From 3.0.0 until 3.8.1, Coraza silently drops arguments after SecArgumentsLimit in internal/corazawaf/transaction.go, while internal/bodyprocessors/urlencoded.go writes ARGS_POST without enforcing the cap. The flaw is triggered when an unauthenticated attacker sends more arguments than SecArgumentsLimit or supplies bodies that expand beyond the configured argument and flattening budgets. An unauthenticated attacker can flood requests with arguments so excess values are silently omitted from ARGS, ARGS_GET, ARGS_NAMES, ARGS_GET_NAMES, ARGS_POST, or ARGS_PATH before security rules inspect them; affected urlencoded and JSON processing can also consume excessive memory. The omission can bypass WAF rules protecting the downstream application, and unbounded or amplified argument processing can cause memory consumption and service degradation. This issue is fixed in version 3.8.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L","score":7.2},"cwes":["CWE-693","CWE-770"],"references":["https://github.com/corazawaf/coraza/commit/146c2f79f39ad16f13787e7d67ad400f8d8cb9a3","https://github.com/corazawaf/coraza/commit/b98359bb7e7606c95100dcc7ad490d2d624e6dea","https://github.com/corazawaf/coraza/releases/tag/v3.8.1","https://github.com/corazawaf/coraza/security/advisories/GHSA-6r3q-mjv7-xr8m","https://github.com/corazawaf/coraza/security/advisories/GHSA-6r3q-mjv7-xr8m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-41510","score":0.00378,"percentile":0.31478,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6r3q-mjv7-xr8m","url":"https://osv.dev/vulnerability/GHSA-6r3q-mjv7-xr8m","summary":"Coraza: Silent argument drop at ArgumentLimit allows bypass of ARGS-targeted rules via parameter flooding","modified":"2026-10-20T00:56:00.262914145Z","packages":[{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3","ranges":[">=3.0.0 <3.8.1"],"fixed":["3.8.1"]}]},{"id":"GO-2026-6668","url":"https://osv.dev/vulnerability/GO-2026-6668","summary":"Coraza: Silent argument drop at ArgumentLimit allows bypass of ARGS-targeted rules via parameter flooding in github.com/corazawaf/coraza","modified":"2026-10-20T00:45:10.146773404Z","packages":[{"ecosystem":"Go","name":"github.com/corazawaf/coraza","purl":"pkg:golang/github.com/corazawaf/coraza","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v2","purl":"pkg:golang/github.com/corazawaf/coraza/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3","ranges":[">=3.0.0 <3.8.1"],"fixed":["3.8.1"]}]}],"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).
