AI Analysis
Technical Summary
This vulnerability allows a malicious builder peer to request an in-context file by name from the host system and receive the contents of that file, regardless of whether the file resides outside the build context. This could lead to unauthorized disclosure of host files. The issue affects Apple container versions prior to 1.2.0 and is resolved in version 1.2.0.
Potential Impact
An attacker with builder peer capabilities can access arbitrary files on the host system outside the build context, potentially exposing sensitive information. There is no indication of active exploitation in the wild. The impact is unauthorized information disclosure limited to file contents accessible by name.
Mitigation Recommendations
Upgrade Apple container to version 1.2.0 or later, where this vulnerability is addressed. No other mitigation guidance is provided or required.
