CVE-2025-30153Public exploitNetwork attack vector

Server crash via unbounded ZIP decompression

Published Mar 19, 2025 · Updated Mar 19, 2025

Resource exhaustion in getkin kin-openapi before 0.131.0 allows remote attackers to crash servers via crafted multipart ZIP uploads. The automatically registered ZipFileBodyDecoder expands archive entries into memory without enforcing a decompressed-size limit. Exposure requires request validation against a multipart/form-data schema that permits ZIP uploads; successful requests exhaust memory and crash or degrade the hosting server.
