CVE-2026-93335
Vault vulnerable to ACL deny bypass via trailing slash
CVSS Score
6.5
EPSS Score
0.0%
EPSS Percentile
0th
Vault Community Edition and Vault Enterprise did not consistently apply explicit ACL policy deny rules to request paths that differ only by a trailing slash. This may allow an authenticated user who holds a broader delete permission on system configuration paths to disable a secrets engine, auth method, or audit device that a more specific deny rule was intended to protect. This vulnerability (CVE-2026-93335) is fixed in Vault Community Edition 2.2.2 and Vault Enterprise 2.2.2, 1.21.14, and 1.19.25.
