CVE-2024-0966 is a stored cross-site scripting vulnerability in the 3uu Shariff Wrapper WordPress plugin affecting all versions up to 4.6.9. The issue is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'info_text' attribute in the plugin's 'shariff' shortcode. Authenticated users with contributor-level or higher privileges can exploit this to inject malicious scripts that execute in the context of other users viewing the page, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity without availability impact.

An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages via the 'shariff' shortcode's 'info_text' attribute. These scripts execute when other users access the injected page and click the information icon, potentially leading to partial confidentiality and integrity compromise. There is no impact on availability. The vulnerability could be leveraged to steal session tokens, perform actions on behalf of other users, or disclose sensitive information within the affected site context.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently provided. Until a patch is available, restrict contributor-level permissions to trusted users only and consider disabling or removing the Shariff Wrapper plugin if feasible. Monitor vendor channels for updates and apply official patches promptly once released.
