What is Casdoor?

Casdoor is spending its release cadence moving auth checks from the client to the server

Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.

What is CrowdSec?

CrowdSec's WAF is growing a bot-detection challenge — log analysis meets active interception.

The feed carries only release candidates, roughly one every two to three months, and the WAF has been the centre of gravity across all of them: OpenAPI schema validation, request body size limits, arbitrary AND/OR mixing in rule conditions, more Coraza transformations exposed, RE2 enabled by default on Linux. The 1.8.0 candidate breaks that pattern by adding challenge-and-fingerprint bot detection, serving an interstitial page and evaluating the result against configured rules. The same candidate adds a dedicated Kubernetes datasource that reads logs from the apiserver directly, and HTTP helpers so parsers and scenarios can query external services. Two earlier candidates in the window are pure refactoring with no user-visible change.

Casdoor is spending its release cadence moving auth checks from the client to the server

◆ Current state

Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.

◆ Where it's heading

Read together, these commits describe one job: closing the gap between what the console enforces and what the backend enforces. Several of them move a check that previously lived in the UI into the server, which is the work of a project being deployed into environments that audit it. New authentication providers and integrations have thinned relative to this hardening pass.

◆ Prediction

The next releases most likely continue the same sweep - remaining endpoints where an admin or user request is trusted more than the server verifies - rather than adding a new identity provider.

CrowdSec's WAF is growing a bot-detection challenge — log analysis meets active interception.

◆ Current state

The feed carries only release candidates, roughly one every two to three months, and the WAF has been the centre of gravity across all of them: OpenAPI schema validation, request body size limits, arbitrary AND/OR mixing in rule conditions, more Coraza transformations exposed, RE2 enabled by default on Linux. The 1.8.0 candidate breaks that pattern by adding challenge-and-fingerprint bot detection, serving an interstitial page and evaluating the result against configured rules. The same candidate adds a dedicated Kubernetes datasource that reads logs from the apiserver directly, and HTTP helpers so parsers and scenarios can query external services. Two earlier candidates in the window are pure refactoring with no user-visible change.

◆ Where it's heading

CrowdSec started as a log-reading detection engine that handed decisions to external bouncers, and the WAF work has been steadily moving it into the request path. Bot detection completes that move: the product now generates its own signal by interrogating the client rather than only inferring from logs. The Kubernetes datasource and the expression-language HTTP helpers point the same way — fewer intermediaries between CrowdSec and both the telemetry and the enforcement point.

◆ Prediction

Expect the fingerprinting rules to become a shared, community-curated resource in the same way detection scenarios already are, since that is the pattern this project applies to every new signal it collects.
