The weakness is a logical comparison error that bypasses expected safeguards and can result in prolonged unauthorized access.", "risk_and_exploitability": "The CVSS base score of 5.3 reflects a medium severity. No EPSS score is currently reported and the vulnerability is not listed in the CISA KEV catalog, indicating a lower likelihood of widespread exploitation. However, the attack requires an authenticated user with permission to update session data, which is common in many applications. Because the vulnerability allows an attacker to keep a session alive indefinitely, it can facilitate sustained, undetected abuse and data exfiltration for as long as the session remains active."}}}}, "created": "2026-03-31T19:54:14.458601+00:00", "updated": "2026-03-31T20:38:10.608408+00:00", "vendors": ["parse_community", "parse_community$PRODUCT$parse_server"]}
