The parser recursed once for each nested array level without enforcing a depth limit. The fix adds a configurable Redis reply depth limit with default value 128 and rejects replies exceeding that limit. \n\nAffected Scenarios:\nApplications using bRPC as a Redis client with ChannelOptions.protocol=\"redis\" and receiving replies from an untrusted or faulty Redis server peer.\n\nHow to Fix:\n1. Upgrade Apache bRPC to 1.18.0.\n2. Apply the patch from PR  https://github.com/apache/brpc/pull/3344 .\n\nNote:\nAfter applying the fix, Redis replies with array nesting deeper than redis_max_reply_depth are rejected.","score":7.5,"severity":"high","published":"2026-10-21T11:32:19.591Z","modified":"2026-10-30T13:46:51.555Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Apache Software Foundation","name":"Apache bRPC","platforms":[],"versions":[{"version":"0","status":"affected","lessThan":"1.18.0","versionType":"semver"}],"defaultStatus":"unaffected","packageURL":"pkg:github/apache/brpc","cpes":[],"source":"apache","url":"https://www.cve.org/CVERecord?id=CVE-2026-54426"}],"remediation":[],"references":["https://lists.apache.org/thread/2pf15ojj0vr7rtx95677kgtl1mx3gdgb"],"sources":[{"name":"CVE","id":"CVE-2026-54426","modified":"2026-10-30T13:46:51.555Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-54426"}],"assessments":[{"source":"CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5}],"sourceAffected":[],"observedAt":"2026-10-30T15:33:30.064Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T09:10:30.844Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-30T15:50:36.796Z","attemptedAt":"2026-10-30T15:50:36.796Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-30T15:50:40.512Z","attemptedAt":"2026-10-30T15:50:40.512Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-30T15:50:38.993Z","attemptedAt":"2026-10-30T15:50:38.993Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-30T15:50:35.066Z","attemptedAt":"2026-10-30T15:50:35.066Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-54426","url":"https://www.first.org/epss/","probability":0.00159,"percentile":0.04986,"date":"2026-10-30","checkedAt":"2026-10-30T15:50:35.066Z"},{"source":"NVD","id":"CVE-2026-54426","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54426","modified":"2026-10-30T14:17:06.137","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T15:50:36.796Z"},{"source":"ENISA EUVD","id":"EUVD-2026-107170","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-107170","modified":"Oct 30, 2026, 1:46:51 PM","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T15:50:38.993Z"},{"source":"GitHub Advisory Database","id":"GHSA-m7v5-m3p2-6w26","url":"https://github.com/advisories/GHSA-m7v5-m3p2-6w26","modified":"2026-10-30T15:35:16Z","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T15:50:40.512Z"}],"aiSummary":null}
