The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires that the target account has an empty or unset sb_password_forget_token user meta value - the default state for any user who has not an active pending reset - allowing an empty attacker-supplied token to satisfy the check in nokri_reset_password(). The attacker must reach the theme's password-reset handler over the network and know or guess the target account (e.g. the administrator username). Limiting factors are minimal: no authentication, no user interaction, and no special configuration are needed beyond having the Nokri theme (version ≤ 1.6.6) installed and active; the main practical constraint is that an account which currently has a legitimately issued, non-empty reset token pending would not match an empty token.

Impact

This should be treated as a high-priority issue. The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H reflects remote, unauthenticated, low-complexity exploitation with no user interaction and full compromise of confidentiality, integrity, and availability at the application level - consistent with the described logic flaw. Because exploitation requires only submitting an empty token against an account whose reset token is unset (the common default state), the attack is trivially automatable and well-suited to mass scanning of WordPress sites, which typically drives high real-world exploitation probability even where an EPSS score is not provided in this input. No EPSS value, POC, or CISA KEV entry is included, so there is no confirmation of active exploitation yet; the risk here is driven by the low barrier to exploit rather than by observed campaigns. Any operator running this theme, from small single-site deployments to larger hosting fleets, should treat administrator account takeover as an imminent threat and prioritize remediation over waiting for exploitation telemetry.

Exploit ScenarioDerived

An attacker enumerates or guesses a valid username (such as the default admin), then submits the theme's password-reset request with an empty reset token and a new password of their choosing. Because the empty token matches the target's unset sb_password_forget_token meta, the reset succeeds and the attacker logs in as that user; given AV:N/AC:L/PR:N/UI:N this can be scripted against many sites at once. No public POC is identified at time of analysis.

AnalysisAIv1 – Sep 01, 2026

Unauthenticated account takeover in the Nokri - Job Board WordPress theme (versions through 1.6.6) lets remote attackers reset any user's password, including administrators. The flaw stems from the nokri_reset_password() function accepting an empty reset token that matches the empty or unset sb_password_forget_token user meta value, so no valid token is ever needed. Reported by Wordfence and rated CVSS 9.8; no public exploit or CISA KEV listing is identified at time of analysis.

RemediationAI

No vendor-released patch version is identified in the provided data, so a specific upgrade target cannot be cited; monitor the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/b03b7ea8-6485-495d-b815-2b7b882a75a2) and the vendor site (https://nokriwp.com/) for a release above 1.6.6 and update as soon as it is published. As compensating controls until a fix is available, restrict or disable the theme's front-end password-reset endpoint (for example via web-server rules or a security plugin blocking the reset action), deploy a WordPress WAF rule to reject reset requests carrying an empty or missing token parameter, and force a password reset plus review of administrator accounts for unexpected changes. Enforcing strong two-factor authentication on all administrator accounts limits the impact of a stolen password, though it does not by itself close the reset flaw; blocking the reset flow may inconvenience legitimate users who need self-service password recovery.

Technical ContextAI · show details

The affected software is a commercial WordPress theme (ScriptsBundle's Nokri, CPE cpe:2.3:a:scriptsbundle:nokri_-_job_board_wordpress_theme) that adds job-board and user-account functionality including a custom password-reset flow. The root cause maps to CWE-269 (Improper Privilege Management): the password-reset handler compares an attacker-supplied token against the sb_password_forget_token user meta without first verifying the token is non-empty and was actually issued. Because WordPress user meta returns an empty string for unset keys, an empty submitted token equals the stored empty value, so the equality check passes for any account that has never initiated a reset. This is effectively a broken authentication/authorization check in the reset routine rather than a memory-safety or injection bug.

DescriptionCVE.org

The Nokri - Job Board WordPress Theme for WordPress is vulnerable to Privilege Escalation via Account Takeover in all versions up to, and including, 1.6.6. This is due to insufficient reset token validation in the nokri_reset_password() function, which allows empty attacker-supplied reset tokens to match empty or unset sb_password_forget_token user meta values. This makes it possible for unauthenticated attackers to reset the password of any user, including administrators, and gain access to their account.

Executive ViewAI

Why It Matters

Nokri Job Board WordPress theme through version 1.6.6 contains a critical account takeover vulnerability requiring no authentication-attackers can reset any user password, including administrator accounts. Organizations deploying this theme face immediate risk of complete site compromise, including data theft and malware injection.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis. Implement interim mitigations: disable the Nokri theme or restrict the password reset endpoint via WAF/server rules; enforce multi-factor authentication on all WordPress administrator and editor accounts; enable comprehensive WordPress security logging with real-time alerts for password resets and admin modifications; restrict wp-admin access to known organizational IP ranges where feasible; deploy a WordPress security plugin (Wordfence, Sucuri) to monitor for unauthorized administrative changes.
