The analysis of the security patch for CVE-2025-12762 in pgAdmin4 reveals a Remote Code Execution vulnerability within the restore functionality. The commit 1d397395f75320ca1d4ed5e9ca721c603415e836 directly addresses this issue. The core of the vulnerability lies in the use_sql_utility function located in web/pgadmin/tools/restore/__init__.py. This function is invoked when a user performs a restore from a PLAIN-format SQL dump file. Before the patch, this function did not inspect the content of the dump file for psql meta-commands. This allowed an attacker to craft a malicious SQL file containing commands such as \! which psql interprets as a directive to execute a shell command. The patch rectifies this by introducing a new function, has_meta_commands, which scans the file for such commands. The use_sql_utility function is modified to use this check and abort the restore operation if any meta-commands are detected. Therefore, the use_sql_utility function is the specific location of the vulnerability, as it was the function that failed to properly sanitize its input before passing it to an external command-line utility.
