Exploitation Conditions

Exploitation requires the target WordPress site to have the Freeton WP plugin (version ≤1.0.0) installed and active, and the attacker must know the email address of an existing user - ideally an administrator - since the flaw lets them authenticate as any user whose email they know by abusing the plugin's broken activation-code validation. No credentials, no privileges, and no user interaction are required (PR:N/UI:N), and it works against default plugin behavior. The only practical limiting factors are (1) the plugin must be installed, which narrows exposure given its small footprint, and (2) the attacker needs a valid target email, which is typically easy to obtain via WordPress author enumeration or public site content.

Impact

Multiple signals align toward genuine priority for environments running this specific plugin. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) describes a remote, unauthenticated, low-complexity authentication bypass with full confidentiality/integrity/availability impact (C:H/I:H/A:H), scored 9.8 - consistent with the description's claim that an attacker can log in as any user, including administrators, which equals full site takeover. POC/exploit code is reported as publicly available (via WPScan), raising practical exploitability above a theoretical high-CVSS issue. No EPSS score was provided in the input, and the CVE is NOT listed in CISA KEV, so there is no confirmation of active, widespread exploitation - the risk is real but currently 'exploitable and public' rather than 'confirmed exploited.' No SSVC decision data was supplied. One mild mitigating nuance: exploitation requires the attacker to know a valid user/admin email address, though WordPress admin emails are frequently guessable or enumerable, so this is a weak barrier. Net: for any site running Freeton WP ≤1.0.0 this is a top-priority patch/removal item; broad fleet risk is tempered only by the plugin's apparently small deployment footprint.

Exploit ScenarioDerived

An unauthenticated attacker identifies the email address of an administrator (often exposed via author pages, WHOIS, or enumeration) on a WordPress site running Freeton WP ≤1.0.0. Because the plugin fails to properly validate the activation code during authentication, the attacker submits a login request for that email and is granted an authenticated administrator session without valid credentials. Public exploit code exists, lowering the skill required to carry this out.

AnalysisAIv1 – Oct 11, 2026

Authentication bypass in the Freeton WP WordPress plugin through version 1.0.0 lets unauthenticated attackers log in as any existing user, including administrators, using only that user's email address, because the plugin does not correctly validate the activation code used during authentication. The flaw is rated 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, CWE-287) and requires no credentials and no user interaction; publicly available exploit code exists (referenced from the WPScan entry), and no CISA KEV listing indicates confirmed active exploitation. Exposure is limited to WordPress sites where the plugin is installed and active - an important qualifier given the plugin's small footprint - but for those sites the practical barrier is only knowledge of a valid account email, which is commonly obtainable through WordPress author enumeration.

RemediationAI

No patched release is identified in the available intelligence - the only references are the WPScan vulnerability entry and the NVD record, neither of which names an upgrade version, so there is no confirmed fixed release to cite. The most reliable action is therefore to deactivate and remove the Freeton WP plugin from all WordPress installations (accepting the loss of whatever functionality it provides), and to treat any site that ran it as potentially compromised by auditing user accounts, sessions and administrator activity. If removal is not immediately possible, compensating controls include blocking or restricting the plugin's activation-code authentication endpoint at the reverse proxy or WAF (blocks legitimate activation/login-by-code flows for that plugin), preventing username and email disclosure by disabling author enumeration (author archives, /?author=N redirects, and the /wp-json/wp/v2/users REST endpoint) so attackers cannot harvest the email addresses the exploit depends on, and enforcing strong unique credentials plus mandatory password resets and session invalidation for all administrator accounts. Note that none of these controls fixes the validation flaw itself; the plugin's own code remains exploitable until it is patched or removed. Monitor web server and plugin logs for authentication attempts referencing activation-code parameters or unexpected successful logins, and consult the WPScan advisory (https://wpscan.com/vulnerability/b26e6b42-0c9f-4b6b-ac2c-2e452038288b/) for any later patched-version notice.

Technical ContextAI · show details

The root cause is CWE-287 (Improper Authentication) inside the Freeton WP plugin's login flow: the plugin treats an activation code as a sufficient credential and fails to bind or verify that code against the specific user being authenticated, so a caller who supplies a known email address can complete authentication as that account. This is a classic broken-credential-verification pattern in a WordPress plugin, where a custom passwordless/activation path bypasses WordPress's own authentication and capability checks. The CPE string recorded is cpe:2.3:a:unknown:freeton_wp:*:*:*:*:*:*:*:*, with the vendor still recorded as "unknown", indicating the plugin is not formally mapped in the NVD CPE dictionary and that inventory must be done by scanning installed plugins rather than relying on vendor/product matching. The CVSS vector confirms remote, network-reachable exploitation with no privileges (PR:N) and no user interaction (UI:N), and full confidentiality, integrity and availability impact (C:H/I:H/A:H) - consistent with an attacker obtaining an administrator session. The vulnerability class is tracked under ENISA EUVD ID EUVD-2026-96762 and was reported by WPScan.

Executive ViewAI

Why It Matters

The Freeton WP WordPress plugin through version 1.0.0 contains a critical unauthenticated authentication bypass that lets attackers log in as any existing user, including administrators, if they know the user's email address; publicly available exploit code exists and no vendor-released patch has been identified. Organizations with this plugin active on public-facing WordPress sites face potential full site takeover, data theft, and service disruption, making immediate containment necessary. Although the plugin's small footprint limits exposure, the business impact is severe for any affected site because exploitation requires no credentials and no user interaction.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis; interim mitigations include deactivating or removing the Freeton WP plugin (through version 1.0.0), restricting public access to affected WordPress sites, applying WAF virtual patching to block the vulnerable authentication flow, forcing password resets and reviewing logs for unauthorized logins, and monitoring for new or modified administrator accounts.
