CVE-2026-33412: Vim affected by Command injection via newline in glob()

Vim is an open source, command line text editor. Prior to version 9.2.0202, a command injection vulnerability exists in Vim's glob() function on Unix-like systems. By including a newline character (\n) in a pattern passed to glob(), an attacker may be able to execute arbitrary shell commands. This vulnerability depends on the user's 'shell' setting. This issue has been patched in version 9.2.0202.

Security readout for executives and security teams

Plain-English summary

Vim before 9.2.0202 can be tricked into running shell commands when its glob() function receives a pattern containing a newline on Unix-like systems. The bug needs local/user interaction conditions, but successful exploitation could compromise confidentiality, integrity, and availability under the affected user context.

Executive priority

Treat as a high-priority patching item for Unix-like systems with Vim installed, especially developer systems and shared servers. It is not described as remotely exploitable in the provided sources, but impact is high if triggered.

Technical view

CVE-2026-33412 is CWE-78 command injection in Vim glob() on Unix-like systems. A newline in a glob pattern can alter shell command handling, depending on the user's 'shell' setting. Upstream fixed the issue in Vim 9.2.0202. CVSS 3.1 is 7.3: AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H.

Likely exposure

Unix-like workstations, servers, containers, and developer environments running Vim versions earlier than 9.2.0202 are in scope. Exposure is most relevant where Vim processes attacker-influenced patterns through glob(), including local scripts, plugins, or editor workflows that handle untrusted input.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires local privileges and user interaction per the CVSS vector, and it depends on Vim configuration, especially the user's 'shell' setting.

Researcher notes

Key constraints are newline handling in glob(), Unix-like behavior, the configured shell, and whether attacker-controlled data can reach glob(). Do not assume all Vim use is exploitable; validate call paths and package backport status.

Mitigation direction

  • Upgrade Vim to version 9.2.0202 or later.
  • Apply vendor-packaged fixes, including relevant Red Hat security advisories where applicable.
  • Check OS vendor guidance for backported fixed package versions.
  • Restrict untrusted Vim scripts, plugins, or workflows until patched.

Validation and detection

  • Inventory Vim versions across Unix-like endpoints, servers, containers, and images.
  • Confirm installed packages include the upstream fix or vendor backport.
  • Review vendor advisory status for each affected distribution.
  • Identify Vim workflows that pass untrusted input into glob().
