In `telemetry/telemetry.go`, `clusterFingerprint()` (line 320) calls both `anycableFileConfig(c.ConfigFilePath)` (line 333), which reads the full TOML config file contents, and `anycableCLIArgs()` (line 402), which reads `os.Args[1:]` verbatim—including any `--secret=...`, `--jwt_secret=...`, `--http_rpc_secret=...` arguments. Both raw values are passed to `generateDigest()` (line 373), meaning the actual secret strings flow through the code path and are included in telemetry data sent to the third-party server. Since the hardcoded `authToken = \"secret\"` is public, any attacker who can perform DNS hijacking or is positioned on the network path can intercept and read the telemetry payload containing operator credentials.\n\n### PoC\n1. Read `telemetry/config.go` in the public repo to find `authToken = \"secret\"`.\n2. Set up a DNS spoof for `telemetry.anycable.io` pointing to an attacker-controlled server.\n3. Start anycable-go with `--secret=my-production-secret`.\n4. The server sends a POST to the attacker's endpoint with the telemetry JSON payload. The `clusterFingerprint` field contains data derived from raw `os.Args` including `--secret=my-production-secret`.\n\n### Impact\nIn MITM/DNS-hijack scenarios, production secrets (JWT secrets, broadcast keys, RPC auth) are exposed to third parties. The hardcoded `authToken = \"secret\"` provides no protection since it is known to anyone reading the open-source code.\n\n### Fix\n1. Remove the hardcoded `authToken` from source; generate or require operator configuration at build time or deployment time. 2. Remove `anycableCLIArgs()` from the fingerprint computation, or sanitize it to exclude values of secret-bearing flags before hashing. 3. Add a documented opt-out mechanism for telemetry.","state":0,"publishedAt":"2026-09-18T17:17:29+00:00","modifiedAt":"2026-09-28T17:11:11.8513598+00:00","affected":[{"ecosystem":"Go","name":"github.com/anycable/anycable","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.6.15"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/anycable/anycable/security/advisories/GHSA-w72w-9qmj-c9qm","https://github.com/anycable/anycable/commit/201c67e99e463ed63bd6b345562f4c458385fcee","https://github.com/anycable/anycable","https://github.com/anycable/anycable/releases/tag/v1.6.15"],"sourceUrl":"https://github.com/advisories/GHSA-w72w-9qmj-c9qm","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-w72w-9qmj-c9qm","identifiers":["GHSA-w72w-9qmj-c9qm","CVE-2026-63406","GO-2026-6529"]},"retained":false,"historicalAffected":[]},{"revision":"37bf2afe40b74eb0bae1a1756dcc8472","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6529","aliases":["CVE-2026-63406","GHSA-w72w-9qmj-c9qm"],"title":"AnyCable: Telemetry Subsystem Contains Hardcoded Authentication Token and Transmits CLI Arguments Including Secrets in github.com/anycable/anycable-go","description":"AnyCable: Telemetry Subsystem Contains Hardcoded Authentication Token and Transmits CLI Arguments Including Secrets in github.com/anycable/anycable-go.\n\nNOTE: The source advisory for this report contains additional versions that could not be automatically mapped to standard Go module versions.\n\n(If this is causing false-positive reports from vulnerability scanners, please suggest an edit to the report.)\n\nThe additional affected modules and versions are: github.com/anycable/anycable-go before v1.6.15.","state":0,"publishedAt":"2026-09-28T16:43:40+00:00","modifiedAt":"2026-09-28T17:00:21.6581905+00:00","affected":[{"ecosystem":"Go","name":"github.com/anycable/anycable-go","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/anycable/anycable/security/advisories/GHSA-w72w-9qmj-c9qm","https://github.com/anycable/anycable/commit/201c67e99e463ed63bd6b345562f4c458385fcee","https://github.com/anycable/anycable/releases/tag/v1.6.15"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6529","license":"OSV · upstream source license applies","key":"osv:GO-2026-6529","identifiers":["GO-2026-6529","CVE-2026-63406","GHSA-w72w-9qmj-c9qm"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
