CVE-2026-110002: Snazzy Social Media Feed Critical Flaw Lets Auth Users Run Code

A critical vulnerability in the Snazzy Social Media Feed WordPress plugin allows authenticated attackers to execute remote code, according to National Vulnerability Database records. The flaw, identified as CVE-2026-110002, affects all versions of the plugin up to and including 2.5. Organizations using this tool for social media integration should assess their exposure to this arbitrary file upload issue.

The issue arises from a standalone script named save-to-cache.php, which operates without loading the standard WordPress environment. This script lacks essential authentication, capability, and nonce checks. Furthermore, it applies insufficient sanitization to the pluginURL parameter before writing it to a web-executable PHP file. Attackers can exploit this gap to upload files that may be executable, making remote code execution possible.

Technical context

The save-to-cache.php script is directly reachable without triggering WordPress bootstrap processes. The only filter applied to the pluginURL value is FILTER_SANITIZE_URL. This filter preserves characters necessary to craft valid PHP payloads. Consequently, malicious code is written verbatim into cached-content/cached-feed.php. Once written, the payload becomes immediately executable via a single GET request. This weakness is categorized under CWE-434, representing an improper neutralization of special elements in output.

Affected organizations

The vulnerability impacts any WordPress site running Snazzy Social Media Feed version 2.5 or earlier. Attackers need only subscriber-level access or higher to exploit the flaw. This low barrier to entry means compromised employee accounts or low-privilege user logins can be leveraged for full system compromise. Organizations using this plugin for marketing or social feeds should verify their current version immediately.

Defender's checklist

Security teams should audit WordPress installations for the Snazzy Social Media Feed plugin. Identify all instances of versions up to 2.5. Monitor server logs for unusual activity on save-to-cache.php or cached-content directories. Review user permissions to ensure subscriber accounts have the minimum necessary access. Check for unauthorized PHP files in cache directories.

Operational impact

When a plugin allows low-privilege users to execute code, operational teams must assess supplier risk. Departments should verify if marketing or social media tools have undergone recent security reviews. IT leaders need to determine if current incident response plans cover plugin-level compromises. Staff responsible for user management should audit subscriber accounts for unusual login patterns. Communication teams must prepare internal messaging about potential service disruptions. Vendor support contracts should be reviewed to ensure timely patches are delivered. Cross-departmental collaboration is essential to identify all affected systems quickly.

Background: Incident response plans

An incident response plan is a documented procedure for detecting, containing, and recovering from security breaches. It defines roles, communication channels, and technical steps to minimize damage, preserve evidence, and restore normal operations quickly.
