It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-59858 in the wild and no public exploit code.\n\nAffected product: Vim Vim. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-59858/ (Markdown: https://insights.sbomify.com/CVE-2026-59858/index.md)","id":"CVE-2026-59858","markdown":"https://insights.sbomify.com/CVE-2026-59858/index.md","name":"CVE-2026-59858","record":{"aliases":["ALPINE-CVE-2026-59858","BELL-CVE-2026-59858","CLSA-2026-1784036814","CLSA-2026-1784038367","CLSA-2026-1784042868","CLSA-2026-1784799349","CLSA-2026-1784799471","CLSA-2026-1784799711","CLSA-2026-1784802165","CLSA-2026-1784807557","CLSA-2026-1786353169","DEBIAN-CVE-2026-59858","ECHO-60cb-ca68-ea06","GHSA-mf92-v4xw-j45x","MINI-jj46-p349-6r9v","ROOT-OS-DEBIAN-11-CVE-2026-59858","ROOT-OS-DEBIAN-12-CVE-2026-59858","UBUNTU-CVE-2026-59858"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Vim text editor","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening a malicious C file with a crafted tags file, triggering unsafe command execution in Vim.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vim","vendor":"vim"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"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","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Vim is an open source, command line text editor. Prior to 9.2.0735, the C omni-completion script in runtime/autoload/ccomplete.vim interpolates the typeref: or typename: extension field of a tags entry, without escaping, into a :vimgrep pattern that is run through :execute. Because :vimgrep honors the bar as a command separator, a crafted tag field can close the search pattern and append an arbitrary Ex command; opening a hostile .c file whose project tags file contains such an entry and invoking C omni-completion runs that command as the editing user.
