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. When the bounded flattening walk reaches the SecArgumentsLimit or byte budget, it may still call gjson.Valid on th...

CVE-2026-107833: Uncontrolled Recursion

OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. From 3.0.0 until 3.8.0, ProcessResponse in internal/bodyprocessors/json.go passes the ignoreJSONRecursionLimit value of -1 to readJSON, while the recursive guard only stops at zero. A network attacker who can...

GHSA-3C6W-J9XM-8H2H 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...
