Reflected cross-site scripting issue in Datasette
🔗 CVE IDs covered (1)
📋 Description
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.
