{"id":"CVE-2022-39355","summary":"Discourse Patreon vulnerable to improper validation of email during Patreon authentication","details":"Discourse Patreon enables syncronization between Discourse Groups and Patreon rewards. On sites with Patreon login enabled, an improper authentication vulnerability could be used to take control of a victim's forum account. This vulnerability is patched in commit number 846d012151514b35ce42a1636c7d70f6dcee879e of the discourse-patreon plugin. Out of an abundance of caution, any Discourse accounts which have logged in with an unverified-email Patreon account will be logged out and asked to verify their email address on their next login. As a workaround, disable the patreon integration and log out all users with associated Patreon accounts.","aliases":["GHSA-fvj9-f67v-qpr4"],"modified":"2026-08-12T03:51:13.874619021Z","published":"2022-10-26T00:00:00Z","database_specific":{"cwe_ids":["CWE-287"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39355.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"846d012151514b35ce42a1636c7d70f6dcee879e"}]}],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39355.json"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse-patreon/security/advisories/GHSA-fvj9-f67v-qpr4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39355"},{"type":"FIX","url":"https://github.com/discourse/discourse-patreon/commit/846d012151514b35ce42a1636c7d70f6dcee879e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/discourse/discourse-patreon","events":[{"introduced":"0"},{"fixed":"846d012151514b35ce42a1636c7d70f6dcee879e"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-39355.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
