What is CVE-2026-44654?

In LibreChat up to version 0.8.3, a vulnerability allows shared-agent editors to delete file records globally via the DELETE /api/files endpoint. This action disrupts private agents managed by the file owner, leading to stale file_id references that can cause functionality failures without alerting the owner. This violation of integrity between agents highlights the risk of editing access affecting multiple agents inappropriately. Users are advised to upgrade to version 0.8.4, which includes a necessary patch for this issue.
