What is CrowdSec?

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

What is Icinga?

Icinga 2 has now shipped security releases in July, August and October.

Icinga 2 patches security issues as simultaneous releases across its supported branches. On 28 October v2.16.6 and v2.15.7 fixed mail-flag injection in the default notification scripts plus several API issues. That follows the August pair closing a /v1/events permission bypass and a node-to-node memory exhaustion path, and the July trio covering 2.14, 2.15 and 2.16 with fixes for unauthenticated takeover and crash bugs.

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

◆ Current state

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

◆ Where it's heading

The WAF remains the center of gravity, and the direction is programmability. RateLimit, SkipProcessing and the fingerprinting hooks give rule authors primitives rather than fixed behavior. The LAPI changes point at larger deployments, where decision streaming puts load on the central API.

◆ Prediction

The final 1.8.2 is dated 26 October on GitHub, though it has not reached this feed yet. Whether fingerprint data ever joins the community blocklist remains unanswered in these notes.

Icinga 2 has now shipped security releases in July, August and October.

◆ Current state

Icinga 2 patches security issues as simultaneous releases across its supported branches. On 28 October v2.16.6 and v2.15.7 fixed mail-flag injection in the default notification scripts plus several API issues. That follows the August pair closing a /v1/events permission bypass and a node-to-node memory exhaustion path, and the July trio covering 2.14, 2.15 and 2.16 with fixes for unauthenticated takeover and crash bugs.

◆ Where it's heading

Three security rounds in four months point to a sustained audit of the API and cluster protocol, now reaching the shipped notification scripts. The 2.14 branch got the July fixes but no 2.14 release appears in the feed for August or October, which suggests its support is narrowing.

◆ Prediction

Further paired 2.16.x and 2.15.x security releases are likely while the audit continues; watch whether 2.14 gets the October fixes at all.
