CVE-2026-25138 1 Cern 1 Rucio 2026-06-17 N/A 5.3 MEDIUM
Rucio is a software framework that provides functionality to organize, manage, and access large volumes of scientific data using customizable policies. Prior to versions 35.8.3, 38.5.4, and 39.3.1, the WebUI login endpoint returns distinct error messages depending on whether a supplied username exists, allowing unauthenticated attackers to enumerate valid usernames. Versions 35.8.3, 38.5.4, and 39.3.1 fix the issue.
CVE-2026-24664 1 Gunet 1 Open Eclass Platform 2026-06-17 N/A 5.3 MEDIUM
The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, a username enumeration vulnerability allows unauthenticated attackers to identify valid user accounts by analyzing differences in the login response behavior. This issue has been patched in version 4.2.
CVE-2026-24468 2026-06-17 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-2026-24097 1 Checkmk 1 Checkmk 2026-06-17 N/A 4.3 MEDIUM
Improper permission enforcement in Checkmk versions 2.4.0 before 2.4.0p23, 2.3.0 before 2.3.0p43, and 2.2.0 (EOL) allows authenticated users to enumerate existing hosts by observing different HTTP response codes in agent-receiver/register_existing endpoint, which could lead to information disclosure.
CVE-2026-23511 1 Zitadel 1 Zitadel 2026-06-17 N/A 5.3 MEDIUM
ZITADEL is an open source identity management platform. Prior to 4.9.1 and 3.4.6, a user enumeration vulnerability has been discovered in Zitadel's login interfaces. An unauthenticated attacker can exploit this flaw to confirm the existence of valid user accounts by iterating through usernames and userIDs. This vulnerability is fixed in 4.9.1 and 3.4.6.
CVE-2026-21484 1 Mintplexlabs 1 Anythingllm 2026-06-17 N/A 5.3 MEDIUM
AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. Prior to commit e287fab56089cf8fcea9ba579a3ecdeca0daa313, the password recovery endpoint returns different error messages depending on whether a username exists, so enabling username enumeration. Commit e287fab56089cf8fcea9ba579a3ecdeca0daa313 fixes this issue.
CVE-2025-9109 1 Portabilis 1 I-diario 2026-06-17 2.6 LOW 3.7 LOW
A security flaw has been discovered in Portabilis i-Diario up to 1.5.0. Affected by this vulnerability is an unknown functionality of the file /password/email of the component Password Recovery Endpoint. The manipulation results in observable response discrepancy. It is possible to launch the attack remotely. This attack is characterized by high complexity. The exploitation appears to be difficult. The exploit has been released to the public and may be exploited.
CVE-2025-69243 1 Raytha 1 Raytha 2026-06-17 N/A 5.3 MEDIUM
Raytha CMS is vulnerable to User Enumeration in password reset functionality. Difference in messages could allow an attacker to determine if the login is valid or not, enabling a brute force attack with valid logins. This issue was fixed in version 1.5.0.
CVE-2025-67807 1 Sagedpw 1 Sage Dpw 2026-06-17 N/A 4.7 MEDIUM
The login mechanism of Sage DPW 2025_06_004 displays distinct responses for valid and invalid usernames, allowing enumeration of existing accounts in versions before 2021_06_000. On-premise administrators can toggle this behaviour in newer versions.
CVE-2025-67806 1 Sagedpw 1 Sage Dpw 2026-06-17 N/A 3.7 LOW
The login mechanism of Sage DPW 2021_06_004 displays distinct responses for valid and invalid usernames, allowing enumeration of existing accounts in versions before 2021_06_000. On-premise administrators can toggle this behavior in newer versions.
CVE-2025-65899 1 Difuse 1 Kalmia 2026-06-17 N/A 5.3 MEDIUM
Kalmia CMS version 0.2.0 contains a user enumeration vulnerability in its authentication mechanism. The application returns different error messages for invalid users (user_not_found) versus valid users with incorrect passwords (invalid_password). This observable response discrepancy allows unauthenticated attackers to enumerate valid usernames on the system.
CVE-2025-62512 1 Piwigo 1 Piwigo 2026-06-17 N/A 5.3 MEDIUM
Piwigo is an open source photo gallery application for the web. In version 15.5.0 and likely earlier 15.x releases, the password reset functionality in Piwigo allows an unauthenticated attacker to determine whether a given username or email address exists in the system. The endpoint at password.php?action=lost returns distinct messages for valid vs. invalid accounts, enabling user enumeration. As of time of publication, no known patches are available.
CVE-2025-5485 2026-06-17 N/A 8.6 HIGH
User names used to access the web management interface are limited to the device identifier, which is a numerical identifier no more than 10 digits. A malicious actor can enumerate potential targets by incrementing or decrementing from known identifiers or through enumerating random digit sequences.
CVE-2025-56764 1 Trivisionsecurity 2 Trivision Nc-227wf, Trivision Nc-227wf Firmware 2026-06-17 N/A 5.3 MEDIUM
Trivision NC-227WF firmware 5.80 (build 20141010) login mechanism reveals whether a username exists or not by returning different error messages ("Unknown user" vs. "Wrong password"), allowing an attacker to enumerate valid usernames.
CVE-2025-54834 1 Opexustech 1 Foiaxpress Public Access Link 2026-06-17 N/A 5.3 MEDIUM
OPEXUS FOIAXpress Public Access Link (PAL) version v11.1.0 allows an unauthenticated, remote attacker to query the /App/CreateRequest.aspx endpoint to check for the existence of valid usernames. There are no rate-limiting mechanisms in place.
CVE-2025-54129 1 Psu 1 Haxiam 2026-06-17 N/A 4.3 MEDIUM
HAXiam is a packaging wrapper for HAXcms which allows anyone to spawn their own microsite management platform. In versions 11.0.4 and below, the application returns a 200 response when requesting the data of a valid user and a 404 response when requesting the data of an invalid user. This can be used to infer the existence of valid user accounts. An authenticated attacker can use automated tooling to brute force potential usernames and use the application's response to identify valid accounts. This can be used in conjunction with other vulnerabilities, such as the lack of authorization checks, to enumerate and deface another user's sites. This is fixed in version 11.0.5.
CVE-2025-52899 1 Enalean 1 Tuleap 2026-06-17 N/A 5.3 MEDIUM
Tuleap is an Open Source Suite created to facilitate management of software development and collaboration. In Tuleap Community Edition prior to version 16.9.99.1750843170 and Tuleap Enterprise Edition prior to 16.8-4 and 16.9-2, the forgot password form allows for user enumeration. This is fixed in Tuleap Community Edition version 16.9.99.1750843170 and Tuleap Enterprise Edition 16.8-4 and 16.9-2.
CVE-2025-49187 1 Sick 1 Field Analytics 2026-06-17 N/A 5.3 MEDIUM
For failed login attempts, the application returns different error messages depending on whether the login failed due to an incorrect password or a non-existing username. This allows an attacker to guess usernames until they find an existing one.
CVE-2025-48015 2026-06-17 N/A 3.7 LOW
Failed login response could be different depending on whether the username was local or central.
CVE-2025-46736 1 Umbraco 1 Umbraco Cms 2026-06-17 N/A 5.3 MEDIUM
Umbraco is a free and open source .NET content management system. Prior to versions 10.8.10 and 13.8.1, based on an analysis of the timing of post login API responses, it's possible to determine whether an account exists. The issue is patched in versions 10.8.10 and 13.8.1. No known workarounds are available.
