From 10.5.2 until 10.6.15, the isBlockedIP SSRF guard in internal/notification/dispatcher/webhook.go, used by safeDialContext for webhook notification URLs, does not inspect IPv4 addresses embedded in 6to4, NAT64, Teredo, or IPv4-compatible IPv6 addresses, allowing an authenticated user to reach loopback or link-local targets that the guard intends to block. This issue is fixed in version 10.6.15.","published":"2026-08-11T16:52:13.728Z","modified":"2026-08-14T04:02:10.066037862Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/amir20/dozzle","fixedVersion":"1.29.1-0.20260804193351-8cf7ccd5ee04"}],"fix":{"url":"https://github.com/amir20/dozzle/commit/8cf7ccd5ee041ecaea92b49951793d4d2393761f","label":"amir20/dozzle@8cf7ccd"},"references":[{"type":"WEB","url":"https://github.com/amir20/dozzle/releases/tag/v10.6.15"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73087.json"},{"type":"ADVISORY","url":"https://github.com/amir20/dozzle/security/advisories/GHSA-p2w3-6x73-2f6x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73087"},{"type":"FIX","url":"https://github.com/amir20/dozzle/commit/8cf7ccd5ee041ecaea92b49951793d4d2393761f"},{"type":"FIX","url":"https://github.com/amir20/dozzle/pull/4887"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:02:10.066037862Z"}}
