CVE-2025-53249 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the hakeemnala Build App Online product, affecting versions up to 1.0.23. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. This specific vulnerability does not impact confidentiality or integrity directly but affects availability, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). The attack vector is network-based with low attack complexity and no privileges required, but user interaction is necessary (the victim must be tricked into clicking a malicious link or visiting a crafted webpage). The vulnerability allows an attacker to cause denial of service or disrupt the normal functioning of the Build App Online platform by forcing the victim’s browser to perform unwanted actions. Since no patch links are provided and no known exploits are reported in the wild, the vulnerability appears to be newly disclosed and unpatched at the time of publication. The CWE-352 classification confirms the nature of the vulnerability as CSRF. The product, Build App Online by hakeemnala, is a web-based application development platform, which likely manages user projects and data online, making availability disruptions potentially impactful for users relying on the service for development workflows.

For European organizations using hakeemnala Build App Online, this vulnerability could lead to service disruptions and denial of availability of critical development tools hosted on this platform. While the vulnerability does not directly compromise data confidentiality or integrity, the forced execution of unwanted actions could interrupt development processes, cause loss of unsaved work, or trigger unintended operations that degrade service reliability. Organizations relying on this platform for internal or client-facing application development may experience productivity losses and operational delays. Additionally, if the platform is integrated with other internal systems or CI/CD pipelines, the disruption could cascade, affecting broader IT operations. Given the network attack vector and lack of required privileges, attackers could exploit this vulnerability remotely, increasing the risk profile for organizations with users who access the platform via web browsers without adequate CSRF protections.

To mitigate this CSRF vulnerability, organizations should implement strict anti-CSRF tokens in all state-changing requests within the Build App Online platform. This involves ensuring that every form or state-changing HTTP request includes a unique, unpredictable token that the server validates before processing the request. Additionally, enforcing SameSite cookie attributes (preferably 'Strict' or 'Lax') can reduce the risk of CSRF by limiting cookie transmission in cross-site contexts. Organizations should also educate users to avoid clicking on suspicious links or visiting untrusted websites while authenticated to the platform. Network-level mitigations such as Web Application Firewalls (WAFs) can be configured to detect and block suspicious cross-site requests. Monitoring and logging unusual activity on the platform can help detect attempted exploitation. Since no patches are currently available, organizations should engage with the vendor for updates and consider temporary workarounds such as session timeouts or multi-factor authentication to reduce the risk window.
