CVE-2025-58259 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Nokri product developed by scriptsbundle, affecting versions up to 1.6.4. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application without their consent or knowledge. In this case, the vulnerability allows an attacker to perform unauthorized actions on behalf of the user by exploiting the lack of proper CSRF protections in Nokri's web interface. The CVSS 3.1 base score of 7.1 (high severity) indicates that the vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact vector shows no confidentiality loss (C:N), but there is a low integrity impact (I:L) and a high availability impact (A:H), meaning the attacker can cause significant disruption to the availability of the service and modify data to some extent. The vulnerability does not require authentication, making it easier for attackers to exploit if they can lure users into clicking malicious links or visiting crafted web pages. Although no known exploits are currently reported in the wild, the vulnerability's nature and severity suggest that exploitation could lead to service disruption and unauthorized changes to data or settings within Nokri. Nokri is a job board or recruitment-related web application, so the vulnerability could affect organizations using this platform for recruitment or job posting purposes. The absence of published patches at this time increases the urgency for organizations to implement compensating controls.

For European organizations using Nokri, this vulnerability poses a significant risk to the integrity and availability of their recruitment platforms. Attackers could exploit the CSRF flaw to disrupt job posting workflows, modify job listings, or cause denial of service conditions, potentially leading to operational downtime and reputational damage. Since Nokri may handle sensitive candidate and employer data, unauthorized modifications could also undermine trust and compliance with data protection regulations such as GDPR. The high availability impact could result in service outages affecting recruitment processes, which may have downstream effects on hiring timelines and business operations. Additionally, the ease of exploitation without authentication means that attackers could target employees or HR personnel through social engineering tactics, increasing the likelihood of successful attacks. Organizations relying on Nokri for critical recruitment functions should consider this vulnerability a high priority threat.

Given the lack of available patches, European organizations should implement immediate compensating controls to mitigate the risk. These include: 1) Enforce strict Content Security Policy (CSP) headers to restrict the domains from which scripts and requests can be loaded, reducing the risk of malicious cross-site requests. 2) Implement or enhance anti-CSRF tokens in all state-changing requests within Nokri, if customization is possible. 3) Educate users, especially HR and recruitment staff, about the risks of clicking on suspicious links or visiting untrusted websites while authenticated to Nokri. 4) Use web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting Nokri endpoints. 5) Restrict browser sessions to same-site cookies where feasible to limit cross-site request capabilities. 6) Monitor logs for unusual or unauthorized state-changing requests and establish incident response procedures to quickly address potential exploitation. 7) Engage with the vendor or community to track patch releases and apply updates promptly once available.
