Affected fields: email_password, email_username, smtp_server, smtp_port, smtp_ssl_mode. The most sensitive item is the SMTP password, which an owner could use to send mail as the group from outside Discourse. This impacts sites that have configured per-group SMTP credentials and granted group ownership to users who should not have access to those credentials. This issue has been patched in versions 2026.1.4, 2026.3.1, 2026.4.1, and 2026.5.0-latest.1."}], "lastModified": "2026-06-17T18:50:24.733", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C4B2317D-D085-4564-8D41-AD4EBA6F61BF", "versionEndExcluding": "2026.1.0"}, {"criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E82B178E-8F1C-4AD6-A18A-649091C3BCFE", "versionEndExcluding": "2026.1.4", "versionStartIncluding": "2026.1.0"}, {"criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "53A8996E-FEBF-43B0-92E6-38ECC9381013", "versionEndExcluding": "2026.3.1", "versionStartIncluding": "2026.3.0"}, {"criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CD3531A1-E4CB-42E5-BEE0-80C443DBEDEE", "versionEndExcluding": "2026.4.1", "versionStartIncluding": "2026.4.0"}, {"criteria": "cpe:2.3:a:discourse:discourse:2026.5.0:*:*:*:latest:*:*:*", "vulnerable": true, "matchCriteriaId": "8AD4BB38-1D03-4ECD-BFAB-900D57689A31"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
