CVE-2025-47468 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Hash Form product developed by hashthemes, affecting versions up to 1.2.8. 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, causing the application to perform unwanted actions on behalf of the user without their consent. In this case, the vulnerability allows an attacker to potentially induce users to execute unintended state-changing requests via the Hash Form interface. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires no privileges, but does require user interaction (e.g., clicking a malicious link). The impact is limited to integrity loss (I:L) without affecting confidentiality or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-352, which is a well-known web security issue related to insufficient request validation to prevent CSRF attacks.

For European organizations using the Hash Form plugin or product, this vulnerability poses a risk of unauthorized modification of data or settings through CSRF attacks. Although the impact is limited to integrity and does not affect confidentiality or availability, attackers could manipulate form submissions or configurations, potentially leading to data corruption, unauthorized changes in application behavior, or disruption of business processes relying on the form. This could undermine trust in web applications and lead to compliance issues, especially under regulations like GDPR if personal data integrity is compromised. The requirement for user interaction reduces the risk somewhat but does not eliminate it, as phishing or social engineering could be used to trick users into triggering the exploit. The absence of known exploits in the wild suggests the threat is currently low but could increase once exploit code becomes available.

European organizations should implement specific mitigations beyond generic advice: 1) Immediately review and apply any forthcoming patches or updates from hashthemes for Hash Form. 2) Implement anti-CSRF tokens in all forms and verify them server-side to ensure requests originate from legitimate sources. 3) Employ SameSite cookie attributes (preferably 'Strict' or 'Lax') to reduce the risk of CSRF via cross-site requests. 4) Educate users about the risks of clicking unknown or suspicious links, especially when authenticated to sensitive web applications. 5) Monitor web application logs for unusual or unexpected form submissions that could indicate attempted exploitation. 6) If immediate patching is not possible, consider disabling or restricting the use of the vulnerable Hash Form functionality until a fix is available. 7) Use web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting the affected endpoints.
