CVE-2026-90462 (GCVE-0-2026-90462)

Vulnerability from cvelistv5 – Published: 2026-09-22 15:50 – Updated: 2026-09-22 17:25

Title
Sssd: sssd: fail-open in ldap ppolicy access check allows continued authorization
Summary
A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` including `ppolicy` or `lockout`, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache an allow decision, permitting continued authorization for a deleted or deprovisioned user. A remote attacker with prior valid account context could exploit this to maintain access to information and potentially make limited modifications to resources that should no longer be available.

Title
Zammad: Titles of knowledge base answers will be shown across all categories via the global search
Summary
Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, when multiple KB categories have different editor roles assigned, a user with knowledge_base.editor in one category can see answer titles and updated_at timestamps from categories they do not have editor access to , via the global quick search. Category names are not leaked, and opening the answer returns "Page not found," but the title alone may disclose sensitive information. This vulnerability is fixed in 7.0.2.

Title
Wagtail: Improper restriction handling on Pages admin API
Summary
Wagtail is an open source content management system built on Django. Prior to versions 7.0.9, 7.3.4, 7.4.3, and 8.0rc2 on their respective release lines, the internal Pages admin API returns page fields declared in api_fields without sufficient access control, allowing a user with Wagtail admin access to retrieve restricted draft and live page content. This issue is fixed in versions 7.0.9, 7.3.4, 7.4.3, and 8.0rc2.

Mitigation MIT-46
Architecture and Design

Strategy: Separation of Privilege

  • Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation
Implementation

Always check to see if you have successfully accessed a resource or system functionality, and use proper error handling if it is unsuccessful. Do this even when you are operating in a highly privileged mode, because errors or environmental conditions might still cause a failure. For example, environments with highly granular permissions/privilege models, such as Windows or Linux capabilities, can cause unexpected failures.
