Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.
CVE-2023-28206 is an out-of-bounds write vulnerability addressed through improved input validation in multiple Apple operating systems. The affected platforms include macOS Monterey prior to 12.6.5, macOS Ventura prior to 13.3.1, macOS Big Sur prior to 11.7.6, iOS and iPadOS prior to 16.4.1, and iOS and iPadOS prior to 15.7.5. The flaw carries a CVSS score of 8.6 and is classified under CWE-787.
An unprivileged local attacker can exploit the issue by supplying malicious input to a vulnerable application, potentially achieving arbitrary code execution with kernel-level privileges on the target device. The attack requires user interaction such as opening a crafted file or app.
Apple security advisories for the listed updates confirm that the vulnerability has been resolved in the specified releases and recommend that users install the patches promptly. The vendor notes awareness of reports indicating the issue may have been actively exploited in the wild prior to patching.
The associated EPSS score reached a peak of 0.2631 before receding to its current value of 0.2159, consistent with sustained but not sharply escalating post-disclosure interest in the flaw.
