Summary
OpenBao is a secrets management system. Prior to version 2.4.2, the audit log did not properly redact fields when subsystems sent []byte parameters instead of strings. This includes sys/raw with encoding=base64 and Transit signing with Ed25519 keys, causing data exposure in audit logs. The issue is fixed in 2.4.2.
Risk Assessment
Sensitive data such as secrets or public keys may leak into audit logs, posing a risk of disclosure. This could lead to confidentiality and security breaches.
Recommendation
Update OpenBao to version 2.4.2 or later. Review existing audit logs for potential data leaks.
Other vulnerabilities in OpenBao
See all- CVE-2026-42186High
OpenBao is an identity-based secrets management system. Prior to version 2.5.3, when the initial namespace deletion fails, subsequent retries do not properly remove all data before marking the namespace as deleted.
- CVE-2026-63132Critical
OpenBao is an open source identity-based secrets management system. Prior to 2.6.0, OpenBao's handleLogicalRecovery path in http/logical.go compared the highly privileged recovery token with ordinary string equality. A remote unauthenticated attacker able to make repeated recovery mode requests and measure response timing could infer the recovery token. The recovered token could then authorize recovery mode operations that read or modify OpenBao data. This issue is fixed in version 2.6.0.
- CVE-2026-33757Critical
OpenBao prior to version 2.5.2 does not prompt for user confirmation when logging in via JWT/OIDC with a role set to `callback_mode=direct`. This allows an attacker to perform remote phishing by having the victim visit a URL and automatically log into the attacker's session.
- CVE-2026-115369Low
OpenBao from 2.5.0 before 2.6.2 fails to enforce the PKI role allowed_ip_sans_cidr restriction on IP SANs taken from a CSR when use_csr_sans is enabled. Authenticated callers with sign permission can submit a CSR with an out-of-range IP SAN to pki/sign/<role> and obtain CA-signed certificates for unauthorized IPs.
- CVE-2026-115366Low
OpenBao from 2.3.0 before 2.6.3 contains an improper authorization vulnerability that allows privileged child-namespace tokens to modify plugin registrations because /v1/sys/plugins/catalog/* is not restricted to the root namespace. Attackers can remove existing registrations, create invalid ones, or register installed plugins through a child namespace's sys/ mount, causing denial of service.
- CVE-2026-115365Medium
An incorrect authorization vulnerability in OpenBao's ACL policy cache allows tokens to reference policies from arbitrary namespaces using specially crafted policy names. An attacker holding such tokens can gain capabilities of cached policies in other namespaces, including the root namespace, and act across namespace boundaries.
- CVE-2026-115364Low
OpenBao before 2.6.3 contains a missing authorization check that allows attackers to stop Agent and Proxy services by omitting the X-Vault-Header. When require_request_header is enabled, attackers can send requests via server-side request forgery to /agent/v1/quit or /proxy/v1/quit to shut down these services.
- CVE-2026-115363Low
OpenBao 2.2.0 before 2.6.4 and 2.7.0 before 2.7.1 contains an information disclosure vulnerability that exposes the tls_acme_eab_mac_key value through the sys/config/state/sanitized endpoint. Callers of the sanitized configuration endpoint can retrieve the ACME External Account Binding MAC key used for TLS listener certificates, letting them bind to the operator's ACME account.
- CVE-2026-115362Low
OpenBao before 2.6.4 and 2.7.x before 2.7.1 does not check Secret ID expiration at use in the AppRole auth method, leaving expired Secret IDs valid until the periodic tidy removes them. An attacker holding an expired, untidied Secret ID can log in and gain access beyond its TTL.
- CVE-2026-115361Medium
An ACL bypass vulnerability in OpenBao silently drops explicit deny rules based on forbidden identity metadata templates within wildcard grants. An attacker whose identity metadata contains wildcard or path segments can access paths that should be denied within the broader wildcard-granted scope.
Original NVD description (English source)
OpenBao is an open source identity-based secrets management system. Prior to version 2.4.2, OpenBao's audit log did not appropriately redact fields when relevant subsystems sent []byte response parameters rather than strings. This includes, but is not limited to sys/raw with use of encoding=base64, all data would be emitted unredacted to the audit log, and Transit, when performing a signing operation with a derived Ed25519 key, would emit public keys to the audit log. This issue has been patched in OpenBao 2.4.2.
