{"id":"BIT-discourse-2022-23641","summary":"Denial of Service in Discourse","details":"Discourse is an open source discussion platform. In versions prior to 2.8.1 in the `stable` branch, 2.9.0.beta2 in the `beta` branch, and 2.9.0.beta2 in the `tests-passed` branch, users can trigger a Denial of Service attack by posting a streaming URL. Parsing Oneboxes in the background job trigger an infinite loop, which cause memory leaks. This issue is patched in version 2.8.1 of the `stable` branch, 2.9.0.beta2 of the `beta` branch, and 2.9.0.beta2 of the `tests-passed` branch. As a workaround, disable onebox in admin panel completely or specify allow list of domains that will be oneboxed.","aliases":["CVE-2022-23641","GHSA-22xw-f62v-cfxv"],"modified":"2025-10-08T05:27:00.309570Z","published":"2024-03-06T11:06:58.961Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/discourse/discourse/commit/a34075d205a8857e29574ffd82aaece0c467565e"},{"type":"WEB","url":"https://github.com/discourse/discourse/pull/15927"},{"type":"WEB","url":"https://github.com/discourse/discourse/security/advisories/GHSA-22xw-f62v-cfxv"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23641"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.8.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2022-23641.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
