What is Prowlarr?

Prowlarr adds Trusted Networks and host validation, then moves to 2.7

Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.

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.

Prowlarr vs SOGo: editorial side-by-side

P
Prowlarr
COLLAB
5.0

Prowlarr adds Trusted Networks and host validation, then moves to 2.7

◆ Current state

Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.

◆ Where it's heading

Security settings that limit which hosts and networks can reach the app are the main thread since September, rolled out in step with Lidarr. Indexer definitions keep getting small compatibility fixes.

◆ Prediction

More indexer-level fixes and Allowed Hosts follow-ups are likely in 2.7 patches.

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.
