Datalust Seq before 2023.2.9489 allows insertion of sensitive information into an externally accessible file or directory. This is exploitable only when external (SQL Server or PostgreSQL) metadata storage is used. Exploitation can only occur from a high-privileged user account.

Datalust Seq.App.EmailPlus (aka seq-app-htmlemail) 3.1.0-dev-00148, 3.1.0-dev-00170, and 3.1.0-dev-00176 can use cleartext SMTP on port 25 in some cases where encryption on port 465 was intended.

Datalust Seq before 2021.2.6259 allows users (with view filters applied to their accounts) to see query results not constrained by their view filter. This information exposure, caused by an internal cache key collision, occurs when the user's view filter includes an array or IN clause, and when another user has recently executed an identical query differing only by the array elements.

Datalust Seq before 4.2.605 is vulnerable to Authentication Bypass (with the attacker obtaining admin access) via '"Name":"isauthenticationenabled","Value":false' in an api/settings/setting-isauthenticationenabled PUT request.
