What is CommaFeed?

After a summer of security patches, CommaFeed 7.4 moves feed fetching to HTTP/2.

CommaFeed's 7.x line spent July and August on security fixes, one per patch release: an image-proxy SSRF, javascript: URLs filtered at parse time, local address blocking on by default, Host header injection in password recovery, and a cross-user disclosure via starring and tagging. Version 7.4.0 on October 19 turned back to fetching, with HTTP/2, more default headers so fewer servers reject it, and tighter iframe sandboxing; 7.4.1 three days later fixed entries being marked read on scroll-back and added an HTTP/2 timeout.

What is SOGo?

SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.

SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

5.0

After a summer of security patches, CommaFeed 7.4 moves feed fetching to HTTP/2.

◆ Current state

CommaFeed's 7.x line spent July and August on security fixes, one per patch release: an image-proxy SSRF, javascript: URLs filtered at parse time, local address blocking on by default, Host header injection in password recovery, and a cross-user disclosure via starring and tagging. Version 7.4.0 on October 19 turned back to fetching, with HTTP/2, more default headers so fewer servers reject it, and tighter iframe sandboxing; 7.4.1 three days later fixed entries being marked read on scroll-back and added an HTTP/2 timeout.

◆ Where it's heading

With the security backlog cleared, releases are shifting to feed compatibility and reading behavior. The quick 7.4.1 follow-up suggests the HTTP/2 client is still settling.

◆ Prediction

Further 7.4.x patches for the HTTP/2 client are the likeliest next entries.

2.5

SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.

◆ Current state

SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

◆ Where it's heading

Fixes are increasingly arriving with secure defaults that break lax configurations, first password recovery URLs and then LDAP certificate checks. Feature work has been absent since 5.12.4 a year ago.

◆ Prediction

Further 5.12.x security releases are likely; operators should expect more defaults that require configuration changes.
