CVE-2023-49313

Status: ModifiedCritical (9.8)—💥 PoC

A dylib injection vulnerability in XMachOViewer 0.04 allows attackers to compromise integrity. By exploiting this, unauthorized code can be injected into the product's processes, potentially leading to remote control and unauthorized access to sensitive user data.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
