{"id":"CVE-2026-50744","details":"A bypass to the admin‑only restriction of the XML‑RPC API in Revive Adserver 6.0.7. The API response for the ox.login method returned a session ID cookie in the HTTP headers, and although the method correctly returned an error, the associated session was not invalidated. As a result, the leaked session ID could be used to perform subsequent API calls without restrictions.","modified":"2026-07-15T01:48:54.061691330Z","published":"2026-06-26T01:11:14.060Z","database_specific":{"cna_assigner":"hackerone","cwe_ids":["CWE-284"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50744.json","unresolved_ranges":[{"extracted_events":[{"last_affected":"6.0.7"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"WEB","url":"https://hackerone.com/reports/3783738"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50744.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50744"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/revive-adserver/revive-adserver","events":[{"introduced":"0"},{"fixed":"cc962cd9f6cccc0bc4f5c74510cd6fdd08c18654"}],"database_specific":{"cpe":"cpe:2.3:a:revive-adserver:revive_adserver:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"6.0.8"}],"source":"CPE_RANGE"}}],"versions":["v6.0.7","v6.0.6","v6.0.5","v6.0.4","v6.0.3","v6.0.2","v6.0.1","v6.0.0","v5.4.1","v5.4.0","v5.4.0-rc1","v5.3.0","v5.3.0-rc1","v5.2.1","v5.2.0","v5.1.1","v5.1.0","v5.1.0-rc1","v5.0.5","v5.0.4","v5.0.3","v5.0.1","v5.0.0","v5.0.0-rc1","v4.2.1","v4.2.0","v4.2.0-rc1","v4.1.4","v4.1.3","v4.1.2","v4.1.0","v4.1.0-rc1","v4.0.2","v4.0.1","v4.0.0","v4.0.0-rc1","v3.2.1","v3.2.1-rc1","v3.2.0","v3.2.0-beta","v3.1.0","v3.1.0-beta","v3.0.3","v3.0.2","v3.0.1","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50744.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
