Harbor vs MISP: at a glance
What is Harbor?
Harbor's patch train is now mostly about undoing regressions from its own security hardening.
Harbor is shipping patch candidates on both the 2.14 and 2.15 lines. The 2.15.3 batch tightened security with manifest upload size limits, registry ping URL constraints, a fix for robot-name proxy-cache poisoning, and CSV formula neutralization. The 2.15.4 and 2.14.6 candidates then roll back defaults that broke existing setups, re-allowing webhooks to private networks and legacy signer pulls.
What is MISP?
MISP 2.5.50 deletes legacy discussions, templates and allowedlists as security fixes keep coming.
MISP is deep in a security-remediation cycle: 2.5.46, 2.5.47, 2.5.48 and now 2.5.50 each ship externally reported fixes, and 2.4.221 backported 57 of them to the EOL branch. 2.5.47 added PostgreSQL support and a first AI-assisted analysis integration. 2.5.50 moves Redis host settings to CLI-only and closes event-index and object-search information leaks. It also starts deleting legacy features outright.

Harbor
5.0INFRA · APIS
Harbor's patch train is now mostly about undoing regressions from its own security hardening.
◆ Current state
Harbor is shipping patch candidates on both the 2.14 and 2.15 lines. The 2.15.3 batch tightened security with manifest upload size limits, registry ping URL constraints, a fix for robot-name proxy-cache poisoning, and CSV formula neutralization. The 2.15.4 and 2.14.6 candidates then roll back defaults that broke existing setups, re-allowing webhooks to private networks and legacy signer pulls.
◆ Where it's heading
The registry is hardening its attack surface and paying for it in compatibility: stricter defaults landed, users hit regressions, and maintainers are now exposing switches in harbor.yml and restoring the permissive behavior. Earlier in the cycle, 2.15.2 swapped Redis for Valkey as the cache backend, a quiet infrastructure decision that now applies to every new install.
◆ Prediction
Expect 2.15.4 and 2.14.6 to reach GA with these regression fixes, and future security changes to ship as opt-in configuration switches before they become defaults.
MISP
6.3INFRA · APIS
MISP 2.5.50 deletes legacy discussions, templates and allowedlists as security fixes keep coming.
◆ Current state
MISP is deep in a security-remediation cycle: 2.5.46, 2.5.47, 2.5.48 and now 2.5.50 each ship externally reported fixes, and 2.4.221 backported 57 of them to the EOL branch. 2.5.47 added PostgreSQL support and a first AI-assisted analysis integration. 2.5.50 moves Redis host settings to CLI-only and closes event-index and object-search information leaks. It also starts deleting legacy features outright.
◆ Where it's heading
The project is shifting from adding hardening patches to shrinking its attack surface. In 2.5.50, event discussions become analyst notes, legacy templates become event templates, and signature allowedlists become warninglists, with migrations and logged failures. Combined with the Overmind UI migration and the database abstraction, this looks like a deliberate cleanup of the 2.5 codebase.
◆ Prediction
Expect further legacy features to be migrated and removed in the next releases, alongside more advisories from the ongoing review. Admins with workflows on the removed discussion trigger will need to adapt.
