    Feedgen Vulnerable to XML Denial of Service Attacks

    CVE-2020-5227 · GHSA-g8q7-xv52-hf9f

    Affected
    • PyPI feedgen < 0.9.0

    Issue
    Impact The feedgen library allows supplying XML as content for some of the available fields. This XML will be parsed and integrated into the existing XML tree. During this process, feedgen is vulnerable to XML Denial of Service Attacks (e.g. XML Bomb). This becomes a concern in particular if feedgen is used to include content from untrused sources and if XML (including XHTML) is directly included instead of providing plain tex content only. Patches This problem has been fixed in feedgen 0.9.0 which disallows XML entity expansion and external resources. Workarounds Updating is strongly recommended and should not be problematic. Nevertheless, as a workaround, avoid providing XML directly to feedgen or ensure that no entity expansion is part of the XML.

    Recommended action: Upgrade to 0.9.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
