## Technical details

The vulnerability is an improper limitation of pathname access (CWE-22) in Adobe Connect's file handling logic. It requires authentication (PR:L) but can be exploited over the network without user interaction (AV:N, UI:N). Successful exploitation allows an authenticated attacker to traverse directory structures and read files outside the intended access scope, potentially leading to arbitrary code execution when combined with other system capabilities (S:C scope change).
