CVE-2019-19030 1 Linuxfoundation 1 Harbor 2025-04-14 5.3 Medium
Cloud Native Computing Foundation Harbor before 1.10.3 and 2.x before 2.0.1 allows resource enumeration because unauthenticated API calls reveal (via the HTTP status code) whether a resource exists.
CVE-2025-30150 2025-04-08 N/A
Shopware 6 is an open commerce platform based on Symfony Framework and Vue. Through the store-api it is possible as a attacker to check if a specific e-mail address has an account in the shop. Using the store-api endpoint /store-api/account/recovery-password you get the response, which indicates clearly that there is no account for this customer. In contrast you get a success response if the account was found. This vulnerability is fixed in Shopware 6.6.10.3 or 6.5.8.17. For older versions of 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

CVE-2025-31124 2025-04-01 5.3 Medium
Zitadel is open-source identity infrastructure software. ZITADEL administrators can enable a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report "Username or Password invalid". While the setting was correctly respected during the login flow, the user's username was normalized leading to a disclosure of the user's existence. This vulnerability is fixed in 2.71.6, 2.70.8, 2.69.9, 2.68.9, 2.67.13, 2.66.16, 2.65.7, 2.64.6, and 2.63.9.
CVE-2025-2910 2025-03-28 N/A
User enumeration in the password reset module of the MeetMe authentication service in versions prior to 2024-09 allows an attacker to determine whether an email address is registered through specific error messages.
CVE-2023-46170 1 Ibm 2 Ds8900f, Ds8900f Firmware 2025-03-11 6.5 Medium
IBM DS8900F HMC 89.21.19.0, 89.21.31.0, 89.30.68.0, 89.32.40.0, and 89.33.48.0 could allow an authenticated user to arbitrarily read files after enumerating file names.
CVE-2022-39228 1 Vantage6 1 Vantage6 2025-03-07 5.3 Medium
vantage6 is a privacy preserving federated learning infrastructure for secure insight exchange. vantage6 does not inform the user of wrong username/password combination if the username actually exists. This is an attempt to prevent bots from obtaining usernames. However, if a wrong password is entered a number of times, the user account is blocked temporarily. This issue has been fixed in version 3.8.0.
CVE-2023-37413 1 Ibm 1 Aspera Faspex 2025-03-04 5.3 Medium

CVE-2025-24023 2025-03-03 3.7 Low
Flask-AppBuilder is an application development framework. Prior to 4.5.3, Flask-AppBuilder allows unauthenticated users to enumerate existing usernames by timing the response time from the server when brute forcing requests to login. This vulnerability is fixed in 4.5.3.
CVE-2024-36996 1 Splunk 3 Splunk, Splunk Cloud Platform, Splunk Enterprise 2025-02-28 5.3 Medium
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.109, an attacker could determine whether or not another user exists on the instance by deciphering the error response that they would likely receive from the instance when they attempt to log in. This disclosure could then lead to additional brute-force password-guessing attacks. This vulnerability would require that the Splunk platform instance uses the Security Assertion Markup Language (SAML) authentication scheme.
