XSS Payload Test Suite for Hive Frontends ``` ⚠️ FOR AUTHORIZED TESTING ONLY Do not use against systems without explicit written permission. Report ID: AUDIT-20260322 Auditor: louis88 ``` > **Purpose:** Post each payload as a Hive blockchain post body to test sanitization > across condenser and other Hive frontends. All payloads use `alert(1)` or > `alert(document.domain)` as a benign proof-of-concept indicator. > > **How to use:** Each section contains payloads wrapped in markdown code fences > for reference, followed by the raw payload to copy. Test each payload as: > 1. A standalone post body > 2. Wrapped in `...` tags (triggers the raw HTML path in MarkdownViewer) > 3. Inside a markdown paragraph mixed with normal text > 4.

[Payload Chaining & Multi-Stage](#29-payload-chaining--multi-stage) --- ## 1. Standard Vectors Classic payloads that every sanitizer should catch. If any of these fire, the sanitizer is fundamentally broken. ``` XSS-STD-001 ``` ``` XSS-STD-002 ``` ``` XSS-STD-003 ``` ``` XSS-STD-004 ``` ``` XSS-STD-005 ``` ``` XSS-STD-006 — Script with CDATA (XHTML context) ``` ``` XSS-STD-007 — Closing existing tag context ``` ``` XSS-STD-008 — Closing textarea context ``` ``` XSS-STD-009 — Closing noscript context ``` ``` XSS-STD-010 — Line breaks in tag ``` alert(1) --- ## 2. HTML Tag Event Handlers — Exhaustive Comprehensive list of every HTML event handler attribute. Many sanitizers only block `onerror` and `onload` but miss obscure handlers. ### 2.1 Mouse Events ``` XSS-EVT-001 ```
