Answer in brief
CVE-2026-71244 records a Medium severity (CVSS 6.5) vulnerability in Paperless-ngx: Mail Account Test Connection Leaks Stored IMAP/OAuth Credentials to Attacker-Controlled Host. The current sources do not mark it as known exploited. The current feed maps paperless-ngx/paperless-ngx (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Paperless-ngx's MailAccountViewSet.test() action, when called with an existing account's ID and a masked password field, reuses the stored password, account_type, refresh_token, and expiration from that existing account while allowing the caller to supply a different imap_server, imap_port, and imap_security in the same request. The test connection then authenticates to the caller-specified server using the real stored credentials. A user holding only object-level change_mailaccount permission on the target account (not full admin) can redirect the test connection to an attacker-controlled IMAP host, causing the real stored IMAP password or OAuth token to be sent to that host.
