CVE-2021-32670
Good to know:
Date: June 7, 2021
Datasette is an open source multi-tool for exploring and publishing data. The "?_trace=1" debugging feature in Datasette does not correctly escape generated HTML, resulting in a "reflected cross-site scripting" (https://owasp.org/www-community/attacks/xss/#reflected-xss-attacks) vulnerability. This vulnerability is particularly relevant if your Datasette installation includes authenticated features using plugins such as "datasette-auth-passwords" (https://datasette.io/plugins/datasette-auth-passwords) as an attacker could use the vulnerability to access protected data. Datasette 0.57 and 0.56.1 both include patches for this issue. 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.
