CVE-2026-42093: Redash: SQL Injection via Query Results parameterized query substitution

HighCVSS 8.7 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.68% (FIRST EPSS); higher than 53% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: getredash redash 26.9.0.

Low priority for now. Upgrade to getredash redash 26.9.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Redash is a package for data visualization and sharing. From versions after 8.0.0 until 26.9.0, the Query Results query runner in redash/query_runner/query_results.py accepts param_query_N_{key=value} parameters and passed attacker-controlled values to replace_query_parameters() for raw substitution into a referenced query's SQL. This path bypassed the ParameterizedQuery schema validation used by normal query execution and omitted the is_safe permission check. An authenticated user with at least view-only access to both the Query Results data source and the referenced data source could therefore inject SQL through text parameters and execute it with the referenced data source's privileges. This issue is fixed in version 26.9.0.
