CVE-2021-37633 Information

Description

Discourse is an open source discussion platform. In versions prior to 2.7.8 rendering of d-popover tooltips can be susceptible to XSS attacks. This vulnerability only affects sites which have modified or disabled Discourse’s default Content Security Policy. This issue is patched in the latest stable 2.7.8 version of Discourse. As a workaround users may ensure that the Content Security Policy is enabled and has not been modified in a way which would make it more vulnerable to XSS attacks.
