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.","state":0,"publishedAt":"2026-08-21T18:05:20.458+00:00","modifiedAt":"2026-08-21T19:22:22.158+00:00","affected":[{"ecosystem":"Vendor product","name":"unleash","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Unleash\",\n                    \"product\": \"unleash\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.5.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 7.6.0, < 7.6.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 8.0.0, < 8.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","score":5.5,"severity":"MEDIUM"}],"references":["https://github.com/Unleash/unleash/security/advisories/GHSA-5vf6-jrqr-78fj","https://github.com/Unleash/unleash/commit/2100db76af3473f13e6fb40096cf17a9c2b741a1","https://github.com/Unleash/unleash/commit/d45f99df924c0d24747b3e45e46fcda7dcd3c1c1","https://github.com/Unleash/unleash/commit/d862562a5ab8f2d1e40f6519c64cf0b4fdaf806d","https://github.com/Unleash/unleash/releases/tag/v7.5.2","https://github.com/Unleash/unleash/releases/tag/v7.6.5","https://github.com/Unleash/unleash/releases/tag/v8.0.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-63004","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-63004","identifiers":["CVE-2026-63004"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
