Deeper analysis
CVE-2023-49313 is a dylib injection vulnerability affecting XMachOViewer version 0.04. The flaw, classified under CWE-94, permits unauthorized code to be injected into the application's processes and thereby compromises integrity. The issue carries a CVSS 3.1 score of 9.8 with a network attack vector requiring no authentication or user interaction.
An attacker able to supply a malicious dylib can achieve remote code execution inside the viewer process, resulting in full control of the application and potential unauthorized access to sensitive user data on the host system.
The EPSS score for the vulnerability rose from a low baseline to a recorded peak of 0.0537 on 2025-12-18 before receding to the current value of 0.0417, indicating a measurable increase in exploitation interest after public disclosure. The primary references consist of the project's GitHub repository and a dedicated proof-of-concept repository, with no additional mitigation guidance provided in the available sources.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
