What is CVE-2024-8270?
CVE-2024-8270 is a medium-severity vulnerability in Rocket.Chat Desktop, published on 10 Jun 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The macOS Rocket.Chat application is affected by a vulnerability that allows bypassing Transparency, Consent, and Control (TCC) policies, enabling the exploitation or abuse of permissions specified in its entitlements (e.g., microphone, camera, automation, network client). Since Rocket.Chat was not signed with the Hardened Runtime nor set to enforce Library Validation, it is vulnerable to DYLIB injection attacks, which can lead to unauthorized actions or escalation of permissions. Consequently, an attacker gains capabilities that are not permitted by default under the Sandbox and its application profile.
Weakness: CWE-863
