CVE-2025-22354 Overview
CVE-2025-22354 is a DOM-based Cross-Site Scripting (XSS) vulnerability in the Code Themes Digi Store WordPress theme. The flaw stems from improper neutralization of input during web page generation, classified under [CWE-79]. It affects all versions of Digi Store up to and including 1.1.4.
An authenticated attacker with low privileges can inject malicious scripts that execute in a victim's browser session after user interaction. Successful exploitation can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim within the WordPress site.
Critical Impact
Attackers can execute arbitrary JavaScript in the browser of any user who interacts with a crafted payload, compromising confidentiality and integrity of the affected WordPress site.
Affected Products
- Code Themes Digi Store WordPress theme versions up to and including 1.1.4
- WordPress installations using the vulnerable Digi Store theme
- Any user sessions interacting with pages rendered by the vulnerable theme

Technical Details for CVE-2025-22354
Vulnerability Analysis
The vulnerability is a DOM-based XSS flaw in the Digi Store theme's client-side JavaScript. The theme processes attacker-controlled input and writes it into the Document Object Model (DOM) without adequate sanitization or encoding. Because the injection occurs in the browser rather than server-side, traditional web application firewall rules that inspect HTTP response bodies may not detect the payload.
Exploitation requires an authenticated user with at least low-level privileges to submit a crafted payload, and a victim must interact with the resulting content. The scope changes upon successful exploitation, meaning the script can affect resources beyond the theme's own security boundary, such as authenticated WordPress admin sessions.
Root Cause
The root cause is missing output encoding in client-side JavaScript that constructs HTML from user-supplied values. The theme concatenates untrusted input into DOM sinks such as innerHTML, document.write, or jQuery .html() without escaping angle brackets, quotes, or event handler attributes. Refer to the Patchstack advisory for technical specifics.
Attack Vector
The attack is delivered over the network. An authenticated attacker injects a payload containing script content into a field processed by the theme. When another user views the affected page, the browser parses the malicious markup and executes the attacker's JavaScript in the victim's origin context.
No verified public proof-of-concept code is available. See the Patchstack advisory linked above for reproduction details.
Detection Methods for CVE-2025-22354
Indicators of Compromise
- Unexpected <script> tags, javascript: URIs, or event handler attributes (onerror, onload) stored in WordPress post meta, comments, or theme option tables
- Outbound browser requests from authenticated WordPress sessions to unfamiliar domains after loading Digi Store pages
- Session cookies or nonces appearing in web server referer logs of external hosts
Detection Strategies
- Audit WordPress database tables (wp_options, wp_postmeta, wp_posts) for HTML markup containing script tags or JavaScript event handlers submitted by low-privileged accounts
- Inspect browser DevTools console output on pages rendered by the Digi Store theme for unexpected script execution
- Deploy Content Security Policy (CSP) reporting to capture inline script violations originating from theme templates
Monitoring Recommendations
- Monitor WordPress audit logs for content edits by Contributor, Author, or Subscriber accounts targeting theme-controlled fields
- Alert on new administrator account creation or privilege changes following suspicious content submissions
- Track anomalous JavaScript execution patterns and outbound connections from browsers accessing the WordPress site
How to Mitigate CVE-2025-22354
Immediate Actions Required
- Update the Code Themes Digi Store theme to a version later than 1.1.4 once the vendor publishes a patched release
- Restrict content submission privileges to trusted user roles and review recent submissions from low-privileged accounts
- Enforce a strict Content Security Policy that disallows inline scripts and untrusted script sources
Patch Information
At the time of publication, the vulnerability affects Digi Store versions up to 1.1.4. Consult the Patchstack advisory for the latest fixed version and vendor guidance.
Workarounds
- Deactivate the Digi Store theme and switch to an unaffected theme until a patched version is released
- Deploy a WordPress-aware web application firewall with virtual patching rules for XSS payloads targeting theme parameters
- Apply a Content Security Policy header such as Content-Security-Policy: default-src 'self'; script-src 'self' to limit script execution surface
