CVE-2025-9057: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Mikado Themes Biagiotti Core
The Biagiotti Core plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcodes in versions up to, and including, 2.1.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
The Biagiotti Core plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated users with contributor-level or higher permissions can exploit this by injecting arbitrary scripts via shortcode attributes that are not properly sanitized or escaped. This results in script execution in the context of users visiting the affected pages. The vulnerability affects all versions up to 2.1.3. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges, no user interaction, with scope changed and low impact on confidentiality and integrity, and no impact on availability.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via shortcode attributes. These scripts execute in the browsers of users who view the infected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not affect availability and has low impact on confidentiality and integrity according to the CVSS score. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level permissions to trusted users only and consider removing or disabling the Biagiotti Core plugin if possible. Monitor for plugin updates from Mikado Themes that address this vulnerability.
