OTOBO 10.0.27 – Patch Level Release

More Security with Redis 8

• We are upgrading from Redis 6.0 to Redis 8 as the default caching module for Docker, since the older version is affected by a critical security vulnerability (CVE-2025-49844).

Benefit:
No additional configuration is required — OTOBO will now ship with Redis 8 by default.

Alternative:
Instead of updating OTOBO, you can simply set OTOBO_IMAGE_REDIS=redis:8-bookworm in your .env file in the otobo-docker directory, then run: docker-compose down; docker-compose up -d to switch the Redis image.
Also, you can completely disable Redis by commenting out the line $Self->{'Cache::Module'} = [...] in your Kernel/Config.pm.
