As of 2026-10-05, deps.dev lists no known advisories for this version. That is a snapshot and not a promise: new advisories can be published at any time.
If you ship a product that includes tzdata, the Cyber Resilience Act expects you to know which components you ship, to follow their vulnerabilities and to exercise due diligence on third-party components (Annex I, Part II and Article 13). In practice: list tzdata 2026.5.0 in your SBOM with its package URL pkg:pypi/[email protected], watch for new advisories, and keep the upstream security contact in your vulnerability handling process.
