CVE-2021-41163

9.8 criticalEPSS 20%

Critical (9.8) in discourse discourse. EPSS 20% chance of exploitation in the next 30 days.

Discourse is an open source platform for community discussion. In affected versions maliciously crafted requests could lead to remote code execution. This resulted from a lack of validation in subscribe_url values. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. To workaround the issue without updating, requests with a path starting /webhooks/aws path could be blocked at an upstream proxy.
