CVE intelligence and bounded remediation
CVE-2026-21892 — Parsl is a Python parallel scripting library
Parsl is a Python parallel scripting library. A SQL Injection vulnerability exists in the parsl-visualize component of versions prior to 2026.01.05. The application constructs SQL queries using unsafe string formatting (Python % operator) with user-supplied input (workflow_id) directly from URL routes. This allows an unauthenticated attacker with access to the visualization dashboard to inject arbitrary SQL commands, potentially leading to data exfiltration or denial of service against the monitoring database. Version 2026.01.05 fixes the issue.

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.
