SOGo vs Double: 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 Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
SOGo vs Double: 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.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
