WordPress vulnerability analysis and mitigation

The GiveWP – Donation Plugin and Fundraising Platform WordPress plugin before version 2.10.4 contained a stored Cross-Site Scripting (XSS) vulnerability identified as CVE-2021-24315. The vulnerability was discovered in early 2021 and affected the plugin's Background Image field in Stripe Checkout Settings and Logo field in Email settings. The issue was publicly disclosed on April 30, 2021, and subsequently fixed with the release of version 2.10.4 (WPScan).

The vulnerability stems from improper sanitization and escaping of user input in two specific fields: the Background Image field of the Stripe Checkout Setting and the Logo field in Email settings. This security flaw is classified as an authenticated stored XSS vulnerability, with a CVSS score of 5.5 (medium severity). The vulnerability is categorized under CWE-79 and falls into the OWASP Top 10 category A7: Cross-Site Scripting (XSS) (WPScan).

The vulnerability allows authenticated users with administrative privileges to inject malicious JavaScript code into the affected fields. When other users access pages containing the injected code, the malicious script would execute in their browser context, potentially leading to session hijacking, credential theft, or other malicious actions (WPScan).

The vulnerability was patched in GiveWP version 2.10.4, released on April 29th, 2021. Users are strongly advised to update their GiveWP plugin to version 2.10.4 or later to mitigate this security risk (WPScan).
