CVE-2026-75626
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
