common/snapshots.py in Back In Time (aka backintime) 0.9.26 changes certain permissions to 0777 before deleting the files in an old backup snapshot, which allows local users to obtain sensitive information by reading these files, or interfere with backup integrity by modifying files that are shared across snapshots.

Security readout for executives and security teams

Back In Time 0.9.26 could briefly make old backup snapshot files world-readable and world-writable while deleting them. On shared systems, a local user might read sensitive backup data or alter files shared between snapshots. This is not described as remote code execution. Exposure is most likely on Linux systems running Back In Time/backintime 0.9.26, especially multi-user hosts or systems where backup snapshots are accessible to local untrusted users. Treat this as moderate priority. It is local rather than internet-facing, but it can expose sensitive backup data and undermine backup trust on shared systems. Mitigation focus: Inventory systems running Back In Time/backintime, especially version 0.9.26.; Check Debian, Fedora, Ubuntu, Gentoo, or Red Hat guidance for fixed packages.; Update affected packages through the relevant distribution channel..
