CVE intelligence and bounded remediation

CVE-2026-44425 — ShellHub is a centralized SSH gateway

Medium CVSS 5.4

ShellHub is a centralized SSH gateway. Prior to 0.24.2, the device list endpoint accepts user-controlled identifiers in the the name field of each filter property in the base64-encoded filter query parameter and the sort_by query parameter, which are then passed directly as BSON/SQL keys in the database layer without validation. Any authenticated user can craft payloads that cause the aggregation / query to fail and the API to return HTTP 500 with no body, with no rate limiting applied. This vulnerability is fixed in 0.24.2.

Matched remediation archetype

SQL and data-query injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
  • Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
  • Check both direct queries and second-order use of previously stored values.

Remediate safely

  • Use parameterized queries or safe query builders for all values; map identifiers and operators through explicit allowlists.
  • Remove raw query concatenation and give the application account only the tables and operations it requires.
  • Update affected data-access components and add regression tests for query structure preservation with inert edge-case inputs.
