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-2026-57451 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-2026-57451/ (Markdown: https://insights.sbomify.com/CVE-2026-57451/index.md)","id":"CVE-2026-57451","markdown":"https://insights.sbomify.com/CVE-2026-57451/index.md","name":"CVE-2026-57451","record":{"aliases":["ALPINE-CVE-2026-57451","AZL-91116","BELL-CVE-2026-57451","DEBIAN-CVE-2026-57451","ECHO-f07e-8df7-39f4","GHSA-f36c-2qcp-7gpw","MINI-vvg5-xfr4-6688"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Vim text editor","requires_auth":"none","summary":"An attacker can cause a crash in Vim by providing a crafted undo file that triggers an out-of-bounds read due to unchecked property counts.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vim","vendor":"vim"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Vim is an open source, command line text editor. Prior to 9.2.0670, get_text_props() in src/textprop.c reads a uint16 property count stored inline after a line's text and returns it as the number of 32-byte textprop_T entries that follow. The only check is a floor that guarantees room for a single entry; the count is never checked against the amount of data actually present. A line that declares a large count while carrying little data causes consumers to read far past the end of the line buffer. Such a line can be delivered through a crafted undo file, leading to a crash. This vulnerability is fixed in 9.2.0670.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Vim: Out-of-bounds Read in Text Property Count","id":"CVE-2026-57451","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"vim:vim","products":["vim:vim"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Vim: Out-of-bounds Read with libsodium-encrypted Files","id":"CVE-2026-57452"},"packages":[],"prev":{"headline":"Actual Sync Server: CORS Proxy GitHub API Allowlist Prefix Bypass Leaks Private Repositories Through the Server GitHub Token","id":"CVE-2026-57449"},"products":["vim"],"published":"2026-06-25","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-20703","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-6349","kev_date_added":null,"published":"2017-02-27"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-6350","kev_date_added":null,"published":"2017-02-27"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-5953","kev_date_added":null,"published":"2017-02-10"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-3075","kev_date_added":null,"published":"2009-02-21"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-3076","kev_date_added":null,"published":"2009-02-21"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-6235","kev_date_added":null,"published":"2009-02-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-25","vendors":["vim"]},"summary":"An attacker can cause a crash in Vim by providing a crafted undo file that triggers an out-of-bounds read due to unchecked property counts.","url":"https://insights.sbomify.com/CVE-2026-57451/"}
