CVE-2023-23303
The `Toybox.Ant.GenericChannel.enableEncryption` API method in CIQ API version 3.2.0 through 4.1.7 does not validate its parameter, which can result in buffer overflows when copying various attributes.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.79%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
