Vulnerability from github – Published: 2026-05-14 06:31 – Updated: 2026-05-14 06:31
VLAI
Details

The Fluent Forms plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to, and including, 6.1.21. This is due to the SubmissionPolicy class authorizing submission-level actions (read, modify, delete, add notes) based on a user-supplied form_id query parameter. This makes it possible for authenticated attackers, with Fluent Forms Manager access restricted to specific forms, to read, modify status, add notes to, and permanently delete form submissions belonging to any other form by spoofing the form_id parameter to a form they are authorized for.

Vulnerability from github – Published: 2023-04-05 21:30 – Updated: 2025-02-13 21:31
VLAI
Details

Bhima version 1.27.0 allows an attacker authenticated with normal user permissions to view sensitive data of other application users and data that should only be viewed by the administrator. This is possible because the application is vulnerable to IDOR, it does not properly validate user permissions with respect to certain actions the user can perform.

Vulnerability from github – Published: 2025-07-14 19:24 – Updated: 2025-07-22 18:33
VLAI
Summary
Indico vulnerability allows attackers to bulk dump user details
Details

Impact

An endpoint used to display details of users listed in certain fields (such as ACLs) could be misused to dump basic user details (such as name, affiliation and email) in bulk.

[!TIP] If your instance allows everyone to create a user account, and you wish to truly restrict access to these user details, consider restricting user search to managers. You can find details on the newly introduced indico.conf setting ALLOW_PUBLIC_USER_SEARCH in our documentation.

Patches

You should to update to Indico 3.3.7 as soon as possible. See the docs for instructions on how to update.

Workarounds

It is possible to restrict access to the affected endpoints (e.g. in the webserver config), but doing so would break certain form fields which could no longer show the details of the users listed in those fields, so upgrading instead is highly recommended.

Credits

This vulnerability was identified during a security assessment conducted as part of the Red Team Residency Program at RNP (Rede Nacional de Ensino e Pesquisa). The research and testing were performed by a security researcher working under RNP’s authorization and coordination. Special acknowledgment goes to the RNP Security Team, which provided the infrastructure, methodology, and ethical oversight for this work.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
