CVE-2026-92772 Details
Description
Leantime before 3.9.6 contains an authorization bypass vulnerability in the HTMX plugin install endpoint that lacks permission validation. Authenticated users with limited roles can install marketplace plugins and control arbitrary properties including identifier, version, and license key to deploy malicious plugins.
A vulnerability exists in Leantime versions prior to 3.9.6, allowing authorization bypass in the HTMX plugin installation endpoint. This flaw enables authenticated users with limited roles to install marketplace plugins by exploiting the lack of permission validation. The vulnerability arises from the endpoint's failure to enforce role-based access, allowing unauthorized plugin installations. Additionally, the absence of a property allowlist in the plugin model construction process enables the manipulation of plugin identifiers, versions, and license keys, potentially leading to the deployment of malicious plugins.
Users can update to Leantime version 3.9.6 or later, where this vulnerability has been fixed.
