CVE intelligence and bounded remediation
CVE-2024-29890 — DataLens is a business intelligence and data visualization system
DataLens is a business intelligence and data visualization system. A specifically crafted request allowed the creation of a special chart type with the ability to pass custom javascript code that would later be executed in an unprotected sandbox on subsequent requests to that chart. The problem was fixed in the datalens-ui version `0.1449.0`. Restricting access to the API for creating or modifying charts (`/charts/api/charts/v1/`) would mitigate the issue.

Matched remediation archetype
Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
