CVE-2026-14309 Overview
CVE-2026-14309 is an authentication bypass vulnerability in the Chat On Desk Order Notifications WordPress plugin before version 1.0.9. The plugin fails to verify that a one-time password (OTP) has been validated before processing a password-reset request. Unauthenticated attackers can reset the password of arbitrary users, including administrators, when SMS OTP password reset is enabled. Successful exploitation results in full account takeover of the targeted WordPress site.
Critical Impact
Unauthenticated attackers can take over administrator accounts on affected WordPress sites, gaining complete control over site content, users, and installed plugins.
Affected Products
- Chat On Desk Order Notifications WordPress plugin versions prior to 1.0.9
- WordPress installations with the plugin installed and SMS OTP password reset enabled
- Any downstream site relying on the plugin's password-reset flow for user authentication

Technical Details for CVE-2026-14309
Vulnerability Analysis
The vulnerability is classified under [CWE-287] (Improper Authentication). The plugin exposes an SMS-based OTP password-reset feature. During the reset workflow, the server accepts a password-reset request without confirming that the associated OTP was successfully validated. This authentication logic flaw enables an attacker to submit a new password for any username, including administrator accounts, without possessing the OTP delivered to the legitimate user.
Because the flaw resides in server-side workflow enforcement, client-side validation cannot mitigate the issue. Any WordPress site running an affected version with SMS OTP password reset enabled is exposed to unauthenticated account takeover over the network.
Root Cause
The root cause is a missing state check between the OTP validation step and the password-reset processing step. The plugin treats the two steps as independent operations rather than enforcing that a successful OTP validation is a prerequisite for accepting a new password. This is a classic broken authentication pattern where the authorization boundary depends on a preceding step that is never verified.
Attack Vector
The attack vector is network-based and requires no authentication or user interaction. An attacker submits a crafted password-reset request naming the target account, then supplies a new password directly to the reset endpoint. The plugin processes the reset without confirming the OTP challenge was completed successfully. The attacker then logs in with the newly set credentials and inherits the target's privileges.
No verified proof-of-concept code is publicly available. For technical details, refer to the WPScan Vulnerability Report.
Detection Methods for CVE-2026-14309
Indicators of Compromise
- Unexpected password-reset events in WordPress logs for administrator or privileged accounts
- Successful logins from unfamiliar IP addresses shortly after a password change
- New administrator accounts, plugin installations, or theme edits following a reset event
- Requests to the plugin's password-reset endpoint that lack a preceding successful OTP validation event
Detection Strategies
- Monitor WordPress user_meta and wp_users tables for password hash changes not initiated by the account owner
- Correlate password-reset HTTP requests with OTP-issuance events to identify resets that skipped validation
- Alert on password changes for administrator roles originating from IP addresses not previously seen for that user
Monitoring Recommendations
- Ingest WordPress access logs and authentication events into a centralized logging platform for correlation
- Enable auditing plugins that record password-reset attempts, OTP issuance, and administrative role changes
- Review web server logs for repeated POST requests to plugin reset endpoints from single source IPs
How to Mitigate CVE-2026-14309
Immediate Actions Required
- Update the Chat On Desk Order Notifications plugin to version 1.0.9 or later on all WordPress sites
- Force a password reset for all administrator and privileged accounts as a precautionary measure
- Review recent password-reset events and administrator logins for signs of prior exploitation
- Audit installed plugins, themes, and user accounts for unauthorized modifications
Patch Information
The vendor addressed the vulnerability in Chat On Desk Order Notifications version 1.0.9. The fix enforces validation of the OTP state before allowing a password-reset request to complete. Refer to the WPScan Vulnerability Report for advisory details.
Workarounds
- Disable the SMS OTP password-reset feature until the plugin is updated to 1.0.9 or later
- Deactivate the Chat On Desk Order Notifications plugin if the OTP reset feature cannot be disabled
- Restrict access to WordPress password-reset endpoints using a web application firewall (WAF) rule
- Enforce multi-factor authentication for administrator accounts through a separate, unaffected plugin
