Technical description

Missing Authorization (CWE-862) in Kibana can lead to unauthorized information disclosure via Privilege Abuse (CAPEC-122). A user with limited feature privileges can access workflow execution outputs in their Kibana space without the authorization required to do so through the documented API. The accessible data may include sensitive information returned by workflow steps, such as results from connected data sources that the caller would not otherwise be authorized to access.

——0Taiga 6.10.1 contains a missing authorization vulnerability that allows unauthenticated attackers to disclose the full member roster and internal workflow configuration of any private project by supplying a project ID to the filters_data API endpoints on UserStory, Task, Issue, and Epic viewsets. Attackers can send unauthenticated GET requests to the filters_data endpoints with sequential integer project IDs to enumerate private project membership details including user IDs, full names, and gravatar hashes, bypassing the access controls that correctly restrict other project API endpoints.5h CVE-2026-630924.3 MED

——0kirby-modules through 5.5.7, fixed in commit 315417e, contains an information disclosure vulnerability that allows any authenticated Kirby Panel user to retrieve the full plaintext commercial license key by sending a GET request to the modules/activate dialog endpoint. The plugin's activate dialog handler in lib/areas.php returns the complete key via ModulesLicense::readKey() without performing an administrator check, as the dialog is gated only by the access.system permission which defaults to true for all non-admin roles, enabling attackers to use the disclosed key to activate the plugin on arbitrary third-party installations.5h CVE-2026-476888.2 HIG

——0FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the `clearAES` and `clearPMTasks` methods in `FOGPage` can be invoked by an unauthenticated attacker via a single HTTP GET request through the public `client` node endpoint. This allows remote wiping of host AES encryption credentials and deletion of all power management scheduled tasks, with no login, session, or CSRF token required. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.5h CVE-2026-47657—

——0HumHub is an Open Source Enterprise Social Network. In versions 1.13.0 through 1.18.2, a missing authorization check in the Space member management controller allowed any authenticated user to trigger the removal of all members from any Space, regardless of their own role or membership in that Space. Versions 1.13.0 through 1.18.2 are affected. The vulnerability has been patched in version 1.18.3, and all users are encouraged to upgrade to this version or later immediately. No known workaround is available.7h
