"The version of pgAdmin installed on the remote host is prior to 9.12. It is, therefore, affected by 
command execution vulnerability:

  - pgAdmin versions prior to 9.12 are affected by a Restore restriction bypass via key disclosure 
    vulnerability that occurs when running in server mode and performing restores from PLAIN-format dump 
    files. An attacker with access to the pgAdmin web interface can observe an active restore operation, 
    extract the `\restrict` key in real time, and race the restore process by overwriting the restore script 
    with a payload that re-enables meta-commands using `\unrestrict <key>`. This results in reliable command 
    execution on the pgAdmin host during the restore operation. (CVE-2026-1707)

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