[!WARNING] After upgrading to Flox 1.19.2, we recommend rebooting your system to ensure full remediation.

This release patches CVE-2026-111497, a vulnerability in the Brotli decompression library used by Flox's bundled Nix.

We are not currently aware of a direct exploit against Flox. The Brotli vulnerability could be chained with a compromise of other trusted infrastructure or a MITM attack. An attacker could serve malicious Brotli-compressed data via:

  • A Nix substituter.
  • An endpoint used to download a flake.
  • An endpoint used to download source for packages built from source.

This could potentially allow arbitrary code execution on the host running Flox.

[!NOTE] You can find the SHA256 checksums for Flox 1.19.2 and SHA512 checksums for Flox 1.19.2 online.
