On a miss it keeps everything and searches again from the start when the next chunk arrives. A body with no boundary, or with a delimiter followed by neither CRLF nor \"--\", is therefore rescanned on every chunk, taking time quadratic in its size.\n\nA remote attacker can exhaust worker CPU with a few such requests.\n\n## Affected\n\n- `HTTP-Body < 1.23_01`\n\n## Remediation\n\nUpgrade to HTTP-Body 1.23_01 or later.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
