CVE-2019-19450

Ravi Prakash Giri discovered a remote code execution vulnerability via crafted XML document where <unichar code=' is followed by arbitrary Python code.

This issue is similar to CVE-2019-17626.

CVE-2020-28463

Karan Bamal discovered a Server-side Request Forgery (SSRF) vulnerability via <img> tags. New settings trustedSchemes and trustedHosts have been added as part of the fix/mitigation: they can be used to specify an explicit allowlist for remote sources.

For Debian 10 buster, these problems have been fixed in version 3.5.13-1+deb10u2.

We recommend that you upgrade your python-reportlab packages.

For the detailed security status of python-reportlab please refer to its security tracker page at: [link moved to references]
