{"id":"BIT-discourse-2024-24827","summary":"No rate limits on POST /uploads endpoint in Discourse","details":"Discourse is an open source platform for community discussion. Without a rate limit on the POST /uploads endpoint, it makes it easier for an attacker to carry out a DoS attack on the server since creating an upload can be a resource intensive process. Do note that the impact varies from site to site as various site settings like `max_image_size_kb`, `max_attachment_size_kb` and `max_image_megapixels` will determine the amount of resources used when creating an upload. The issue is patched in the latest stable, beta and tests-passed version of Discourse. Users are advised to upgrade. Users unable to upgrade should reduce `max_image_size_kb`, `max_attachment_size_kb` and `max_image_megapixels` as smaller uploads require less resources to process. Alternatively, `client_max_body_size` can be reduced in Nginx to prevent large uploads from reaching the server.","aliases":["CVE-2024-24827","GHSA-58vw-246g-fjj4"],"modified":"2026-09-08T08:46:25.643352435Z","published":"2024-04-01T14:04:36.691Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"]},"references":[{"type":"FIX","url":"https://github.com/discourse/discourse/commit/003b80e62f97cd8c0114d6b9d3f93c10443e6fae"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-58vw-246g-fjj4"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-24827"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2024-24827.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
