Roundcube vs Rocket.Chat: at a glance
What is Roundcube?
Roundcube patches its Sieve filters and CSRF checks in a sixth paired security release
Roundcube shipped 1.7.6 and 1.6.21 on 9 November, three weeks after 1.7.5 and 1.6.20, again as an identical security pair. This round centres on the managesieve filter plugin (two script-injection paths and destructive actions triggerable cross-site via GET), plus CSRF bypasses, an open redirect, an SSRF bypass via nip.io and sslip.io hostnames and a disabled_actions bypass.
What is Rocket.Chat?
Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.
The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

Roundcube
5.0COMMS
Roundcube patches its Sieve filters and CSRF checks in a sixth paired security release
◆ Current state
Roundcube shipped 1.7.6 and 1.6.21 on 9 November, three weeks after 1.7.5 and 1.6.20, again as an identical security pair. This round centres on the managesieve filter plugin (two script-injection paths and destructive actions triggerable cross-site via GET), plus CSRF bypasses, an open redirect, an SSRF bypass via nip.io and sslip.io hostnames and a disabled_actions bypass.
◆ Where it's heading
Security releases now arrive every three to five weeks, each with a dozen or more externally reported fixes, and the same research group is behind many of them. The project is in a sustained audit phase, and both branches move together every time.
◆ Prediction
Another paired 1.7.x and 1.6.x security release within about a month is the most likely next entry, given the cadence since June.
Rocket.Chat
6.3COMMS
Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.
◆ Current state
The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.
◆ Where it's heading
9.0 is in stabilization: each candidate is smaller than the last, and the load fixes are being carried to the LTS line rather than held for the major. Native LiveKit video is being promoted step by step, from alpha to beta and now as the named default provider option.
◆ Prediction
With rc.7 down to a handful of fixes, 9.0.0 GA is the next likely release, followed by further 8.9.x LTS patches carrying the same fixes.
