{"id":"BIT-discourse-2021-41163","summary":"RCE via malicious SNS subscription payload","details":"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.","aliases":["CVE-2021-41163","GHSA-jcjx-pvpc-qgwq"],"modified":"2026-09-08T08:46:04.156973631Z","published":"2024-03-06T11:09:16.561Z","database_specific":{"cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"],"severity":"Critical"},"references":[{"type":"ADVISORY","url":"https://github.com/discourse/discourse/commit/fa3c46cf079d28b086fe1025349bb00223a5d5e9"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-jcjx-pvpc-qgwq"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-41163"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.7.9"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2021-41163.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
