch versions, workarounds, and compensating controls in full report. |
