CVE-2025-69318: JobWP <= 2.4.5 – Unauthenticated Stored Cross-Site Scripting (jobwp)

CVE ID CVE-2025-69318
Plugin jobwp
Severity High (CVSS 7.2)
CWE 79
Vulnerable Version 2.4.5
Patched Version 2.4.6
Disclosed January 20, 2026

Analysis Overview

Atomic Edge analysis of CVE-2025-69318:
The JobWP WordPress plugin version 2.4.5 and earlier contains a stored cross-site scripting (XSS) vulnerability. The flaw exists in the plugin’s job application resume file upload functionality. Unauthenticated attackers can inject arbitrary JavaScript payloads that execute in the context of an administrator’s session when viewing the application list page. The CVSS score of 7.2 reflects the high impact of stored XSS in a WordPress admin context.

The root cause is insufficient input sanitization for the resume file name parameter during the job application submission process. In the vulnerable code at `jobwp/core/job_application.php` line 22, the plugin directly concatenates `$_FILES[‘jobwp_upload_resume’][‘name’]` with a unique identifier without proper sanitization. The user-controlled filename is then stored in the database and later rendered unsafely in the admin panel at `jobwp/admin/view/application_list.php` line 62-65, where the filename is output without proper escaping in an HTML anchor tag’s href attribute.

Exploitation occurs through the public job application submission form. Attackers craft a malicious filename containing JavaScript payloads, such as `javascript:alert(document.cookie).pdf` or similar XSS vectors. When an administrator views the application list page at `/wp-admin/admin.php?page=jobwp-applications`, the malicious filename is rendered directly into the page’s HTML. The payload executes immediately in the administrator’s browser context, allowing session hijacking, administrative actions, or further site compromise.

The patch addresses the vulnerability at two points. First, in `jobwp/core/job_application.php`, the filename is sanitized using `sanitize_file_name()` before storage. Second, in `jobwp/admin/view/application_list.php`, the output is properly escaped using `esc_url()` when generating the download link. These changes ensure that user input is both sanitized before storage and escaped before output, following WordPress security best practices for defense in depth.

Successful exploitation allows unauthenticated attackers to execute arbitrary JavaScript in WordPress administrator sessions. This can lead to complete site takeover through administrative credential theft, plugin/theme installation, content modification, or backdoor creation. The stored nature means the payload persists and executes for every administrator viewing the application list, increasing the attack’s effectiveness and persistence.
