CVE-2026-34319 2026-04-22 N/A 5.0 MEDIUM
Vulnerability in the MySQL Shell product of Oracle MySQL (component: Shell: Core Client). Supported versions that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where MySQL Shell executes to compromise MySQL Shell. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Shell. CVSS 3.1 Base Score 5.0 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H).
CVE-2026-39851 1 Saleor 1 Saleor 2026-04-20 N/A 4.3 MEDIUM
Saleor is an e-commerce platform. From 2.10.0 to before 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118, the requestEmailChange() mutation was revealing the existence of user-provided email addresses in error messages. This vulnerability is fixed in 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118.
CVE-2026-40485 2026-04-20 N/A 5.3 MEDIUM
ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the public API login endpoint (/api/public/user/login) returns distinguishable HTTP response codes based on whether a username exists: 404 for non-existent users and 401 for valid users with incorrect passwords. An unauthenticated attacker can exploit this difference to enumerate valid usernames, with no rate limiting or account lockout to impede the process. This issue has been fixed in version 7.2.0.
CVE-2026-24468 2026-04-20 N/A 5.3 MEDIUM
OpenAEV is an open source platform allowing organizations to plan, schedule and conduct cyber adversary simulation campaign and tests. Starting in version 1.11.0 and prior to version 2.0.13, the /api/reset endpoint behaves differently depending on whether the supplied username exists in the system. When a non-existent email is provided in the login parameter, the endpoint returns an HTTP 400 response (Bad Request). When a valid email is supplied, the endpoint responds with HTTP 200. This difference in server responses creates an observable discrepancy that allows an attacker to reliably determine which emails are registered in the application. By automating requests with a list of possible email addresses, an attacker can quickly build a list of valid accounts without any authentication. The endpoint should return a consistent response regardless of whether the username exists in order to prevent account enumeration. Version 2.0.13 fixes this issue.
CVE-2025-12455 1 Opentext 1 Vertica 2026-04-17 N/A 7.5 HIGH
Observable response discrepancy vulnerability in OpenText™ Vertica allows Password Brute Forcing.   The vulnerability could lead to Password Brute Forcing in Vertica management console application.This issue affects Vertica: from 10.0 through 10.X, from 11.0 through 11.X, from 12.0 through 12.X.
CVE-2026-34264 2026-04-17 N/A 6.5 MEDIUM
During authorization checks in SAP Human Capital Management for SAP S/4HANA, the system returns specific messages. Due to this, an authenticated user with low privileges could guess and enumerate the content shown, beyond their authorized scope. This leads to disclosure of sensitive information causing a high impact on confidentiality, while integrity and availability are unaffected.
CVE-2025-2910 2026-04-15 N/A 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-2025-3092 2026-04-15 N/A 7.5 HIGH
An unauthenticated remote attacker can enumerate valid user names from an unprotected endpoint.
CVE-2025-34155 2026-04-15 N/A N/A
Tibbo AggreGate Network Manager < 6.40.05 contains an observable response discrepancy in its login functionality. Authentication failure messages differ based on whether a supplied username exists or not, allowing an unauthenticated remote attacker to infer valid account identifiers. This can facilitate user enumeration and increase the likelihood of targeted brute-force or credential-stuffing attacks.
CVE-2025-42903 2026-04-15 N/A 4.3 MEDIUM
A vulnerability in SAP Financial Service Claims Management RFC function ICL_USER_GET_NAME_AND_ADDRESS allows user enumeration and potential disclosure of personal data through response discrepancies, causing low impact on confidentiality with no impact on integrity or availability.
CVE-2025-62181 2026-04-15 N/A 5.3 MEDIUM
Pega Platform versions 7.1.0 through Infinity 25.1.0 are affected by a User Enumeration. This issue occurs during user authentication process, where a difference in response time could allow a remote unauthenticated user to determine if a username is valid or not. This only applies to deprecated basic-authentication feature and other more secure authentication mechanisms are recommended. A fix is being provided in the 24.1.4, 24.2.4, and 25.1.1 patch releases. Please note: Basic credentials authentication service type is deprecated started in 24.2 version: https://docs.pega.com/bundle/platform/page/platform/release-notes/security/whats-new-security-242.html.
CVE-2024-12663 2026-04-15 2.6 LOW 3.7 LOW
A vulnerability classified as problematic was found in funnyzpc Mee-Admin up to 1.6. This vulnerability affects unknown code of the file /mee/login of the component Login. The manipulation of the argument username leads to observable response discrepancy. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
CVE-2024-40627 2026-04-15 N/A 5.8 MEDIUM
Fastapi OPA is an opensource fastapi middleware which includes auth flow. HTTP `OPTIONS` requests are always allowed by `OpaMiddleware`, even when they lack authentication, and are passed through directly to the application. `OpaMiddleware` allows all HTTP `OPTIONS` requests without evaluating it against any policy. If an application provides different responses to HTTP `OPTIONS` requests based on an entity existing (such as to indicate whether an entity is writable on a system level), an unauthenticated attacker could discover which entities exist within an application. This issue has been addressed in release version 2.0.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2025-46390 2026-04-15 N/A 7.5 HIGH
CWE-204: Observable Response Discrepancy
CVE-2025-58442 2026-04-15 N/A 5.3 MEDIUM
Saleor is an e-commerce platform. Starting in version 3.21.0 and prior to version 3.21.16, requesting certain fields in the response of `accountRegister` may result in errors that could unintentionally reveal whether a user with the provided email already exists in Saleor. Version 3.21.16 fixes the issue. As a workaround, rate-limit the mutation to reduce the impact.
CVE-2025-23214 2026-04-15 N/A N/A
Cosmos provides users the ability self-host a home server by acting as a secure gateway to your application, as well as a server manager. By monitoring the error code returned in the login, it is possible to figure out whether a user exist or not in the database. Patched in 0.17.7.
CVE-2025-48015 2026-04-15 N/A 3.7 LOW
Failed login response could be different depending on whether the username was local or central.
CVE-2024-39211 2026-04-15 N/A 5.3 MEDIUM
Kaiten 57.128.8 allows remote attackers to enumerate user accounts via a crafted POST request, because a login response contains a user_email field only if the user account exists.
