{"id":"CVE-2025-29923","aliases":["GHSA-92cp-5422-2mw7","GO-2025-3540"],"url":"https://o3.security/vulnerability/CVE-2025-29923","summary":"go-redis allows potential out of order responses when `CLIENT SETINFO` times out during connection establishment","details":"### Impact\n\nThe issue only occurs when the `CLIENT SETINFO` command times out during connection establishment. The following circumstances can cause such a timeout:\n\n1. The client is configured to transmit its identity. This can be disabled via the `DisableIndentity` flag.\n2. There are network connectivity issues\n3. The client was configured with aggressive timeouts\n\nThe impact differs by use case:\n\n* **Sticky connections**: Rather than using a connection from the pool on-demand, the caller can stick with a connection. Then you receive persistent out-of-order responses for the lifetime of the connection.\n* **Pipelines**: All commands in the pipeline receive incorrect responses.\n* **Default connection pool usage without pipelining**: When used with the default [ConnPool](https://github.com/redis/go-redis/blob/8fadbef84a3f4e7573f8b38e5023fd469470a8a4/internal/pool/pool.go#L77) once a connection is returned after use with [ConnPool#Put](https://github.com/redis/go-redis/blob/8fadbef84a3f4e7573f8b38e5023fd469470a8a4/internal/pool/pool.go#L366) the read buffer will be checked and the connection will be marked as bad due to the unread data. This means that at most one out-of-order response before the connection is discarded.\n\n### Patches\nWe prepared a fix in https://github.com/redis/go-redis/pull/3295 and plan to release patch versions soon. Versions 9.7.2, 9.6.3, and 9.5.5 were patched. However, 9.7.2 has been yanked, making 9.7.3 the lowest available 9.7.x version with a patch.\n\n### Workarounds\nYou can prevent the vulnerability by setting the flag `DisableIndentity` (BTW: We also need to fix the spelling.) to `true` when constructing the client instance.\n\n### Credit\n\nAkhass Wasti\nRamin Ghorashi\nAnton Amlinger\nSyed Rahman\nMahesh Venkateswaran\nSergey Zavoloka\nAditya Adarwal\nAbdulla Anam\nAbd-Alhameed\nAlex Vanlint\nGaurav Choudhary\nVedanta Jha\nYll Kelani\nRyan Picard","published":"2025-03-20T18:03:14.933Z","modified":"2026-09-05T03:30:47.455568642Z","cvss":{"score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.00724,"percentile":0.5127,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/redis/go-redis/v9","fixedVersion":"9.7.3"},{"ecosystem":"Go","name":"github.com/redis/go-redis/v9","fixedVersion":"9.6.3"},{"ecosystem":"Go","name":"github.com/redis/go-redis/v9","fixedVersion":"9.5.5"}],"fix":{"url":"https://github.com/redis/go-redis/commit/d236865b0cfa1b752ea4b7da666b1fdcd0acebb6","label":"redis/go-redis@d236865"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/29xxx/CVE-2025-29923.json"},{"type":"ADVISORY","url":"https://github.com/redis/go-redis/security/advisories/GHSA-92cp-5422-2mw7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-29923"},{"type":"FIX","url":"https://github.com/redis/go-redis/commit/d236865b0cfa1b752ea4b7da666b1fdcd0acebb6"},{"type":"FIX","url":"https://github.com/redis/go-redis/pull/3295"},{"type":"PACKAGE","url":"https://github.com/redis/go-redis"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-05T03:30:47.455568642Z"}}
