From 3.0.0 until 3.8.1, readJSON in internal/bodyprocessors/json.go can stop its bounded flattening walk after reaching SecArgumentsLimit or the byte budget and then call gjson.Valid on the complete raw body. An unauthenticated attacker can submit shallow values followed by an extremely deeply nested JSON tail that was not visited by the bounded walk, causing gjson.Valid to recurse without a depth bound and terminate the hosting process with an unrecoverable fatal stack overflow. The ProcessRequest and ProcessResponse JSON paths share the affected readJSON validation flow, and the payload can remain within recommended body-size and argument-count limits. This issue is fixed in version 3.8.1.","state":0,"publishedAt":"2026-10-09T18:17:04.673+00:00","modifiedAt":"2026-10-16T17:16:41.3+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/corazawaf/coraza/commit/814e1898e083d2ff2ceb644382d0da17e930f93f","https://github.com/corazawaf/coraza/releases/tag/v3.8.1","https://github.com/corazawaf/coraza/security/advisories/GHSA-6gcq-wc29-5xf2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107826","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-674"],"productCriteria":[],"sourceDates":{"published":"2026-10-09T18:17:04.673","lastModified":"2026-10-16T17:16:41.300"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
