CVE-2024-8270
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe macOS Rocket.Chat application lacks Hardened Runtime signing and does not enforce Library Validation, allowing DYLIB injection attacks that bypass TCC (Transparency, Consent, and Control) policies. This enables attackers to abuse entitlements (microphone, camera, automation, network client) and escalate privileges beyond what the application's sandbox profile permits.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the Rocket.Chat applicationOpen Terminal and run: find /Applications -name 'Rocket.Chat*' -type d 2>/dev/null | head -5Affected if Rocket.Chat application is not found in /Applications
-
Verify Hardened Runtime is enabledRun: codesign -dv --entitlements - '/path/to/Rocket.Chat.app' 2>&1 | grep -i 'runtime'Affected if The output does not contain 'runtime' or shows Hardened Runtime is disabled
-
Check if Library Validation is enforcedRun: codesign -dv --entitlements - '/path/to/Rocket.Chat.app' 2>&1 | grep -i 'library'Affected if Library Validation is not present or disabled in the code signature
-
Inspect application entitlementsRun: codesign -dv --entitlements - '/path/to/Rocket.Chat.app' 2>&1Affected if The entitlements include microphone, camera, automation, or network client permissions without Hardened Runtime protection
If Rocket.Chat is installed and either Hardened Runtime is disabled or Library Validation is not enforced, the environment is vulnerable to DYLIB injection and TCC bypass attacks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSign the Rocket.Chat application with Hardened Runtime enabled and enforce Library Validation to prevent DYLIB injection attacks and TCC policy bypass.
