CVE-2026-107826
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. When the bounded flattening walk reaches the SecArgumentsLimit or byte budget, it may still call gjson.Valid on th...
CVE-2026-107826: Uncontrolled Recursion
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.

Coraza: Unbounded recursion in JSON response body processor causes CPU exhaustion
Summary The JSON response body processor parses response bodies with no recursion limit. ProcessResponse calls readJSONss, ignoreJSONRecursionLimit, and that constant is -1. The guard in readItems only fires on == 0, so counting down from -1 -2, -3, ... never reaches it. The guard is effectively...
