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 Stoat?

Stoat moves to release candidates and Gerrit, and gives server admins more control.

Stoat's 0.16.0 release candidates add server controls: invites with expiry and use limits, permission to block external emojis, and bot roles that grant permissions when a bot joins. The team is also piloting Gerrit as its main source control and will now ship release candidates and backports.

Roundcube vs Stoat: editorial side-by-side

R5.0

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.

Stoat
COMMS
5.0

Stoat moves to release candidates and Gerrit, and gives server admins more control.

◆ Current state

Stoat's 0.16.0 release candidates add server controls: invites with expiry and use limits, permission to block external emojis, and bot roles that grant permissions when a bot joins. The team is also piloting Gerrit as its main source control and will now ship release candidates and backports.

◆ Where it's heading

The feature list is about moderation and bot management for server owners, and rc.1 adds OpenTelemetry tracing for the file service. The process change toward RCs and backports suggests the team wants steadier releases for self-hosters.

◆ Prediction

A final 0.16.0 should follow the two RCs; the entries do not say when.
