SCA: security update for unleash-server (GHSA-5vf6-jrqr-78fj)

medium Tenable Self-Hosted Container Security Plugin ID 446238

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-63004)

Solution

Update the unleash-server library and its related packages to version 7.5.2 or later.
