What is Element?

Element Web is opening an extension surface while rebuilding its timeline underneath.

Element Web ships on a steady RC-then-final cadence, and two threads dominate the last month. The first is presence: custom user status has landed piece by piece across releases — member list, room header, autocomplete, room summary — and now includes on-a-call state users can set and clear themselves. The second is a module system, which reached v1.0.0 across four separate modules in early August and keeps gaining API surface, most recently storage helpers plus a dedicated modules docker image.

What is Roundcube?

Roundcube is shipping matched security pairs across 1.7 and 1.6 LTS, roughly monthly.

Every release in this window is a security update, and they arrive in matched pairs — the same fix set landed on the 1.7 stable branch and backported to the 1.6 LTS branch minutes apart. The August pair closes eleven reported issues, including remote code execution through the markasjunk plugin's cmd_learn driver, IMAP command injection via LITERAL+ byte-count desynchronization, LDAP filter injection through unescaped substitution in search_filter, arbitrary Sieve script injection past managesieve_disabled_actions, multiple SSRF filter bypasses, and stored XSS. The June and July pairs follow the same structure with different findings.

Element vs Roundcube: editorial side-by-side

5.0

Element Web is opening an extension surface while rebuilding its timeline underneath.

◆ Current state

Element Web ships on a steady RC-then-final cadence, and two threads dominate the last month. The first is presence: custom user status has landed piece by piece across releases — member list, room header, autocomplete, room summary — and now includes on-a-call state users can set and clear themselves. The second is a module system, which reached v1.0.0 across four separate modules in early August and keeps gaining API surface, most recently storage helpers plus a dedicated modules docker image.

◆ Where it's heading

The module work is the more consequential of the two. Banner, Widget Toggles, Widget Lifecycle and Restricted Guests all hit v1.0.0 on the same day, and the releases since have been about giving those modules more to reach — settings access, storage helpers, a deployable image. That is infrastructure for operators to extend the client rather than fork it. Alongside it, Timeline MVVM has begun as a shared TimelineView, the opening step of a longer architectural refactor that individual release notes will keep understating.

◆ Prediction

Expect Timeline MVVM to arrive in numbered stages across coming releases, and the Module API to keep widening past storage and settings as the four v1.0.0 modules run into what they cannot yet reach.

R5.0

Roundcube is shipping matched security pairs across 1.7 and 1.6 LTS, roughly monthly.

◆ Current state

Every release in this window is a security update, and they arrive in matched pairs — the same fix set landed on the 1.7 stable branch and backported to the 1.6 LTS branch minutes apart. The August pair closes eleven reported issues, including remote code execution through the markasjunk plugin's cmd_learn driver, IMAP command injection via LITERAL+ byte-count desynchronization, LDAP filter injection through unescaped substitution in search_filter, arbitrary Sieve script injection past managesieve_disabled_actions, multiple SSRF filter bypasses, and stored XSS. The June and July pairs follow the same structure with different findings.

◆ Where it's heading

Roundcube is absorbing sustained external security-research attention and has settled into a repeatable response cadence: fix, pair the branches, ship. The recurring categories are telling — HTML and CSS sanitizer bypasses via SVG attributes, SSRF filters defeated by address-space and hostname tricks, and injection through plugin drivers — which means the same attack surfaces keep yielding new variants rather than being closed once. The 1.5 branch received its last pair in March; since 1.7.0 arrived in May, maintenance has narrowed to two branches instead of three.

◆ Prediction

Expect the next release to be another 1.7/1.6 security pair rather than a feature drop, and to include further sanitizer or URL-fetch bypass fixes, since those two categories have recurred in every pair in this window.
