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-2026-112945/ (Markdown: https://insights.sbomify.com/CVE-2026-112945/index.md)","id":"CVE-2026-112945","markdown":"https://insights.sbomify.com/CVE-2026-112945/index.md","name":"CVE-2026-112945","record":{"aliases":["ECHO-2b64-1afa-7929","GHSA-9jrq-w75r-8gcw","UBUNTU-CVE-2026-112945"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"Vite is a frontend tooling framework for JavaScript. Prior to 6.4.4, 7.3.7, 8.1.6, 8.2.4, and 8.3.3, applications using custom middleware are vulnerable when they pass an unchanged browser request URL to server.transformIndexHtml. getHtmlFilename uses the query-bearing request URL to resolve an existing local file while preserving attacker-supplied leading slashes in the generated proxy module URL. If the transformed HTML contains an inline module script and a victim browser loads the crafted development-server page, the leading double slash makes the browser fetch and execute an attacker-controlled module in the Vite-served page. This execution can expose sensitive page data or permit critical actions available to the affected application. This issue is fixed in versions 6.4.4, 7.3.7, 8.1.6, 8.2.4, and 8.3.3.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Vite: Cross origin script execution through Vite custom middleware","id":"CVE-2026-112945","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":12,"n_references":3,"next":{"headline":"Vite: Files outside `server.fs.allow` could be served when project paths match system paths on non-Windows machine","id":"CVE-2026-112946"},"packages":[{"ecosystem":"npm","fixed":["6.4.4"],"introduced":["0"],"last_affected":[],"package":"vite","purl":null,"source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["6.4.4"],"introduced":["0"],"last_affected":[],"package":"vite","purl":"pkg:npm/vite","source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["7.3.7"],"introduced":["7.0.0"],"last_affected":[],"package":"vite","purl":null,"source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["7.3.7"],"introduced":["7.0.0"],"last_affected":[],"package":"vite","purl":"pkg:npm/vite","source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["8.1.6"],"introduced":["8.0.0"],"last_affected":[],"package":"vite","purl":null,"source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["8.1.6"],"introduced":["8.0.0"],"last_affected":[],"package":"vite","purl":"pkg:npm/vite","source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["8.2.4"],"introduced":["8.2.0"],"last_affected":[],"package":"vite","purl":null,"source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["8.2.4"],"introduced":["8.2.0"],"last_affected":[],"package":"vite","purl":"pkg:npm/vite","source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["8.3.3"],"introduced":["8.3.0"],"last_affected":[],"package":"vite","purl":null,"source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["8.3.3"],"introduced":["8.3.0"],"last_affected":[],"package":"vite","purl":"pkg:npm/vite","source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["1.1.0"],"introduced":["0"],"last_affected":[],"package":"vite-plus","purl":null,"source":"GHSA-9jrq-w75r-8gcw"},{"ecosystem":"npm","fixed":["1.1.0"],"introduced":["0"],"last_affected":[],"package":"vite-plus","purl":"pkg:npm/vite-plus","source":"GHSA-9jrq-w75r-8gcw"}],"prev":{"headline":"launch-editor: Editor CLI flag misinterpretation causing arbitrary command execution for some editors","id":"CVE-2026-112944"},"products":["vite","vite-plus"],"published":"2026-10-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["vitejs"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-112945/"}
