CVE-2026-75626: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in smicallef spiderfoot
SpiderFoot fails to HTML-escape correlation titles built from external scan data sources including server banners and metadata. Attackers can inject malicious HTML elements with event handlers into correlation results that execute scripts in the operator's browser when the correlations view is opened, potentially stealing API keys.
AI Analysis
Technical Summary
CVE-2026-75626 is a critical cross-site scripting vulnerability in SpiderFoot (smicallef) affecting versions up to 4.0. The issue arises because SpiderFoot fails to properly HTML-escape correlation titles generated from external data sources such as server banners and metadata. An attacker can exploit this by injecting malicious HTML elements containing event handlers into these correlation results. When the operator opens the correlations view, the injected scripts execute in their browser context, potentially compromising API keys and other sensitive data.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary scripts in the context of the operator's browser without privileges or user interaction beyond viewing the correlations page. This can lead to theft of API keys and compromise of sensitive information managed by SpiderFoot.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid opening untrusted correlation results or external scan data within SpiderFoot. Monitor vendor channels for updates regarding an official fix.
