{"id":"BIT-openbao-2026-115359","summary":"OpenBao before 2.6.4 and 2.7.0 before 2.7.1 Role-Based Rate Limit Quota Bypass via Request Parsing","details":"OpenBao before 2.6.4 and 2.7.x before 2.7.1 contains a flaw in its rate limit quota subsystem where role resolution fails for requests with form-encoded bodies or forwarded certificates, so quota rules scoped to backend-specific roles are not enforced. Valid callers can repeatedly issue tokens without consuming the configured role-based rate limit budget.","aliases":["CVE-2026-115359","GHSA-5v22-543h-wg96"],"modified":"2026-10-29T10:55:46.619251294Z","published":"2026-10-29T08:54:36.923Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:openbao:openbao:*:*:*:*:*:go:*:*"]},"references":[{"type":"WEB","url":"https://github.com/openbao/openbao/security/advisories/GHSA-5v22-543h-wg96"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115359"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openbao-before-2.6.4-and-2.7.0-before-2.7.1-role-based-rate-limit-quota-bypass-via-request-parsing"}],"affected":[{"package":{"name":"openbao","ecosystem":"Bitnami","purl":"pkg:bitnami/openbao"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.6.4"},{"introduced":"2.7.0"},{"fixed":"2.7.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/openbao/BIT-openbao-2026-115359.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.2"}
