Description

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability in the MobileFileDownload route that allows unauthenticated attackers to download arbitrary files by computing an md5(filename) token instead of passing a proper authorization check. Attackers can guess or determine file names to generate the corresponding md5 token and retrieve protected files without authorization, leading to unauthorized information disclosure.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-63163 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
