CVE-2026-79313 (GCVE-0-2026-79313)

Vulnerability from cvelistv5 – Published: 2026-09-22 00:00 – Updated: 2026-09-22 19:17
VLAI
Summary
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.
Severity
