ImpressCMS before 1.4.3 has Incorrect Access Control because include/findusers.php allows access by unauthenticated attackers (who are, by design, able to have a security token).
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 10.5%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
