Summary
Reflected cross-site scripting issue in Datasette
Details

Impact

The ?_trace=1 debugging feature in Datasette does not correctly escape generated HTML, resulting in a reflected cross-site scripting vulnerability.

This vulnerability is particularly relevant if your Datasette installation includes authenticated features using plugins such as datasette-auth-passwords as an attacker could use the vulnerability to access protected data.

Patches

Datasette 0.57 and 0.56.1 both include patches for this issue.

Workarounds

If you run Datasette behind a proxy you can workaround this issue by rejecting any incoming requests with ?_trace= or &_trace= in their query string parameters.
