CVE-2026-22450: 
WordPress vulnerability analysis and mitigation

CVE-2026-22450 is a Missing Authorization vulnerability in the "Don Peppe" WordPress theme developed by Select-Themes. It allows authenticated attackers with low-level privileges to exploit incorrectly configured access control security levels, potentially making unauthorized modifications. The vulnerability affects Don Peppe versions up to and including 1.3. It was reported by Patchstack and published on January 22, 2026, with a CVSS v3.1 base score of 4.3 (Medium) (Patchstack, NVD).

The root cause is classified as CWE-862 (Missing Authorization), meaning the theme fails to properly verify whether an authenticated user has the appropriate permissions before executing certain actions. An attacker with a low-privileged account (e.g., a subscriber or contributor role on a WordPress site) can send crafted network requests to trigger functionality that should be restricted to higher-privileged users. No user interaction is required beyond authentication, and attack complexity is low. The vulnerability was assigned and disclosed by Patchstack (Patchstack, NVD).

Successful exploitation results in a limited integrity impact — authenticated low-privileged users can perform unauthorized actions within the WordPress site that should be restricted to administrators or editors. There is no direct confidentiality or availability impact based on the CVSS scoring. The scope is limited to the affected WordPress installation, with no evidence of lateral movement potential beyond the site's content management functions (NVD, Patchstack).

The vulnerability requires a low-privileged authenticated account on the target WordPress site, making it less trivially exploitable than unauthenticated flaws. No public proof-of-concept exploit code or in-the-wild exploitation has been reported. The EPSS score is approximately 0.017%, indicating a very low probability of exploitation in the near term. It does not appear in the CISA Known Exploited Vulnerabilities (KEV) catalog (NVD).

Users of the Don Peppe WordPress theme should update to a version beyond 1.3 if a patched release is available from Select-Themes. If no patch is yet available, site administrators should restrict user registration and minimize the number of low-privileged accounts on the WordPress installation. Monitoring WordPress admin logs for unexpected actions performed by subscriber or contributor-level accounts is also advisable (Patchstack, NVD).
