    CVE-2026-40036 (GCVE-0-2026-40036)

    Vulnerability from cvelistv5 – Published: 2026-04-08 21:35 – Updated: 2026-05-14 16:05
    VLAI
    Title
    Unfurl < 2026.04 - Denial of Service via Unbounded zlib Decompression
    Summary
    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.

    CVE-2026-40035 (GCVE-0-2026-40035)

    Vulnerability from cvelistv5 – Published: 2026-04-08 21:35 – Updated: 2026-05-08 14:07

    Title
    Unfurl - Werkzeug Debugger Exposure via String Config Parsing
    Summary
    Unfurl through 2025.08 contains an improper input validation vulnerability in config parsing that enables Flask debug mode by default. The debug configuration value is read as a string and passed directly to app.run(), causing any non-empty string to evaluate truthy, allowing attackers to access the Werkzeug debugger and disclose sensitive information or achieve remote code execution.
