Log disclosure via server-controlled format strings
Published Apr 30, 2026 · Updated Apr 30, 2026
Absolute Secure Access before 14.50 has format string injection that allows attackers to expose macOS client memory through a modified server. The logging subsystem treats server-controlled text as a format string, causing formatting directives to read memory values and write them into client log files. Exploitation requires control of the server used by the client; the vendor limits the disclosure to a small memory region and reports no data modification or service interruption.
