CVE-2024-6551 is an information disclosure vulnerability classified under CWE-200, impacting the GiveWP Donation Plugin and Fundraising Platform for WordPress in all versions up to and including 3.15.1. The root cause is the plugin's use of the Symfony PHP framework with display_errors enabled in test files, which inadvertently exposes the full filesystem path of the web application to unauthenticated remote attackers. This full path disclosure occurs because error messages generated by Symfony are displayed publicly, revealing directory structures that are typically hidden in production environments. Although the disclosed information does not directly allow unauthorized access or code execution, it provides valuable reconnaissance data that can facilitate more targeted attacks, such as local file inclusion, path traversal, or privilege escalation, especially if combined with other vulnerabilities. The vulnerability requires no authentication or user interaction, making it accessible to any remote attacker scanning for such exposures. The CVSS v3.1 base score is 5.3 (medium severity), reflecting the limited impact on confidentiality and integrity without direct availability impact. No known exploits have been reported, and no official patches have been released at the time of this analysis. The vulnerability highlights the importance of disabling debug or error display features in production environments and properly securing test files within WordPress plugins.

The primary impact of CVE-2024-6551 is the exposure of the full filesystem path of the web application hosting the GiveWP plugin. While this information disclosure does not directly compromise confidentiality or integrity, it significantly aids attackers in mapping the server environment, which can be leveraged to identify further vulnerabilities or misconfigurations. For organizations running GiveWP on WordPress, especially those handling sensitive donation and fundraising data, this reconnaissance can increase the risk of subsequent attacks such as remote code execution, local file inclusion, or privilege escalation if other vulnerabilities exist. The vulnerability affects all unauthenticated users, increasing the attack surface. Although no direct damage occurs from this vulnerability alone, the indirect risk to data confidentiality and system integrity is elevated. Organizations with high-value fundraising platforms or those in regulated sectors may face reputational damage or compliance issues if chained attacks exploit this information leak. The absence of known exploits reduces immediate risk, but the widespread use of GiveWP in nonprofit and charitable organizations worldwide means the potential impact is significant if combined with other flaws.

To mitigate CVE-2024-6551, organizations should immediately verify and disable the display_errors directive in PHP configurations for production environments to prevent error messages from being publicly exposed. Specifically, ensure that the GiveWP plugin’s test files and Symfony framework configurations do not enable error display. Administrators should remove or restrict access to any test or development files within the plugin directory. Employ web application firewalls (WAFs) to detect and block attempts to access error-disclosing endpoints. Monitor web server logs for suspicious requests targeting error pages or test files. Keep the GiveWP plugin updated and subscribe to vendor advisories for forthcoming patches addressing this vulnerability. Conduct regular security audits and vulnerability scans to detect similar information disclosure issues. Additionally, implement least privilege principles and network segmentation to limit the impact of any subsequent attacks leveraging this information. If possible, restrict public access to plugin directories that are not required for normal operation.
