The `secretKey` value is an important key for HMAC SHA256 authentication and in affected versions was stored in the database in cleartext form. If a malicious person somehow had access to the data in the database, they could use the key and secretKey for HMAC SHA256 authentication to send requests impersonating that corresponding user. This issue has been addressed in version 1.0.0-beta.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-312"],"references":["https://github.com/codeigniter4/shield/commit/f77c6ae20275ac1245330a2b9a523bf7e6f6202f","https://github.com/codeigniter4/shield/security/advisories/GHSA-v427-c49j-8w6x","https://github.com/codeigniter4/shield/commit/f77c6ae20275ac1245330a2b9a523bf7e6f6202f","https://github.com/codeigniter4/shield/security/advisories/GHSA-v427-c49j-8w6x"],"products":["codeigniter:shield"],"source":"nvd","synced_at":"2026-10-19T21:42:07.670898610+00:00"},"epss":{"cve":"CVE-2023-48707","score":0.00284,"percentile":0.20928,"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).
