{"id":"CVE-2026-40588","summary":"blueprintUE: Authenticated Password Change Does Not Verify Current Password","details":"blueprintUE is a tool to help Unreal Engine developers. Prior to 4.2.0, the password change form at /profile/{slug}/edit/ does not include a current_password field and does not verify the user's existing password before accepting a new one. Any attacker who obtains a valid authenticated session — through XSS exploitation, session sidejacking over HTTP, physical access to a logged-in browser, or a stolen \"remember me\" cookie — can immediately change the account password without knowing the original credential, resulting in permanent account takeover. This vulnerability is fixed in 4.2.0.","aliases":["GHSA-73f2-p9jr-m44x"],"modified":"2026-07-15T01:49:00.861082681Z","published":"2026-04-21T17:12:08.938Z","database_specific":{"cwe_ids":["CWE-620"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40588.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40588.json"},{"type":"ADVISORY","url":"https://github.com/blueprintue/blueprintue-self-hosted-edition/security/advisories/GHSA-73f2-p9jr-m44x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40588"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/blueprintue/blueprintue-self-hosted-edition","events":[{"introduced":"0"},{"fixed":"28689950b0fc1c6a0c5db2a034a03fdc9747467c"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.2.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v4.1.2","v4.1.1","v4.1.0","v4.0.0","v3.2.0","v3.1.0","v3.0.0","v2.1.0","v2.0.1","v2.0.0","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40588.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
