Hi,
there have been new versions for Roundcube webmail available since 4 weeks. These versions fix 2 CVE that were found in the versions we are running in Mail-in-a-box. There is a PR in Github available for 3 weeks: [security] Update roundcube to 1.6.13 by kiekerjan · Pull Request #2554 · mail-in-a-box/mailinabox · GitHub
Is somebody with commit permissions working on integrating this PR and release a new version of mail-in-a-box? If not, I will start investigating how I can disable Roundcube altogether.
regards
Lars
