Duplicate Advisory: Unfurl's unbounded zlib decompression allows decompression bomb DoS
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-h5qv-qjv4-pc5m. This link is maintained to preserve external references.
Original Description
Unfurl before 2026.04 contains an unbounded zlib decompression vulnerability in parse_compressed.py that allows remote attackers to cause denial of service. Attackers can submit highly compressed payloads via URL parameters to the /json/visjs endpoint that expand to gigabytes, exhausting server memory and crashing the service.
