Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

AC-3 requires enforcement of approved authorizations for access to information and resources, directly addressing the improper authorization in the page content retrieval feature that allows unauthorized access to non-public data.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates identification, reporting, and timely remediation of flaws, enabling application of patches released in Connect-CMS versions 1.41.1 and 2.41.1 to fix this vulnerability.

AC-6 Least Privilege partial match

prevent

AC-6 enforces least privilege, restricting access to only necessary content retrieval operations and mitigating unauthorized exposure even if authorization checks are flawed.

Deeper analysisAI

CVE-2026-32299 is an improper authorization vulnerability (CWE-284) in the page content retrieval feature of Connect-CMS, an open-source content management system. It affects versions in the 1.x series up to and including 1.41.0, as well as versions in the 2.x series up to and including 2.41.0. The flaw enables unauthorized access to non-public information through inadequate checks during content retrieval operations.

The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating it can be exploited remotely over the network by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows attackers to retrieve sensitive, non-public page content, potentially exposing confidential data hosted on affected Connect-CMS instances without impacting integrity or availability.

Mitigation is available via patches released for the affected branches: version 1.41.1 for the 1.x series and version 2.41.1 for the 2.x series. Security practitioners should upgrade to these versions immediately.
