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 NGINX?

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

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.

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

◆ Current state

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

◆ Where it's heading

HTTP/3 has needed fixes in each of the last three mainline releases, two of them CVEs. Mainline is adding features and removing legacy code at the same time, while stable gets the CVE backports.

◆ Prediction

More HTTP/3 fixes on both lines are likely; on mainline, follow-up work on the control API and JSON module is the next feature thread to watch.
