CVE-2021-30713 is a macOS vulnerability in Apple’s Transparency, Consent, and Control (TCC) privacy framework that was fixed in macOS Big Sur 11.4. Apple described the issue as a permissions problem addressed through improved validation. Successful exploitation allows a malicious application to bypass Privacy preferences and inherit or obtain TCC-governed permissions without the user’s explicit approval. Reporting on in-the-wild abuse linked the flaw to XCSSET malware, which used the bypass to access screen-recording-related capabilities and capture screenshots without triggering the expected consent prompt. Analysis of the abuse indicated the issue could be leveraged by placing a malicious app component within the bundle of an already trusted or previously authorized application so that the malicious component inherited the parent application's TCC permissions.
