CVE-2026-44981

CrowdSec offers crowdsourced protection against malicious IPs. From 1.7.0 until 1.7.8, the LAPI router used gin-contrib/gzip with DefaultDecompressHandle globally in pkg/apiserver/controllers/controller.go, causing /v1/watchers and /v1/watchers/login to decompress unauthenticated gzip-compressed JSON request bodies without enforcing a maximum decompressed size and allowing excessive heap allocation that can make LAPI unreachable. This issue is fixed in version 1.7.8.
