In the case of a security vulnerability report, we ask the reporter to send it directly to cert@nukib.gov.cz, if possible encrypted with the following PGP key: F60C 0622 EE75 52C9 7EE5 E9F8 4405 4AC1 A573 37A6. We usually fix reported and confirmed security vulnerabilities in less than 72 hours, followed by a software release containing the fixes within the following days.
