HedgeDoc vs SOGo: at a glance
What is HedgeDoc?
HedgeDoc 1.12.1 fixes seven advisories, then gets pulled for a PostgreSQL migration bug
HedgeDoc 1.12.1 fixed seven security advisories, including an impersonation attack when two auth providers return the same profile id, a timing leak that revealed registered emails, and unescaped iframes in slides. It was pulled within minutes because a profile provider migration failed on PostgreSQL, and 1.12.2 replaces it. The release also lets OAuth2 and OIDC providers supply profile photos and updates mermaid to 11.17.
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.

HedgeDoc 1.12.1 fixes seven advisories, then gets pulled for a PostgreSQL migration bug
◆ Current state
HedgeDoc 1.12.1 fixed seven security advisories, including an impersonation attack when two auth providers return the same profile id, a timing leak that revealed registered emails, and unescaped iframes in slides. It was pulled within minutes because a profile provider migration failed on PostgreSQL, and 1.12.2 replaces it. The release also lets OAuth2 and OIDC providers supply profile photos and updates mermaid to 11.17.
◆ Where it's heading
The 1.x line remains driven by security response, with advisory batches arriving every one to three months. This release adds a schema migration, and the immediate PostgreSQL breakage shows the risk of mixing data changes into security patches. Small auth and rendering features keep arriving alongside the fixes.
◆ Prediction
More advisory batches on the 1.12.x line are likely, given the pattern; the entries do not show when the next major line will replace 1.x.
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.
