## What is CVE-2026-42093?

CVE-2026-42093 is a high-severity SQL injection vulnerability in getredash redash, published on 14 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)

What it is: CVE-2026-42093 is a high-severity SQL injection vulnerability in getredash redash, published on 14 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-42093 exists.

Affected product: getredash redash. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
