CVE-2025-12643 is a stored cross-site scripting vulnerability in the Saphali LiqPay for donate WordPress plugin, affecting all versions up to and including 1.0.2. The issue stems from improper neutralization of input during web page generation, specifically insufficient sanitization and output escaping of attributes passed via the 'saphali_liqpay' shortcode. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of users visiting the compromised pages.

Successful exploitation allows an authenticated user with contributor-level or higher access to inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who visit the affected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not affect availability and requires authenticated access, limiting the attack surface.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Saphali LiqPay for donate plugin if feasible. Monitor official channels for updates or patches addressing this vulnerability.
