Auth bypass in Solidtime
CVE-2026-42279
solidtime is an open-source time-tracking app. In version 0.12.0, the PUT /api/v1/organizations/{organization}/time-entries/{timeEntry} API accepts a route-bound timeEntry from another organization when the caller has time-entries:update:all in the URL organization, allowing a known foreign time-entry UUID to be modified and rebound to objects in the caller's organization. This issue has been patched in version 0.12.1.
