CVE-2026-4857 (GCVE-0-2026-4857)

Vulnerability from cvelistv5 – Published: 2026-04-15 18:08 – Updated: 2026-04-16 03:55

Title
SailPoint IdentityIQ Debug UI Incorrect Authorization
Summary
IdentityIQ 8.5, all IdentityIQ 8.5 patch levels prior to 8.5p2, IdentityIQ 8.4, and all IdentityIQ 8.4 patch levels prior to 8.4p4 allow authenticated users assigned the Debug Pages Read Only capability or any custom capability with the ViewAccessDebugPage SPRight to incorrectly create new IdentityIQ objects.  Until a remediating security fix or patches containing this security fix are installed, the Debug Pages Read Only capability and any custom capabilities that contain the ViewAccessDebugPage SPRight should be unassigned from all identities and workgroups.

CVE-2026-4274 (GCVE-0-2026-4274)

Vulnerability from cvelistv5 – Published: 2026-03-26 10:43 – Updated: 2026-03-26 13:58

Title
Insufficient authorization in shared channel membership sync grants team-level access instead of channel-level access
Summary
Mattermost versions 11.2.x <= 11.2.2, 10.11.x <= 10.11.10, 11.4.x <= 11.4.0, 11.3.x <= 11.3.1 fail to restrict team-level access when processing membership sync from a remote cluster, which allows a malicious remote cluster to grant a user access to an entire private team instead of only the shared channel via sending crafted membership sync messages that trigger team membership assignment.

CVE-2026-4265 (GCVE-0-2026-4265)

Guest user can upload files without permission across teams
Summary
Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2, 10.11.x <= 10.11.10 fail to validate team-specific upload_file permissions which allows a guest user to post files in channels where they lack upload_file permission via uploading files in a team where they have permission and reusing the file metadata in a POST request to a different team.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

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.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
