SVG <foreignObject> embedded HTML (sandbox bypass)
svg-foreign-object-in-body
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Email HTML body contains an SVG `<foreignObject>` element. `<foreignObject>` lets an SVG embed a whole XHTML payload (iframes, forms, password inputs, scripts) inside a namespace that mail-client sanitizers often fail to recurse into. Legitimate email never uses `<foreignObject>` — logos and data visualizations use pre-rendered images or plain SVG without embedded HTML. The presence of `<foreignObject>` anywhere in an email body is exclusively a sandbox-escape / sanitizer-bypass attempt. Weighted at +5, matching script-in-body, iframe-in-body, and inline-event-handler-in-body — all client-side-execution vectors.
False-positive guard
Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.
About the scoring engine
Gorganizer's scoring engine emits 2,143+ signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.
Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
