DescriptionCVE.org

The GiveWP - Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'give_form' shortcode in all versions up to, and including, 4.14.4. This is due to insufficient input sanitization and output escaping on the continue_button_title and display_style shortcode attributes, which are passed through sanitize_text_field() but not properly escaped when output in HTML data attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AnalysisAI

Stored Cross-Site Scripting in GiveWP (WordPress donation plugin by StellarWP, versions through 4.14.4) allows authenticated Contributor-level users to inject persistent JavaScript payloads into donation form pages via the give_form shortcode. The flaw arises because the continue_button_title and display_style shortcode attributes are sanitized with sanitize_text_field() - which strips HTML tags but does not encode special characters - and then written unescaped into HTML data attributes, leaving a standard XSS sink unguarded. …

Vulnerability AssessmentAI

Exploitation The attacker must hold at minimum Contributor-level authenticated access to the target WordPress installation; unauthenticated exploitation is not possible given PR:L in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 6.4 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N correctly identifies the key risk dimensions: the attack is network-accessible and low-complexity, but requires Contributor-level authentication (PR:L), which is the primary mitigating factor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation A code-level fix has been committed to the GiveWP plugin trunk via WordPress Plugin SVN changeset 3501918 (https://plugins.trac.wordpress.org/changeset/3501918/); however, the exact released patched version number is not stated in the available data and has not been independently confirmed - administrators should update to the latest available version of GiveWP via the WordPress Plugin Directory and verify the installed version exceeds 4.14.4. … Detailed patch versions, workarounds, and compensating controls in full report.
