CVE-2026-89322 Alta · 7.2 CWE-178 07/10/2026

Vault ACL Policy Evaluation May Allow Bypass of Deny Restrictions

Vault and Vault Enterprise did not consistently evaluate ACL policies against the canonical form of resource and policy names. This may allow an authenticated user with delegated permissions to bypass an explicit deny restriction and access a protected resource or assign a denied policy, potentially leading to privilege escalation. This vulnerability (CVE-2026-89322) is fixed in Vault Community Edition 2.1.2, and Vault Enterprise 2.1.2, 1.21.12, 1.20.17, and 1.19.23.

CVE-2026-105818 Média · 5.9 CWE-345 07/10/2026

Vault PKI ACME Issues Certificate With Unvalidated SANs

Vault's PKI secrets engine ACME server did not restrict certificate identities that ACME challenges do not validate when issuing certificates under the default directory policy. This may allow an ACME client to obtain a certificate containing unverified identity claims, potentially enabling impersonation toward systems that trust certificates issued by the affected Vault PKI mount. This vulnerability (CVE-2026-105818) is fixed in Vault Community Edition 2.1.2, and Vault Enterprise 2.1.2, 1.21.12, 1.20.17, and 1.19.23.

CVE-2026-105816 Alta · 8.0 CWE-22 07/10/2026

Vault Vulnerable to Arbitrary Code Execution via Plugin Catalog Entries Restored From Raft Snapshots

Vault and Vault Enterprise did not consistently verify that stored plugin catalog entries reference binaries within the configured plugin directory. When Vault uses Shamir seals and has an external plugin directory configured, a privileged operator able to restore an Integrated Storage (Raft) snapshot may be able to execute arbitrary code on the Vault host. This vulnerability (CVE-2026-105816) is fixed in Vault Community Edition 2.1.2, and Vault Enterprise 2.1.2, 1.21.12, 1.20.17, and 1.19.23.

CVE-2026-5006 Média · 6.8 CWE-639 24/08/2026

Vault Vulnerable to Privilege Escalation via Slash Injection in Templated Policy Paths

A vulnerability was identified in HashiCorp Vault and Vault Enterprise (“Vault”) such that an authenticated attacker may manipulate an identity value referenced by a templated policy path to gain unintended access to Vault paths. An attacker who can control the referenced identity value may include slash ({{/}}) characters that Vault interprets as additional path segments when rendering the policy. This vulnerability, CVE-2026-5006, was fixed in Vault Community Edition 2.0.4 and Vault Enterprise 2.0.4, 1.21.9, 1.20.14, and 1.19.20.

CVE-2026-5051 Média · 4.4 CWE-22 01/07/2026

Audit Log Plugin Directory Guard Bypass via Legacy path Option

HashiCorp Vault and Vault Enterprise prior to 2.0.1 audit device validation logic did not consistently apply plugin directory protections when the legacy file audit path option was used. This vulnerability (CVE-2026-5051) is fixed in 2.0.1, 1.21.6, 1.20.11, and 1.19.17.

CVE-2026-5807 Alta · 7.5 CWE-770 17/04/2026

Vault Vulnerable to Denial-of-Service via Unauthenticated Root Token Generation/Rekey Operations

Vault is vulnerable to a denial-of-service condition where an unauthenticated attacker can repeatedly initiate or cancel root token generation or rekey operations, occupying the single in-progress operation slot. This prevents legitimate operators from completing these workflows. This vulnerability, CVE-2026-5807, is fixed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0.

CVE-2026-5052 Alta · 8.6 CWE-918 17/04/2026

Vault Vulnerable to Server-Side Request Forgery in ACME Challenge Validation via Attacker-Controlled DNS

Vault’s PKI engine’s ACME validation did not reject local targets when issuing http-01 and tls-alpn-01 challenges. This may lead to these requests being sent to local network targets, potentially leading to information disclosure. Fixed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0, 1.21.5, 1.20.10, and 1.19.16.

CVE-2026-4525 Alta · 8.8 CWE-201 17/04/2026

Vault Token Leaked to Backends via Authorization: Bearer Passthrough Header

If a Vault auth mount is configured to pass through the "Authorization" header, and the "Authorization" header is used to authenticate to Vault, Vault forwarded the Vault token to the auth plugin backend. Fixed in 2.0.0, 1.21.5, 1.20.10, and 1.19.16.

CVE-2026-3605 Alta · 8.1 CWE-288 17/04/2026

Vault KVv2 Metadata and Secret Deletion Policy Bypass Denial-of-Service

An authenticated user with access to a kvv2 path through a policy containing a glob may be able to delete secrets they were not authorized to read or write, resulting in denial-of-service. This vulnerability did not allow a malicious user to delete secrets across namespaces, nor read any secret data. Fxed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0, 1.21.5, 1.20.10, and 1.19.16.

CVE-2025-12044 Alta · 7.5 CWE-770 23/10/2025

Vault Vulnerable to Denial of Service Due to Rate Limit Regression

Vault and Vault Enterprise (“Vault”) are vulnerable to an unauthenticated denial of service when processing JSON payloads. This occurs due to a regression from a previous fix for [+HCSEC-2025-24+|https://discuss.hashicorp.com/t/hcsec-2025-24-vault-denial-of-service-though-complex-json-payloads/76393] which allowed for processing JSON payloads before applying rate limits. This vulnerability, CVE-2025-12044, is fixed in Vault Community Edition 1.21.0 and Vault Enterprise 1.16.27, 1.19.11, 1.20.5, and 1.21.0.

CVE-2025-11621 Alta · 8.1 CWE-288 23/10/2025

Vault AWS auth method bypass due to AWS client cache

Vault and Vault Enterprise’s (“Vault”) AWS Auth method may be susceptible to authentication bypass if the role of the configured bound_principal_iam is the same across AWS accounts, or uses a wildcard. This vulnerability, CVE-2025-11621, is fixed in Vault Community Edition 1.21.0 and Vault Enterprise 1.21.0, 1.20.5, 1.19.11, and 1.16.27
