{"id":"AZL-98304","summary":"CVE-2026-33606 affecting package dovecot 2.3.20-1","details":"Mail content stored by a user can be crafted so that it is interpreted as dsync protocol commands when an administrator later runs dsync with the stream protocol, for example during a migration. Injected commands can modify mailbox state on the destination during migration or replication, including internal mailbox attributes that a user should not be able to set directly. It can also cause dsync errors. Avoid running dsync with the stream protocol on mailboxes with untrusted content. Update to non-vulnerable version. No publicly available exploits are known.","modified":"2026-09-03T05:28:38Z","published":"2026-08-28T12:16:27Z","upstream":["CVE-2026-33606"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33606"}],"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-98304.json"}}],"schema_version":"1.9.0"}
