CVE-2021-41329
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDatalust 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Seq 2021.2.6259 or later
- 1. Identify the current Seq version by checking the Seq UI footer or running `seq show` in the CLI
- 2. If running a version before 2021.2.6259, plan the upgrade during a maintenance window
- 3. Backup the Seq data directory before upgrading (default location: /data on Linux, C:\Seq on Windows)
- 4. Upgrade to Seq version 2021.2.6259 or later using your deployment method (Docker, installer, or package manager)
- 5. After upgrade, verify the Seq service is running and accessible
- 6. Log in as an administrator and confirm the version shows 2021.2.6259 or later
- 7. Test that view filters with array/IN clauses properly constrain query results for restricted users
