CVE-2026-1253378.3 HIG—
——0Winter CMS is a content management system built on the Laravel PHP framework. Prior to 1.2.14, the ImportExportController behavior applies userHasAccess() only to the import() and export() page actions, while Backend\Classes\Controller::execAjaxHandlers() dispatches onImport(), onImportLoadForm(), onImportLoadColumnSampleForm(), onExport(), and onExportLoadForm() before those gated actions run, and the separately reachable download() action also lacks the granular export check. An authenticated backend user with a valid session and coarse access through $requiredPermissions, but without the configured import[permissions] or export[permissions], can use the import handlers to write or overwrite records and can use onExport() followed by download() to retrieve the complete dataset exposed by the export model. Controllers without granular permission keys are unaffected because userHasAccess() is intentionally default-permissive. This issue is fixed in version 1.2.14.3hCVE-2026-1208158.4 HIG—
——0An incorrect authorization check in the MongoDB Server authorization subsystem may allow an unauthenticated party with local host access to obtain administrative privileges on a database server that has authorization enabled. This may result in unintended access to stored data and credentials, unintended modification of data, and loss of availability of the server.3hCVE-2026-961627.8 HIG—

——0HarnessRouter is a self-hosted unified API for running agent harnesses with sessions, streaming, files, cancellation, and failure handling. Prior to 0.31.8, a console that is not in self-hosted mode attaches the server's internal key to requests carrying an Authorization header before validating the bearer, while the service-only PUT and GET /v1/orgs/{org}/connections/{name}, PUT /v1/orgs/{org}/policy/{backend}, and /internal/* routes trust that key and take the organization from the URL. In a multi-organization deployment, a remote caller can use a made-up bearer to rewrite another organization's provider connection to an attacker-controlled endpoint, causing later prompts to be disclosed and attacker-controlled responses to influence tasks. This issue is fixed in version 0.31.8.4hCVE-2026-1207827.8 HIG—
