CVE-2025-55001
CWE-156Published: August 9, 2025· Updated: Jun 17, 2026
Official Description
OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 2.3.1 and below, OpenBao allowed the assignment of policies and MFA attribution based upon entity aliases, chosen by the underlying auth method. When the username_as_alias=true parameter in the LDAP auth method was in use, the caller-supplied username was used verbatim without normalization, allowing an attacker to bypass alias-specific MFA requirements. This issue was fixed in version 2.3.2. To work around this, remove all usage of the username_as_alias=true parameter and update any entity aliases accordingly.
Technical Analysis
CVE-2025-55001 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 6.5.
