Code Injection in Vim - CVE-2026-59858

Vulnerability identifier: #VU135701

CSH Severity: Medium

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-2026-59858

CWE-ID: CWE-94

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to improper neutralization of special elements in the C omni-completion script in runtime/autoload/ccomplete.vim when processing type information from a tags entry during omni-completion. A local user can supply a crafted tags entry and trick the victim into invoking C omni-completion on a hostile .c file to execute arbitrary code.

User interaction is required to open a hostile .c file and invoke omni-completion on a structure-member access, and the issue is reachable only when filetype plugins are enabled and a reachable tags file is used.
