CVE Details
- CVE ID: CVE-2026-14559
- Affected component: teddy-bear-customize-addon WordPress plugin
- Affected versions: versions through 1.0.5 (versions <= 1.0.5)
- Published: September 11, 2026 at 7:16:45 AM UTC
- Last modified: September 11, 2026 at 11:16:53 AM UTC
- CVSS v3.1: Base score 9.8, Severity: CRITICAL, Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H - Authentication / privileges / user interaction: No privileges required, no user interaction required (PR: NONE, UI: NONE)
- Primary impact: Confidentiality: HIGH; Integrity: HIGH; Availability: HIGH
- CWE: CWE-287 (Improper Authentication)
Technical Details
According to the advisory, the plugin does not verify a user’s password before authenticating them. As a result, an attacker can supply only a registered user’s email address and be authenticated as that user. The underlying weakness is an authentication bypass caused by missing or incorrect password verification logic (CWE-287).
No specific plugin functions, REST API endpoints, or code paths are named in the provided data. The described impact is limited to allowing unauthenticated login as any registered user, including administrators, by providing only the user’s email address.
How This Could Impact Your Website
In a typical site with multiple users, this vulnerability could be used by an external attacker who knows or can guess internal email addresses. For example:
- A site owners administrator account could be accessed if the owners email is known, allowing the attacker to change site settings or install plugins.
- An internal staff member or editor could be impersonated, exposing drafts, private pages, or contact lists tied to that account.
- An external contractor or contributor with elevated permissions could be targeted to gain access to restricted content or user data.
Practical consequences include exposure of internal user email addresses and an increased risk of targeted phishing or social engineering against those users. If youre unsure whether your site is affected or how to assess your current user roles and plugins, it may be worth having a professional review.
Recommended Actions
- Update the affected plugin as soon as a patched version is available.
- Review and reduce unnecessary user roles and permissions, especially accounts with contributor or higher privileges.
- Enforce strong, unique passwords and enable two-factor authentication for editor and administrator accounts.
- Remove unused or unmaintained plugins from your site.
- Monitor site activity and login records for unusual behavior, including logins from unfamiliar IP addresses or unexpected account access.
