CVE-2026-16573: CWE-79 Cross-Site Scripting (XSS) in Bit Form
The Bit Form WordPress plugin before 3.2.0 does not sanitize an uploaded signature image before storing it, allowing unauthenticated attackers to upload a crafted SVG file containing JavaScript that executes when the file is viewed, leading to Stored Cross-Site Scripting.
AI Analysis
Technical Summary
The Bit Form WordPress plugin prior to version 3.2.0 fails to sanitize uploaded signature images, specifically SVG files, allowing unauthenticated attackers to upload SVG files containing malicious JavaScript. This results in stored cross-site scripting (CWE-79) that executes when the SVG file is viewed, potentially compromising site visitors or administrators who view the infected content.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in the context of the affected site when the malicious SVG image is viewed. This can lead to session hijacking, defacement, or other client-side attacks depending on the victim's privileges and browser context.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict or disable SVG uploads and implement manual validation or sanitization of uploaded images to prevent malicious scripts from being stored and executed.
