A malformed STUN packet containing a short or empty XOR-MAPPED-ADDRESS attribute triggers a runtime slice-bounds panic during parsing, terminating the entire Go process.\n\n## TL;DR\nUnauthenticated malformed STUN packets can trigger a runtime panic in Pion STUN before 3.1.3, causing a denial of service.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-20\n- **Attack Vector**: Network\n- **CVSS v3.1 Score**: 5.3\n- **Impact**: Denial of Service\n- **Exploit Status**: poc\n- **CISA KEV Status**: No\n\n## Affected Systems\n\n- Pion STUN (Go module github.com/pion/stun)\n- Pion TURN (transitive dependency)\n- Pion WebRTC (transitive dependency)\n- Applications acting as WebRTC signaling or media servers using the affected libraries\n- **stun**: < 3.1.3 (Fixed in: `3.1.3`)\n\n## Mitigation\n\n- Upgrade github.com/pion/stun to version 3.1.3 or later\n- Filter out malformed STUN packets at the network layer using an IDS/IPS or firewall rule\n- Audit downstream imports (such as pion/turn or pion/webrtc) to ensure they resolve to the fixed version of pion/stun\n\n**Remediation Steps:**\n1. Open the go.mod file of the affected project\n2. Run 'go get github.com/pion/stun/v3@v3.1.3'\n3. Run 'go mod tidy' to update downstream dependencies\n4. Recompile and redeploy the application\n\n## References\n\n- [GitHub Security Advisory GHSA-34rh-wp3j-6cxc](https://github.com/pion/stun/security/advisories/GHSA-34rh-wp3j-6cxc)\n- [Pion STUN Pull Request 278](https://github.com/pion/stun/pull/278)\n- [Fix Commit fa9f074a](https://github.com/pion/stun/commit/fa9f074a33a8059c76c960b1fbee39f308002423)\n- [Pion STUN v3.1.3 Release](https://github.com/pion/stun/releases/tag/v3.1.3)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-54909) - Automated Vulnerability Intelligence*", "url": "https://gist.github.com/alon710/402cd5e451c20f1dfc47c5b8f0cf1ddb"}, {"timestamp": "2026-08-03T17:28:49.547Z", "date_only": false, "value": "2026-08-03T17:28:49.547530Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-54909", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-08-03T17:28:49.547Z", "date_only": false, "value": "2026-08-03T17:28:49.547530Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-54909", "record": "FKIE_CVE-2026-54909", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-08-03T17:30:22.558Z", "date_only": false, "value": "2026-08-03T17:30:22.558Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-54909", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-08-03T17:30:22.558Z", "date_only": false, "value": "2026-08-03T17:30:22.558Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-54909", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-17T09:45:55Z", "date_only": false, "value": "2026-10-17T09:45:55Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-54909", "record": "UBUNTU-CVE-2026-54909", "field": "modified"}, {"timestamp": "2026-10-23T23:10:00.157Z", "date_only": false, "value": "2026-10-23T23:10:00.157", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-54909", "record": "FKIE_CVE-2026-54909", "field": "lastModified"}], "metrics": {"as_of": "2026-10-30T10:38:12.635Z", "anchors": {"origin": {"timestamp": "2026-07-31T22:03:42Z", "date_only": false, "value": "2026-07-31T22:03:42Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-34RH-WP3J-6CXC", "record": "GHSA-34RH-WP3J-6CXC", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-07-31T22:03:42Z", "date_only": false, "value": "2026-07-31T22:03:42Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-34RH-WP3J-6CXC", "record": "GHSA-34RH-WP3J-6CXC", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 7821270.635613, "hours": 2172.5751765591667, "days": 90.52396568996528, "min_seconds": 7821270.635613, "max_seconds": 7821270.635613, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-07-31T22:03:42Z", "date_only": false, "value": "2026-07-31T22:03:42Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-34RH-WP3J-6CXC", "record": "GHSA-34RH-WP3J-6CXC", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-10-30T10:38:12.635Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
