Only the docker image with the latest version of QGIS is supported with security updates.
To report a vulnerability in the latest docker image, email the maintainer [email protected].
Vulnerabilities in docker images with prior versions of QGIS are not fixed.
Whenever a new version of QGIS is released, the previous version's docker image is rebuilt once again and then frozen.
Docker images may be rebuilt or extended if they fail to start or have runtime issues.
