# CallBackery for Perl: restored backup runs arbitrary OS commands

CallBackery versions before 0.62.0 pass the database dump in a configuration backup to the sqlite3 command-line shell during restore. A dump line starting with a dot, such as .shell or .system, runs an operating system command, and .load loads native code.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed CallBackery version; it is affected below `0.62.0`.
- Look for a restore feature that accepts backup files (restoreConfigBlob) in the deployed application.

## Fix

- CallBackery for Perl: `0.62.0`

## Timeline

- 2026-10-30T13:30:27+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118992

## From the sources

CallBackery versions before 0.62.0 for Perl allow OS command execution via sqlite3 shell commands in a restored configuration backup.

restoreConfigBlob() feeds the database dump in a backup to the sqlite3 command-line shell. The shell runs lines starting with a dot as its own commands, so .shell or .system in the dump runs an OS command and .load loads native code.

Anyone who can supply a backup to be restored can run arbitrary commands as the application user.
