The secret therefore has at most 2**32 possible values, and one signed cookie is enough to test each candidate offline.\n\nAn attacker who obtains a single session cookie can recover the secret and sign cookies for any user, including an administrator.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-338"],"references":["https://metacpan.org/release/OETIKER/CallBackery-0.62.0/changes"],"products":[],"source":"nvd","synced_at":"2026-10-30T14:33:49.494135507+00:00"},"epss":null,"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).
