UBUNTU-CVE-2026-59856 (CVE-2026-59856)

Vulnerability from osv_ubuntu – Published: 2026-07-10 00:00 – Updated: 2026-07-14 21:41 – Source website

Details

Vim is an open source, command line text editor. Prior to 9.2.0736, the PHP omni-completion script in runtime/autoload/phpcomplete.vim interpolates a class or trait name, taken from the contents of the edited buffer, into a search() pattern that is run via win_execute() without escaping. A name containing a single quote can terminate the search() string argument early, and because the bar is honored as an Ex command separator, the remainder of the name is run as Ex commands; via the :! command this allows arbitrary operating-system command execution when a victim opens a crafted PHP file and invokes omni-completion. This issue is fixed in version 9.2.0736.

Prior to 9.2.0736, the PHP omni-completion script in runtime/autoload/phpcomplete.vim interpolates a class or trait name, taken from the contents of the edited buffer, into a search() pattern that is run via win_execute() without escaping. A name containing a single quote can terminate the search() string argument early, and because the bar is honored as an Ex command separator, the remainder of the name is run as Ex commands; via the :! command this allows arbitrary operating-system command execution when a victim opens a crafted PHP file and invokes omni-completion. This issue is fixed in version 9.2.0736."

Summary

vim vulnerabilities

Details

Hirohito Higashi discovered that Vim incorrectly escaped class or trait names when performing PHP omni-completion. An attacker could possibly use this issue to trick a user into opening a specially crafted PHP file and executing arbitrary commands. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-59856)

Hirohito Higashi discovered that Vim incorrectly handled sound-folding of certain words when using a spell file. An attacker could possibly use this issue to cause Vim to crash, resulting in a denial of service. (CVE-2026-59857)

It was discovered that Vim incorrectly escaped certain tags file fields when performing C omni-completion. An attacker could possibly use this issue to trick a user into opening a specially crafted file and executing arbitrary commands. (CVE-2026-59858)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
