Bandit versions lower than 1.1.0 do not escape HTML in issue reports
---
### Summary ###
Bandit versions lower than 1.1.0 have a bug in the HTML report formatter
that does not escape HTML in issue context snippets. This could lead to
an XSS if HTML reports are hosted as part of a CI pipeline.
### Affected Services / Software ###
Bandit: < 1.1.0
### Discussion ###
Bandit versions lower than 1.1.0 have a bug in the HTML report formatter
that does not escape HTML in issue context snippets. This could lead to
an XSS attack if HTML reports are hosted as part of a CI pipeline
because HTML in the source code would be copied verbatim into the report.
For example:
import subprocess
subprocess.Popen("<script>alert(1)</script>", shell=True)
Will cause "<script>alert(1)</script>" to be inserted into the HTML
report. This issue could allow for arbitrary code injection into CI/CD
pipelines that feature accessible HTML reports generated from Bandit runs.
### Recommended Actions ###
Update bandit to version 1.1.0 or greater.
