CVE-2026-107826 OWASP Coraza WAF: JSON body processor: argument-limit truncation reopens an unbounded-depth gjson.Valid stack overflow (process crash)

OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. 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...

CVE-2026-107826

The OWASP Coraza WAF library (versions 3.0.0 to 3.8.1 ) is vulnerable to a stack overflow due to how the readJSON function in internal/bodyprocessors/json.go handles argument limits.
