{"id":"CVE-2026-79313","published":"2026-09-22T15:17:15.467","lastModified":"2026-09-22T20:17:08.790","description":"webpy web.py 0.76 is vulnerable to Insufficient Session Expiration. The application's session management relies on periodic cleanup to expire sessions instead of checking the last-access time when a session is loaded. As a result, an expired session whose record has not yet been cleaned up can still be replayed and used, allowing an attacker holding a previously valid session cookie to continue accessing protected resources after the configured idle timeout.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-613"],"vendors":[],"products":[],"references":[{"url":"https://github.com/lichoin/TraceLoom/blob/main/CVEs/CVE-2026-79313.md","tags":[]},{"url":"https://github.com/webpy/webpy","tags":[]}],"exploitRefs":[{"url":"https://github.com/lichoin/TraceLoom/blob/main/CVEs/CVE-2026-79313.md","tags":[]},{"url":"https://github.com/webpy/webpy","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker to replay an expired session, gaining unauthorized access to protected resources. This is critical as it bypasses the intended session expiration mechanism.","exploitability":"Exploitation is relatively straightforward if an attacker has access to a valid session cookie. The attacker must wait for the session to expire and then replay it.","blast_radius":"If exploited, the attacker can access protected resources, potentially leading to data theft or system compromise.","remediation":"Upgrade to web.py 0.77 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","session-expiration"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-27T08:49:33.406Z"}}
