Roundcube vs VerneMQ
A side-by-side editorial comparison of Roundcube and VerneMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Roundcube vs VerneMQ: at a glance
What is Roundcube?
Roundcube's October release patches 13 more holes on both branches at once.
Roundcube shipped 1.7.5 and 1.6.20 on 19 October, again as a matched pair, fixing IMAP command injection via the _uid parameter, mail header injection in bounce and reply paths, a session object-injection primitive, ImageMagick limits bypasses, an SSRF filter bypass via NAT64 and several remote-content blocking bypasses. It is the fifth paired security release since June.
What is VerneMQ?
VerneMQ follows its year-in-the-making 2.2.0 with a quick round of subscription fixes.
VerneMQ releases infrequently; 2.2.0 on August 9 gathered about a year of cluster and connection work, including a socket-counting fix under rapid reconnects and faster inter-node readiness checks. 2.2.1 on October 16 followed with fixes for stale shared subscriptions after trie restarts, enforcement of non-zero message ids, and new webhook connect options.
Roundcube vs VerneMQ: editorial side-by-side
Roundcube
5.0COMMS
Roundcube's October release patches 13 more holes on both branches at once.
◆ Current state
Roundcube shipped 1.7.5 and 1.6.20 on 19 October, again as a matched pair, fixing IMAP command injection via the _uid parameter, mail header injection in bounce and reply paths, a session object-injection primitive, ImageMagick limits bypasses, an SSRF filter bypass via NAT64 and several remote-content blocking bypasses. It is the fifth paired security release since June.
◆ Where it's heading
Monthly security releases on both the 1.7 and LTS 1.6 lines have become the product's main output, driven by outside researchers. Several fixes revisit earlier ones, such as CSS-escape blocking bypasses fixed 'again', which suggests the content-sanitising code is still being mapped.
◆ Prediction
Another paired 1.7.x and 1.6.x security release in about a month is the pattern; feature work isn't visible in these entries.
VerneMQ
2.5COMMS
VerneMQ follows its year-in-the-making 2.2.0 with a quick round of subscription fixes.
◆ Current state
VerneMQ releases infrequently; 2.2.0 on August 9 gathered about a year of cluster and connection work, including a socket-counting fix under rapid reconnects and faster inter-node readiness checks. 2.2.1 on October 16 followed with fixes for stale shared subscriptions after trie restarts, enforcement of non-zero message ids, and new webhook connect options.
◆ Where it's heading
Two months between 2.2.0 and 2.2.1 is quick for this project, which suggests 2.2 is getting active maintenance. The work stays inside the broker: subscriptions, clustering and protocol correctness rather than new features.
◆ Prediction
Further 2.2.x patches are more likely than a new minor; the feed gives no sign of 2.3 work.
