multiple vulnerabilites.

  - A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability. A low privileged attacker with local access
    could potentially exploit this vulnerability, leading to code execution and possibly privilege escalation. (CVE-2025-22394)

  - A race condition vulnerability. A local malicious user could potentially exploit this vulnerability during
    installation, leading to arbitrary folder or file deletion (CVE-2025-21101)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
