CVE-2025-11228 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the GiveWP Donation Plugin and Fundraising Platform for WordPress. The vulnerability arises from the lack of a capability check in the function `registerAssociateFormsWithCampaign`, which is responsible for associating donation forms with fundraising campaigns. Because this function does not verify the privileges of the caller, unauthenticated attackers can invoke it to link any donation form to any campaign arbitrarily. This unauthorized modification can lead to manipulation of donation flows, potentially redirecting funds or confusing donors. The vulnerability affects all versions up to and including 4.10.0. The CVSS v3.1 base score is 5.3, reflecting medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), integrity impact (I:L), and no availability impact (A:N). There are currently no known exploits in the wild, and no patches have been linked yet. The vulnerability was publicly disclosed on October 4, 2025, by Wordfence. The primary risk is unauthorized integrity modification of donation data, which could undermine trust in fundraising campaigns and cause reputational damage to organizations relying on GiveWP for donations.

For European organizations, especially nonprofits and charities using WordPress with the GiveWP plugin, this vulnerability poses a risk of unauthorized manipulation of donation campaigns. Attackers could associate donation forms with incorrect campaigns, potentially diverting funds or causing donor confusion. While the vulnerability does not expose sensitive donor information or disrupt service availability, the integrity compromise could damage organizational reputation and donor trust, which are critical for fundraising success. Given the widespread use of WordPress and the popularity of GiveWP among European nonprofits, the impact could be significant if exploited at scale. Additionally, manipulation of donation campaigns could have regulatory implications under European data protection and financial transparency laws, such as GDPR and anti-fraud regulations. Organizations relying on GiveWP should consider the potential financial and reputational consequences of this vulnerability.

Since no official patch is currently available, European organizations should implement the following mitigations: 1) Restrict access to the vulnerable function by applying custom code or web application firewall (WAF) rules to block unauthenticated requests targeting `registerAssociateFormsWithCampaign`. 2) Monitor logs and audit trails for unusual or unauthorized changes to donation form associations. 3) Temporarily disable or limit the use of the affected functionality if feasible until a patch is released. 4) Ensure WordPress core and all plugins, including GiveWP, are kept up to date once a security update addressing this vulnerability is published. 5) Educate fundraising and IT teams about the risk and signs of exploitation to enable rapid detection and response. 6) Consider implementing multi-factor authentication and role-based access controls for administrative functions related to donation management to reduce risk from other attack vectors. 7) Engage with the GiveWP vendor or community for updates and recommended fixes.
