CVE-2025-52769 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the flexostudio flexo-social-gallery product, affecting versions up to 1.0006. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application in which the user is currently authenticated, thereby performing unwanted actions without the user's consent. In this case, the flexo-social-gallery plugin lacks adequate CSRF protections, allowing attackers to craft malicious requests that, when executed by an authenticated user, can alter application state or perform actions on their behalf. 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 attacker can exploit the vulnerability remotely without authentication but requires the user to interact (e.g., clicking a link). The integrity impact suggests that the attacker can modify or manipulate data or settings within the application, potentially leading to unauthorized changes or defacement. No known exploits are currently in the wild, and no patches have been linked yet, indicating that mitigation may rely on configuration changes or upcoming vendor fixes. The vulnerability is classified under CWE-352, a common web application security weakness related to insufficient request validation against CSRF attacks.

For European organizations using flexostudio's flexo-social-gallery plugin—commonly employed to display social media content in galleries on websites—this vulnerability could allow attackers to perform unauthorized actions by leveraging authenticated users' sessions. Potential impacts include unauthorized modification of gallery content, configuration changes, or other actions permitted by the plugin's interface. While the confidentiality impact is none, the integrity of displayed content and user trust could be compromised, leading to reputational damage. Since the attack requires user interaction, phishing or social engineering campaigns could be used to trick users into executing malicious requests. This risk is particularly relevant for organizations with public-facing websites that integrate this plugin, including media companies, marketing agencies, and e-commerce platforms. The absence of known exploits reduces immediate risk, but the medium severity and ease of exploitation without authentication mean organizations should proactively address the issue to prevent future exploitation.

To mitigate this CSRF vulnerability, European organizations should implement the following specific measures: 1) Immediately audit all web applications using flexo-social-gallery to identify affected versions. 2) Apply any vendor patches or updates as soon as they become available. 3) If patches are not yet released, implement web application firewall (WAF) rules to detect and block suspicious CSRF-like requests targeting the plugin endpoints. 4) Enforce strict Content Security Policy (CSP) headers to reduce the risk of malicious script execution. 5) Educate users about phishing and social engineering tactics that could lead to CSRF exploitation, emphasizing cautious behavior with unsolicited links. 6) Where possible, implement additional CSRF tokens or anti-CSRF mechanisms at the application level to validate legitimate requests. 7) Monitor web server and application logs for unusual or unauthorized requests that could indicate attempted exploitation. 8) Consider isolating or disabling the flexo-social-gallery plugin temporarily if it is not critical to operations until a secure version is available.
