Unleash is an open-source feature management platform. Prior to 7.5.2, 7.6.5, and 8.0.2, the addon and integration subsystem passes the operator-controlled parameters.url value from src/lib/addons/webhook.ts and the Slack, Microsoft Teams, Datadog, and New Relic integrations to Addon.fetchRetry in src/lib/addons/addon.ts without restricting loopback, link-local, private, or cloud metadata addresses. An authenticated actor with the root CREATE_ADDON or UPDATE_ADDON permission can cause the server to send requests from inside its network boundary, use integration event status as a blind probing oracle, forward Authorization, customHeaders, or DD-API-KEY values to an attacker-observed host, and deliver the feature-event JSON body to internal services. This issue is fixed in versions 7.5.2, 7.6.5, and 8.0.2.
