CVE-2025-53263 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'Address Autocomplete via Google for Gravity Forms' developed by PluginsCafe. This vulnerability affects all versions up to and including 1.3.4. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged request to a web application in which they are currently authenticated, potentially causing unintended actions without the user's consent. In this case, the vulnerability resides in the plugin's handling of form submissions or related actions that integrate Google Address Autocomplete functionality within Gravity Forms, a popular WordPress form builder. The CVSS 3.1 base score of 5.4 indicates a medium severity level, with the vector string AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L meaning the attack can be launched remotely over the network without privileges, requires low attack complexity, no privileges, but does require user interaction (the victim must be tricked into clicking a malicious link or visiting a crafted webpage). The impact affects integrity and availability but not confidentiality, implying that attackers could manipulate form data or disrupt form functionality but not directly access sensitive data. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that mitigation may rely on plugin updates or manual hardening. The vulnerability is categorized under CWE-352, which is a well-known web security weakness related to insufficient anti-CSRF protections such as missing or ineffective CSRF tokens or validation mechanisms.

For European organizations using WordPress websites with Gravity Forms and the vulnerable PluginsCafe Address Autocomplete plugin, this vulnerability could lead to unauthorized manipulation of form data or disruption of form-based workflows. This can affect customer-facing forms, lead generation, or internal data collection processes, potentially causing data integrity issues or denial of service on form submissions. While confidentiality is not directly impacted, the integrity and availability concerns could undermine trust in web services and cause operational disruptions. Organizations handling sensitive or regulated data through these forms may face compliance risks if form data is altered or lost. Additionally, attackers could leverage this vulnerability as part of a broader attack chain, potentially escalating impact. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability, which is a common attack vector in Europe. The medium severity suggests that while the threat is not critical, it is significant enough to warrant timely remediation to prevent exploitation.

European organizations should prioritize updating the PluginsCafe Address Autocomplete via Google for Gravity Forms plugin as soon as a patch is released by the vendor. Until then, practical mitigations include implementing web application firewall (WAF) rules to detect and block suspicious CSRF attempts targeting Gravity Forms endpoints. Administrators should verify that Gravity Forms and related plugins enforce anti-CSRF tokens on all form submissions and consider adding custom nonce or token validation if the plugin lacks it. Educating users about phishing risks and avoiding clicking on suspicious links can reduce the likelihood of successful CSRF attacks. Additionally, restricting form submission methods to POST only and validating the HTTP Referer header can provide additional layers of defense. Monitoring web server logs for unusual form submission patterns can help detect exploitation attempts early. Finally, organizations should review their WordPress security posture, including limiting plugin usage to trusted and actively maintained components, and applying the principle of least privilege to WordPress user roles to minimize potential damage.
