Attackers can exploit this flaw to force the server into SSRF requests, coerce NTLMv2 hash disclosure via attacker-controlled SMB shares, and read arbitrary files from the underlying Windows host through an out-of-band error-based channel. WebAdvisor entered end-of-support status in June 2022 and users are encouraged to migrate to Colleague Self-Service.","state":0,"publishedAt":"2026-10-15T01:31:06.896+00:00","modifiedAt":"2026-10-20T02:35:29.262+00:00","affected":[{"ecosystem":"Vendor product","name":"WebAdvisor","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"vendor\": \"Ellucian\",\n                    \"product\": \"WebAdvisor\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"3.2\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://www.ellucian.com/","https://www.vulncheck.com/advisories/ellucian-webadvisor-unauthenticated-xxe-injection"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109430","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109430","identifiers":["CVE-2026-109430"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
