CVE-2025-8780 is a stored cross-site scripting vulnerability in the Livemesh SiteOrigin Widgets WordPress plugin, affecting versions up to 3.9.1. The issue occurs due to improper neutralization of input during web page generation, specifically in the Hero Header and Pricing Table widgets. Authenticated attackers with contributor or higher privileges can inject malicious scripts via user-supplied attributes that are not properly sanitized or escaped, leading to script execution in the context of users visiting the injected pages. The vulnerability has a CVSS 3.1 score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), indicating network attack vector, low attack complexity, requiring privileges, no user interaction, scope changed, with low confidentiality and integrity impact and no availability impact.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via vulnerable widgets. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability affects confidentiality and integrity to a limited extent but does not impact availability. There are no known active exploits in the wild.

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 affected widgets (Hero Header and Pricing Table) to prevent exploitation. Monitor for updates from the Livemesh vendor regarding patches or official mitigations.
