pgAdmin versions up to 9.10 are affected by a Remote Code Execution (RCE) vulnerability that occurs when running in server mode and performing restores from PLAIN-format dump files. This issue allows attackers to inject and execute arbitrary commands on the server hosting pgAdmin, posing a critical risk to the integrity and security of the database management system and underlying data.

Affected: PyPI: pgadmin4

The PLAIN restore meta-command filter introduced in pgAdmin as part of the fix for CVE-2025-12762 does not detect meta-commands when a SQL file begins with a UTF-8 Byte Order Mark (EF BB BF) or other special byte sequences. The implemented filter uses the function `has_meta_commands()`, which scans raw bytes using a regular expression. The regex does not treat the bytes as ignorable, so meta-commands such as `\\!` remain undetected. When pgAdmin invokes psql with --file, psql strips the bytes and executes the command. This can result in remote command execution during a restore operation.
