CVE-2026-63132: Observable Timing Discrepancy

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 a...

CVE-2026-63131: Incorrect Authorization

OpenBao is an open source identity-based secrets management system. Prior to 2.6.0, OpenBao's vault/policy/acl.go could evaluate a broader wildcard ACL grant before more-specific trailing-wildcard ACL paths with capabilities = "deny" for a LIST operation. When a parent path permitted LIST and a...

CVE-2026-77285: Insertion of Sensitive Information into Log File

OpenBao is an open source identity-based secrets management system. Prior to 2.6.0, OpenBao Agent's exec rendering mode could write secrets from envtemplate to standard output when command/agent/exec/exec.go re-created the template runner after repeated rendering failures, primarily after...

GHSA-XP3C-3JW3-4VCR OpenBao Skips Stricter Deny Policy for LIST operations

Impact When a policy operator has written capabilities = "deny" on a path with a trailing wildcard but allowed a broader list operation e.g., a deny on secrets/metadata/restricted/ but allowed list on secrets/metadata/, OpenBao would incorrectly allow the operation. This did not impact other...

Timing Attack

Overview github.com/hashicorp/vault/http is an a tool for securely accessing secrets. Affected versions of this package are vulnerable to Timing Attack via the recovery token comparison in handleLogicalRecovery in http/logical.go. An attacker can extract the single recovery token and use it to...

OpenBao's Recovery Mode Vulnerable To Token Leakage via Timing Attack

Impact When running in the highly privileged recovery mode, OpenBao was vulnerable to a timing attack against the single recovery token. This allowed an attacker to extract the recovery token and use it to perform operations against the OpenBao instance, including reading or modification of data...

GHSA-59W7-V8RR-PR4P OpenBao's Templated Policies Allow Privilege Escalation via Wildcard Characters

Impact ACL Policies OpenBao supports "templated polices": Policies with placeholders that are replaced at evaluation time. This allows you to write a single policy which e.g. grants user "alice" access to all entries in a key value engine prefixed with alice/ while granting "bob" access to bob/,...
