Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Coraza v3 versions from 3.0.0 before 3.8.1 are vulnerable in the JSON body processor. An unauthenticated attacker who can send a request body with deeply nested JSON, within the default argument limit and recommended body size, can crash the whole host process with an unrecoverable stack overflow. Upgrade to Coraza 3.8.1, which is the listed fixed version. The source gives no workaround.
