Last modified Jun 17, 2026

CVE-2024-8926 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, when using a certain non-standard configurations of Windows codepages, the fixes for CVE-2024-4577 https://github.com/advisories/GHSA-vxpp-6299-mxw3 may still be bypassed and the same command injection related to Windows "Best Fit" codepage behavior can be achieved. This may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc.. EPSS estimates a 3.69% chance of exploitation in the next 30 days.
