Dfir Unfurl
Monthly
Unbounded zlib decompression in dfir-unfurl versions through 20250810 enables unauthenticated remote attackers to exhaust server memory via crafted compressed payloads submitted to the /json/visjs endpoint. Attackers can submit highly compressed data that expands to gigabytes when decompressed, crashing the service through resource exhaustion. The vulnerability affects the parse_compressed.py module and requires no authentication. No public exploit identified at time of analysis.
