What is CVE-2026-52860?

Vim, a widely-used open source command line text editor, has a vulnerability in its Python omni-completion feature that allows for code execution. Specifically, prior to version 9.2.0597, Vim executed reconstructed function and class definitions using Python's exec() function while populating the completion dictionary. This poses a risk as an attacker could craft a malicious buffer that executes arbitrary Python code during omni-completion, bypassing existing mitigation measures. A security patch has been released in version 9.2.0597 to address this vulnerability.
