GHSA-RXP7-9Q75-VJ3P
Vulnerability from github – Published: 2025-08-08 14:44 – Updated: 2025-08-11 13:56Impact
OpenBao's Login Multi-Factor Authentication (MFA) system allows enforcing MFA using Time-based One Time Password (TOTP). Due to normalization applied by the underlying TOTP library, codes were accepted which could contain whitespace; this whitespace could bypass internal rate limiting of the MFA method and allow reuse of existing MFA codes.
Patches
OpenBao v2.3.2 will patch this issue.
Workarounds
Use of rate-limiting quotas can limit an attacker's ability to exploit this: https://openbao.org/api-docs/system/rate-limit-quotas/
References
This issue was disclosed to HashiCorp and is the OpenBao equivalent of the following tickets:

GHSA-V5GF-VPJC-PC7W
Vulnerability from github – Published: 2026-10-07 20:29 – Updated: 2026-10-07 20:29Impact
An unauthenticated attacker who knows an account’s email address or username could trigger Payload’s account lockout mechanism and prevent that user from signing in.
You are affected if:
- Using an affected Payload version with an auth-enabled collection that uses local authentication and account lockout.
Applications that do not use Payload local authentication are not affected.
Patches
Successful password resets now clear the account’s lockout state. The forgot-password flow also enforces a configurable minimum interval between reset emails, which defaults to 15 seconds.
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.

The middleware accepts the API token (Conf.Api.Token) via an Authorization header (Token/Bearer) or a ?token= query parameter, and neither path is protected by the application's CAPTCHA/lockout mechanism (NeedCaptcha/WrongAuthCount).

Mitigation
- Common protection mechanisms include:
- Disconnecting the user after a small number of failed attempts
- Implementing a timeout
- Locking out a targeted account
- Requiring a computational task on the user's part.
Mitigation MIT-4
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
- Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
CAPEC-16: Dictionary-based Password Attack
An attacker tries each of the words in a dictionary as passwords to gain access to the system via some user's account. If the password chosen by the user was a word within the dictionary, this attack will be successful (in the absence of other mitigations). This is a specific instance of the password brute forcing attack pattern.
Dictionary Attacks differ from similar attacks such as Password Spraying (CAPEC-565) and Credential Stuffing (CAPEC-600), since they leverage unknown username/password combinations and don't care about inducing account lockouts.
CAPEC-49: Password Brute Forcing
An adversary tries every possible value for a password until they succeed. A brute force attack, if feasible computationally, will always be successful because it will essentially go through all possible passwords given the alphabet used (lower case letters, upper case letters, numbers, symbols, etc.) and the maximum length of the password.
CAPEC-560: Use of Known Domain Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate credentials (e.g. userID/password) to achieve authentication and to perform authorized actions under the guise of an authenticated user or service.
CAPEC-565: Password Spraying
In a Password Spraying attack, an adversary tries a small list (e.g. 3-5) of common or expected passwords, often matching the target's complexity policy, against a known list of user accounts to gain valid credentials. The adversary tries a particular password for each user account, before moving onto the next password in the list. This approach assists the adversary in remaining undetected by avoiding rapid or frequent account lockouts. The adversary may then reattempt the process with additional passwords, once enough time has passed to prevent inducing a lockout.
CAPEC-600: Credential Stuffing
An adversary tries known username/password combinations against different systems, applications, or services to gain additional authenticated access. Credential Stuffing attacks rely upon the fact that many users leverage the same username/password combination for multiple systems, applications, and services.
CAPEC-652: Use of Known Kerberos Credentials
An adversary obtains (i.e. steals or purchases) legitimate Kerberos credentials (e.g. Kerberos service account userID/password or Kerberos Tickets) with the goal of achieving authenticated access to additional systems, applications, or services within the domain.
CAPEC-653: Use of Known Operating System Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate operating system credentials (e.g. userID/password) to achieve authentication and to perform authorized actions on the system, under the guise of an authenticated user or service. This applies to any Operating System.
