CVE-2025-53269 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the imw3 My Wp Brand plugin, affecting versions up to 1.1.3. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request to a web application where the user is currently authenticated. This can result in unauthorized actions being performed on behalf of the user without their consent. In this case, the vulnerability allows an attacker to craft malicious requests that, when executed by a logged-in user, could alter settings or perform actions within the My Wp Brand plugin environment. The CVSS 3.1 base score is 4.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality impact (C:N), low integrity impact (I:L), and no availability impact (A:N). This means the attack can be launched remotely without authentication but requires the user to interact with a malicious link or site. The integrity impact is low, suggesting that the unauthorized actions may cause limited modification or disruption of data or settings. No known exploits are reported in the wild yet, and no patches are currently linked, indicating that mitigation may require manual intervention or vendor updates. The vulnerability is categorized under CWE-352, which is a common web security weakness related to CSRF attacks. Given the plugin's integration with WordPress environments, the vulnerability could be leveraged to manipulate branding or configuration settings, potentially leading to defacement, misinformation, or degraded trust in the affected websites.

For European organizations using the imw3 My Wp Brand plugin, this vulnerability poses a risk primarily to the integrity of their web presence. An attacker exploiting this CSRF flaw could cause unauthorized changes to website branding or configuration, potentially leading to misinformation, reputational damage, or user confusion. While the confidentiality and availability impacts are minimal, the integrity compromise could affect customer trust and brand perception, especially for businesses relying heavily on their online identity. Public sector websites, e-commerce platforms, and service providers in Europe that use this plugin are at risk of targeted attacks aiming to disrupt user experience or spread misinformation. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to trick employees or customers into triggering the malicious requests. The medium severity score reflects a moderate threat level, but the actual impact depends on the criticality of the affected website and the sensitivity of the altered content. Organizations with strict regulatory compliance requirements (e.g., GDPR) should consider the potential indirect effects of such integrity breaches on data protection and user trust.

To mitigate this CSRF vulnerability, European organizations should: 1) Immediately review and restrict the use of the imw3 My Wp Brand plugin, especially on critical or public-facing websites. 2) Implement strict Content Security Policies (CSP) and SameSite cookie attributes to reduce the risk of CSRF attacks by limiting cross-origin requests. 3) Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting WordPress plugins. 4) Educate users and administrators about the risks of clicking on unsolicited links or visiting untrusted websites to reduce the likelihood of user interaction exploitation. 5) Monitor web server and application logs for unusual POST requests or configuration changes that could indicate attempted exploitation. 6) Coordinate with the plugin vendor or community to obtain or develop patches or updates that add proper CSRF tokens and validation mechanisms. 7) Consider disabling or replacing the vulnerable plugin with alternatives that follow secure coding practices. 8) Conduct regular security assessments and penetration tests focusing on web application vulnerabilities including CSRF to proactively identify and remediate weaknesses.
