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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":null,"cwes":["CWE-409"],"references":["https://github.com/crowdsecurity/crowdsec/commit/54a0dfe6c16b7687b0da6634e0b19ef0f5d9bb30","https://github.com/crowdsecurity/crowdsec/commit/56d0d6915f7f25941dc5b4f484028646f6601a37","https://github.com/crowdsecurity/crowdsec/security/advisories/GHSA-273h-gvwr-c3qj"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-44981","score":0.00507,"percentile":0.42953,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-273h-gvwr-c3qj","url":"https://osv.dev/vulnerability/GHSA-273h-gvwr-c3qj","summary":"CrowdSec LAPI: Denial of Service via Unbounded Gzip Decompression","modified":"2026-06-17T00:26:11.609038661Z","packages":[{"ecosystem":"Go","name":"github.com/crowdsecurity/crowdsec","purl":"pkg:golang/github.com/crowdsecurity/crowdsec","ranges":[">=1.7.0 <1.7.8"],"fixed":["1.7.8"]}]},{"id":"GO-2026-5041","url":"https://osv.dev/vulnerability/GO-2026-5041","summary":"CrowdSec LAPI: Denial of Service via Unbounded Gzip Decompression in github.com/crowdsecurity/crowdsec","modified":"2026-06-17T00:15:12.870581820Z","packages":[{"ecosystem":"Go","name":"github.com/crowdsecurity/crowdsec","purl":"pkg:golang/github.com/crowdsecurity/crowdsec","ranges":[">=1.7.0 <1.7.8"],"fixed":["1.7.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
