SOGo vs SiYuan: 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 SiYuan?
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
SOGo vs SiYuan: 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.
SiYuan
5.0COLLAB
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
◆ Current state
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
◆ Where it's heading
SiYuan works in fast public cycles, with the next version's alphas starting as soon as the last one stabilises. 3.8.11 is about polish and editing depth: mind maps, databases and the new Markdown editor all get more control.
◆ Prediction
Expect more 3.8.11 alphas, then betas and release candidates with the same list, following the 3.8.10 pattern.
