CVE-2025-58646 Overview
CVE-2025-58646 is a stored cross-site scripting (XSS) vulnerability in the chtombleson Mobi2Go WordPress plugin. The flaw affects all Mobi2Go versions up to and including 1.0.0. Attackers with high privileges can inject malicious JavaScript that persists within the plugin's output and executes in the browser of any user who views the affected page. Because the attack changes security scope, the impact reaches beyond the vulnerable component itself. The vulnerability is tracked under [CWE-79], improper neutralization of input during web page generation.
Critical Impact
Successful exploitation enables persistent script execution in visitor browsers, allowing session theft, redirection, and unauthorized actions performed under the victim's identity.
Affected Products
- chtombleson Mobi2Go WordPress plugin versions up to and including 1.0.0
- WordPress sites running the Mobi2Go plugin without the vendor patch
- Administrative user sessions interacting with plugin-generated pages

Technical Details for CVE-2025-58646
Vulnerability Analysis
The Mobi2Go plugin fails to neutralize user-supplied input before rendering it into web pages. An authenticated attacker with elevated privileges can submit payloads containing HTML or JavaScript through plugin input fields. The server stores these payloads and returns them unchanged when other users load the affected pages. Because the injection persists, every subsequent visitor triggers the payload without further attacker interaction. The scope change component in the CVSS vector indicates that exploitation impacts resources beyond the vulnerable plugin, such as the surrounding WordPress session context.
Root Cause
The plugin performs insufficient input sanitization and output encoding on data written to the WordPress database and later echoed into HTML responses. Missing calls to WordPress escaping helpers such as esc_html(), esc_attr(), or wp_kses() allow raw markup to flow from storage into rendered pages. This pattern is a classic instance of [CWE-79].
Attack Vector
Exploitation requires network access to the WordPress administrative interface and an authenticated account with high privileges. The attacker submits a crafted payload through a plugin form or configuration field. User interaction is required, meaning a victim must load the page containing the stored payload. Once rendered, the script executes in the victim's browser under the site's origin. The vulnerability is documented in the Patchstack Mobi2Go XSS advisory.
Detection Methods for CVE-2025-58646
Indicators of Compromise
- Unexpected <script>, <iframe>, or on*= event handler attributes stored in Mobi2Go plugin configuration records within wp_options or plugin-specific tables
- Outbound requests from administrator browsers to unknown domains shortly after loading Mobi2Go-rendered pages
- New or modified WordPress administrator accounts created after plugin page visits
- Session cookies or authentication tokens appearing in web server access logs of unfamiliar hosts
Detection Strategies
- Review database entries associated with the Mobi2Go plugin for HTML markup or JavaScript keywords
- Deploy Content Security Policy (CSP) reporting to capture inline script violations on plugin pages
- Correlate WordPress audit logs of privileged account activity with subsequent DOM anomalies
- Scan rendered pages for stored payloads using automated XSS detection tooling
Monitoring Recommendations
- Enable WordPress activity logging for plugin configuration changes and administrator actions
- Forward web server and application logs to a centralized analytics platform for anomaly detection
- Alert on administrator session anomalies including unexpected geolocation or user-agent changes
- Monitor Patchstack and WordPress plugin repository advisories for follow-up updates to Mobi2Go
How to Mitigate CVE-2025-58646
Immediate Actions Required
- Deactivate the Mobi2Go plugin on production WordPress sites until a patched release is verified
- Audit stored plugin data for injected scripts and remove any malicious content before reactivation
- Rotate WordPress administrator credentials and invalidate active sessions if compromise is suspected
- Restrict access to the WordPress admin interface using IP allowlisting or reverse proxy authentication
Patch Information
No fixed version is currently identified in the referenced advisory. The vulnerability affects Mobi2Go through version 1.0.0. Consult the Patchstack Mobi2Go XSS advisory for updates and coordinate with the plugin maintainer for a patched release.
Workarounds
- Remove the Mobi2Go plugin entirely if a patched version is unavailable and business requirements permit
- Enforce a strict Content Security Policy that disallows inline scripts on WordPress admin and plugin pages
- Apply a web application firewall (WAF) rule set to filter script injection patterns in plugin form submissions
- Limit the number of accounts with administrator privileges to reduce the attacker population
