CVE-2025-50050 is a Stored Cross-site Scripting (XSS) vulnerability classified under CWE-79 that affects the 'Jobs for WordPress' plugin developed by BlueGlass Interactive AG. This vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be stored and subsequently executed in the context of users visiting affected web pages. The flaw impacts versions up to 2.7.12 of the plugin. Exploitation requires an attacker with at least low privileges (PR:L) to submit crafted input that is not properly sanitized or encoded before being rendered on the front-end or back-end interfaces. The CVSS v3.1 base score is 6.5 (medium severity), reflecting network attack vector (AV:N), low attack complexity (AC:L), requirement for privileges (PR:L), user interaction (UI:R), and scope change (S:C). The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as malicious scripts can steal session cookies, perform actions on behalf of users, or deface content. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability is particularly relevant for websites using the Jobs for WordPress plugin to manage job listings, which may include corporate career portals or recruitment agencies. Given the nature of stored XSS, the attack surface includes any user or administrator interface that renders user-generated content without proper sanitization, potentially affecting logged-in users and visitors alike.

For European organizations, this vulnerability poses a moderate risk, especially for those relying on WordPress-based career or recruitment sites using the affected plugin. Exploitation could lead to session hijacking, unauthorized actions performed under the context of authenticated users, or defacement of job listings, damaging organizational reputation. Confidential information such as user credentials or personal data could be exposed if attackers inject scripts to capture input or cookies. The scope change in the CVSS vector indicates that the vulnerability can affect components beyond the initially targeted scope, potentially impacting administrative functions. Organizations in sectors with high recruitment activity, such as technology, finance, and manufacturing, may face increased risk due to the strategic importance of their career portals. Additionally, the presence of user interaction as a requirement means phishing or social engineering could facilitate exploitation. While no active exploits are known, the medium severity and ease of exploitation (low complexity) warrant proactive mitigation to prevent potential attacks that could disrupt availability or compromise data integrity.

1. Immediate mitigation should include disabling or restricting access to the Jobs for WordPress plugin until an official patch is released. 2. Implement strict input validation and output encoding on all user-supplied data fields related to job postings and user comments, leveraging WordPress security functions such as esc_html(), esc_attr(), and wp_kses() to sanitize content. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. 4. Limit privileges for users who can submit or edit job listings to trusted personnel only, reducing the risk of malicious input. 5. Monitor web server logs and application logs for suspicious input patterns or unusual user activity indicative of attempted XSS exploitation. 6. Educate administrators and users about the risks of clicking on suspicious links or interacting with untrusted content on the site. 7. Regularly update WordPress core and all plugins to the latest versions once patches addressing this vulnerability become available. 8. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS attack signatures specific to the Jobs for WordPress plugin context.
