## Summary Four stored XSS issues were confirmed end-to-end on OPNsense after excluding already published GitHub Security Advisories. | ID | Finding | Source actor | Victim page | Status | Practicality | |---|---|---|---|---|---| | XSS-1 | Trust Revocation CRL Description stored XSS | Authenticated user with / | | Confirmed | Delegated WebGUI privilege, not required | | XSS-2 | Firewall rule Description stored XSS in Diagnostics Firewall Live View | Authenticated user with / , plus a logged matching packet | | Confirmed | Delegated WebGUI privilege, not required | | XSS-3 | Dashboard Announcements RSS feed stored XSS | Controlled or compromised trusted RSS/feed source | Dashboard Announcements widget | Confirmed technical sink | Requires control of the trusted announcements feed path | | XSS-4 | Suricata rule metadata stored XSS | Controlled or compromised IDS ruleset source | rule details | Confirmed technical sink | Requires control of a trusted or enabled ruleset source | The first two findings are normal WebGUI stored-config XSS issues reachable by non-root, non- delegated users. OPNsense supports fine-grained privileges through per-user/per-group entries, so a user can hold or without being a full administrator. The last two findings are cross-plane stored XSS issues: external content is fetched, parsed, cached, and later rendered by the WebGUI. They are technically confirmed but have different vendor-actionability because exploitation depends on control of trusted external content. ## Root Cause The common root cause is not a single field type. The recurring pattern is: 1. A text value is stored in configuration, runtime state, feed data, rule metadata, or log-derived state. 2. The value is later considered trusted because it came from an internal API or cached backend state. 3. A WebGUI page decodes or injects the value into an HTML/DOM context. 4. The final rendering step uses raw , template literal HTML, decoded entity data, or an unsanitized table formatte
