By sending a specially crafted host header in the reset password request, it is possible to send password reset links to users which, once clicked, lead to an attacker-controlled server and thus leak the password reset token. This allows an attacker to reset other users' passwords.","published":"2023-09-28T00:00:00Z","modified":"2026-08-12T03:51:31.623609704Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Packagist","name":"gugoan/economizzer","fixedVersion":null}],"fix":{"url":"https://github.com/gugoan/economizzer/commit/37308802dfe00d43df396a8afaa2096ece8b7b57","label":"gugoan/economizzer@3730880"},"references":[{"type":"WEB","url":"https://github.com/dub-flow/vulnerability-research/tree/main/CVE-2023-38877"},{"type":"WEB","url":"https://github.com/gugoan/economizzer/"},{"type":"WEB","url":"https://www.economizzer.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/38xxx/CVE-2023-38877.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-38877"},{"type":"WEB","url":"https://github.com/gugoan/economizzer/commit/37308802dfe00d43df396a8afaa2096ece8b7b57"},{"type":"WEB","url":"https://github.com/gugoan/economizzer"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:31.623609704Z"}}
