This results in users receiving tokens before the intended release date, undermining the intended allocation and potentially resulting in financial loss for token holders or depositors.

EPSS is reported as less than 1\u202f%, suggesting a low probability of exploitation at present. The vulnerability is not listed in the CISA KEV catalog.

No public exploit has been disclosed, but the flaw allows an attacker with transactional access to claim vested tokens early, thereby gaining an advantage in token distribution."}}}}, "created": "2026-03-06T15:01:05.950471+00:00", "updated": "2026-04-16T12:15:35.092147+00:00", "vendors": ["graphprotocol", "graphprotocol$PRODUCT$contracts"]}
