{"id":"AZL-98325","summary":"CVE-2026-42008 affecting package dovecot 2.3.20-1","details":"Forwarding information received from a host listed as a trusted proxy is not kept separate from Dovecot's own authentication fields, so a value sent by that host can be injected as an internal authentication field. Any host permitted to act as a trusted proxy can authenticate as any user without knowing that user's password. This affects deployments whose password database honours a field that permits authentication without a password. Deployments that do not configure trusted proxies are not affected. Restrict the list of trusted proxy networks to hosts that are fully under your control. Update to non-vulnerable version. No publicly available exploits are known.","modified":"2026-09-05T05:24:22Z","published":"2026-08-28T12:16:29Z","upstream":["CVE-2026-42008"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42008"}],"affected":[{"package":{"name":"dovecot","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.3.20-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-98325.json"}}],"schema_version":"1.9.0"}
