Hi,
The following vulnerability was published for jinja2.
CVE-2020-28493[0]:
| This affects the package jinja2 from 0.0.0 and before 2.11.3. The
| ReDOS vulnerability of the regex is mainly due to the sub-pattern
| [a-zA-Z0-9._-]+.[a-zA-Z0-9._-]+ This issue can be mitigated by
| Markdown to format user content instead of the urlize filter, or by
| implementing request timeouts and limiting process memory.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
