An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-26269 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-2026-26269/ (Markdown: https://insights.sbomify.com/CVE-2026-26269/index.md)","id":"CVE-2026-26269","markdown":"https://insights.sbomify.com/CVE-2026-26269/index.md","name":"CVE-2026-26269","record":{"aliases":["AZL-77592","AZL-77850","BELL-CVE-2026-26269","CLSA-2026-1772466351","CLSA-2026-1772622920","CLSA-2026-1772703383","CLSA-2026-1772703948","CLSA-2026-1772814085","CLSA-2026-1773141936","CLSA-2026-1773505564","CLSA-2026-1773506143","DEBIAN-CVE-2026-26269","ECHO-d50c-d5dc-4726","GHSA-9w5c-hwr9-hc68","MGASA-2026-0042","OESA-2026-1429","OESA-2026-1497","OESA-2026-1498","OESA-2026-1499","OESA-2026-1500","OESA-2026-1501","ROOT-OS-DEBIAN-12-CVE-2026-26269"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Vim text editor","requires_auth":"none","summary":"A stack buffer overflow in Vim's NetBeans integration allows a malicious server to execute arbitrary code via a crafted specialKeys command.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vim","vendor":"vim"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command.
