{"id":"CVE-2026-50739","details":"A bypass for CVE‑2026‑34913 exists with proper ownership validation that had not been applied to the reverse operation of linking campaigns and trackers through the `tracker-campaigns.php` script in Revive Adserver 6.0.7 and earlier. As a result, a low‑privileged user could link their trackers to campaigns owned by other managers on the same instance, leading to inconsistent ownership relationships.","modified":"2026-07-15T01:49:12.329463025Z","published":"2026-06-26T01:11:14.071Z","database_specific":{"cwe_ids":["CWE-284"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50739.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"last_affected":"6.0.7"}]}],"cna_assigner":"hackerone"},"references":[{"type":"WEB","url":"https://hackerone.com/reports/3780709"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50739.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50739"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/revive-adserver/revive-adserver","events":[{"introduced":"0"},{"fixed":"cc962cd9f6cccc0bc4f5c74510cd6fdd08c18654"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:revive-adserver:revive_adserver:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"6.0.8"}]}}],"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-2026-50739.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:N/I:L/A:N"}]}
