CVE-2026-44981: Crowdsecurity Crowdsec

High severity, CVSS 8.2. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

  • Crowdsecurity Crowdsec: from 1.7.0, before 1.7.8 (fixed in 1.7.8)
