Summary

CVE-2023-44367 is a high-severity Use After Free (CWE-416) vulnerability in Apple Macos. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked in the top 18% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Adobe Acrobat Reader versions 23.006.20360 and earlier, along with versions 20.005.30524 and earlier, contain a Use After Free vulnerability tracked as CVE-2023-44367 and CWE-416. The flaw can permit arbitrary code execution in the context of the current user when triggered.

An attacker can exploit the issue by supplying a malicious file that the victim must open, after which code runs locally with the privileges of the user who opened the document. No additional authentication or elevated privileges are required beyond the file-opening action.

Adobe’s advisory APSB23-54, referenced at helpx.adobe.com, addresses the vulnerability and directs users to apply the vendor-supplied updates that remediate the use-after-free condition in the affected Acrobat Reader releases.

The associated EPSS score rose sharply from a low baseline to a peak of 0.5359 on 2025-01-22 before receding to its current value of 0.0141, indicating that exploitation interest increased substantially after disclosure.
