This weakness allows an attacker to obtain valid access tokens for user accounts even after they have been blocked by the user store, bypassing account lockout mechanisms.\n\nThis vulnerability can lead to unauthorized access to user accounts and their associated resources. Attackers can leverage this to perform actions on behalf of blocked users, potentially leading to privilege escalation or data exfiltration depending on the permissions of the compromised account.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N","score":4.9},"cwes":["CWE-613"],"references":["https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2024-3676/"],"reference_tags":[{"url":"https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2024-3676/","tags":[]}],"products":[],"affected":[],"source":"nvd","synced_at":"2026-11-02T12:34:50.956170480+00:00"},"epss":null,"kev":null,"exploits":[],"weaknesses":[{"name":"DEPRECATED: Insufficient Session Expiration","common_name":null,"deprecated":true,"replaced_by":["CWE-1463","CWE-1464"],"id":"CWE-613"}],"osv":[],"fixed":[],"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).
