Weakness	CWE CWE-862 OWASP Top 10:2025 A01:2025 - Broken Access Control ASVS 5.0 V8 - Authorization Authorization checks on every request MITRE ATT&CK 1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	No special configuration is required beyond having the Name Directory plugin (version n/a through 1.34.2) installed and active on a WordPress site; the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates remote, unauthenticated exploitation with no user interaction against default installs. The practical limiting factors are the narrow impact (low confidentiality only, no integrity or availability) and the plugin's limited deployment footprint - exploitation yields unauthorized access to directory data exposed via the affected shortcode rather than site compromise. Upgrading past 1.34.2 removes the exposure.
Impact	This is a moderate-severity Missing Authorization flaw (CWE-862) in the Name Directory WordPress plugin, scored CVSS 5.3 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N - remote, low-complexity, unauthenticated, but limited to low confidentiality impact with no integrity or availability effect. The Patchstack reference titles this an 'arbitrary shortcode execution vulnerability,' which aligns with broken access control allowing an unauthenticated actor to invoke plugin functionality (shortcode rendering) they should not reach; the low C impact suggests the practical outcome is unauthorized information disclosure rather than code execution on the host. No EPSS score, CISA KEV listing, or public POC was supplied in the input, so there is no signal of active exploitation or weaponization. The signals are internally consistent (unauthenticated network vector matches a missing-authorization WordPress issue), but the overall priority is tempered: the C:L/I:N/A:N impact and modest plugin footprint make this a routine patch-when-convenient item rather than an emergency, absent exploitation evidence. SSVC-style framing: exploitation none-observed, automatable likely (unauthenticated web request), technical impact partial.
Exploit ScenarioDerived	An unauthenticated attacker sends a crafted HTTP request to a WordPress site running Name Directory ≤1.34.2, invoking a plugin shortcode or endpoint without the authorization check that should gate it. This lets them trigger directory functionality and read data they should not have access to. No public exploit code was identified at time of analysis, though the low attack complexity and lack of authentication make exploitation straightforward.

AnalysisAIv1 – Oct 05, 2026

Missing authorization in the WordPress Name Directory plugin (through version 1.34.2) lets remote, unauthenticated attackers reach functionality and directory data that should require higher privileges or proper access-control checks. The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N reflects low-complexity, unauthenticated exploitation against default installs, with impact confined to low confidentiality loss and no integrity or availability effect, so the realistic outcome is unauthorized disclosure of directory entries rather than site takeover. No public exploit code has been identified at time of analysis and there is no CISA KEV listing; the primary practical exposure is limited to sites running the vulnerable plugin.

RemediationAI

No fixed version number is documented in the available advisory data for CVE-2026-104397, so the immediate action is to upgrade the Name Directory plugin beyond 1.34.2 as soon as a patched release is published, after checking the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/name-directory/vulnerability/wordpress-name-directory-plugin-1-34-2-arbitrary-shortcode-execution-vulnerability?_s_id=cve for the vendor-confirmed fixed release; until then, treat 1.34.2 and earlier as vulnerable. Where an upgrade is not immediately possible, deactivate the Name Directory plugin if its directory functionality is not business-critical - this fully removes exposure but disables the feature for legitimate users. As a narrower compensating control, restrict access to the pages and endpoints that render the plugin's shortcode output via server-level rules or a WAF that requires authentication for those paths, accepting that this will also block anonymous visitors who legitimately use the public directory. Because the assessed impact is limited to low confidentiality loss with no integrity or availability effect, prioritization can follow routine plugin-update cadence rather than emergency change procedures, but the update should still be applied promptly given the unauthenticated, no-interaction exploitation profile.

Technical ContextAI · show details

The flaw is a CWE-862 Missing Authorization condition in the Name Directory plugin for WordPress, tracked as CVE-2026-104397. The CPE entry cpe:2.3:a:jeroen_peters:name_directory:*:*:*:*:*:*:*:* confirms that all released versions up to and including 1.34.2 are in scope. WordPress plugins commonly expose custom functionality through shortcodes and AJAX/REST handlers; where such handlers omit a capability check or nonce validation, requests from unauthenticated visitors are processed with the site's own privileges. The supplied advisory reference, whose URL slug refers to 'arbitrary shortcode execution' for Name Directory 1.34.2, indicates the missing control is tied to how the plugin processes shortcode-driven input rather than to a memory-safety or injection flaw - the exposed behavior is the ability to trigger protected plugin logic without authorization, consistent with the assessed vector showing only a low confidentiality impact (C:L) and no integrity or availability change. The CVSS vector (PR:N, UI:N, AV:N, AC:L) establishes that exploitation requires no authentication and no victim interaction, while the S:U scope and unchanged I/A metrics bound the damage to reading data the attacker should not be able to access.
