CVE-2021-23824 Information

Description

This affects the package Crow before 0.3+4. When using attributes without quotes in the template an attacker can manipulate the input to introduce additional attributes potentially executing code. This may lead to a Cross-site Scripting (XSS) vulnerability assuming an attacker can influence the value entered into the template. If the template is used to render user-generated content this vulnerability may escalate to a persistent XSS vulnerability.
