CVE-2025-1348

Local browser-cache disclosure via unsuitable caching policy

Published Jun 18, 2025 · Updated Aug 24, 2025

Improper cache management in IBM Sterling B2B Integrator allows local users to read sensitive data from a user's web browser cache. Affected web responses apply an unsuitable caching policy, so the browser retains sensitive content that should not remain cached. Local access to that browser cache is required, and disclosure is limited to content previously rendered for that browser user.
