SOGo vs Interact: at a glance
What is SOGo?
SOGo's 5.12.13 fixes its largest batch of vulnerabilities yet, some critical.
SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made almost every 2026 release about security. v5.12.13 on 4 November fixes two SQL injections, a buffer overflow, an LDAP filter injection, path traversal, an impersonation flaw and several unsafe HTML elements, affecting all previous versions. It follows 5.12.11's password reset poisoning fix and 5.12.12's switch to verifying LDAP TLS certificates by default.
What is Interact?
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
Interact's October feed is led by Interact MCP, which brings the intranet into AI assistants people already use, with read and write access under each person's permissions. Its security team joined Anthropic's Cyber Verification Program and is testing its own platform with Claude Mythos 5.1, and Cyber Essentials certification now covers Interact and Sideways 6. The rest of the month is buyer guides, award news and thought leadership.
SOGo vs Interact: editorial side-by-side
SOGo
5.0COLLAB
SOGo's 5.12.13 fixes its largest batch of vulnerabilities yet, some critical.
◆ Current state
SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made almost every 2026 release about security. v5.12.13 on 4 November fixes two SQL injections, a buffer overflow, an LDAP filter injection, path traversal, an impersonation flaw and several unsafe HTML elements, affecting all previous versions. It follows 5.12.11's password reset poisoning fix and 5.12.12's switch to verifying LDAP TLS certificates by default.
◆ Where it's heading
Outside researchers and coordinators such as VulnCheck are now reporting issues in batches, and each release closes several at once. The fixes are moving from individual XSS paths toward input handling across SQL, LDAP and file paths, which points to a broader audit of the codebase rather than one-off patches.
◆ Prediction
Expect CVE IDs for the 5.12.13 fixes to be published and further 5.12.x security releases at a roughly monthly pace; the entries show no sign of a feature release.
Interact
5.0COLLAB
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
◆ Current state
Interact's October feed is led by Interact MCP, which brings the intranet into AI assistants people already use, with read and write access under each person's permissions. Its security team joined Anthropic's Cyber Verification Program and is testing its own platform with Claude Mythos 5.1, and Cyber Essentials certification now covers Interact and Sideways 6. The rest of the month is buyer guides, award news and thought leadership.
◆ Where it's heading
The Spring Action Agent work put agents inside the intranet; MCP moves the intranet out to wherever employees already work. That raises the stakes on trust, which is why the security items matter more than they would alone: a system holding company knowledge is being opened to more clients. The company's content messaging now describes the intranet as adaptive.
◆ Prediction
Expect Conductor and MCP connections to reach more business systems, following the Workday pattern from the Spring Launch. Further security attestations are also likely as AI access expands.
