{"cve":"CVE-2023-31287","nvd":{"published":"2023-04-27T03:15:10.200","modified":"2026-06-17T05:56:43.577","status":"Modified","description":"An issue was discovered in Serenity Serene (and StartSharp) before 6.7.0. Password reset links are sent by email. A link contains a token that is used to reset the password. This token remains valid even after the password reset and can be used a second time to change the password of the corresponding user. The token expires only 3 hours after issuance and is sent as a query parameter when resetting. An attacker with access to the browser history can thus use the token again to change the password in order to take over the account.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-640"],"references":["http://packetstormsecurity.com/files/172648/Serenity-StartSharp-Software-File-Upload-XSS-User-Enumeration-Reusable-Tokens.html","http://seclists.org/fulldisclosure/2023/May/14","https://github.com/serenity-is/Serenity/commit/11b9d267f840513d04b4f4d4876de7823a6e48d2","http://packetstormsecurity.com/files/172648/Serenity-StartSharp-Software-File-Upload-XSS-User-Enumeration-Reusable-Tokens.html","http://seclists.org/fulldisclosure/2023/May/14"],"products":["serenity:serene","serenity:startsharp"],"source":"nvd","synced_at":"2026-10-19T21:38:05.473481323+00:00"},"epss":{"cve":"CVE-2023-31287","score":0.00435,"percentile":0.37828,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
