Code Injection in Vim - CVE-2026-59856

Vulnerability identifier: #VU135702

CSH Severity: High

CVSS v4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-59856

CWE-ID: CWE-94

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper control of code generation in runtime/autoload/phpcomplete.vim when processing a crafted PHP file during omni-completion. A remote attacker can trick the victim into opening a crafted file and invoking omni-completion to execute arbitrary code.

User interaction is required to open a crafted PHP file and manually invoke omni-completion, and exploitation requires filetype plugins to be enabled.
