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-2026-121745/ (Markdown: https://insights.sbomify.com/CVE-2026-121745/index.md)","id":"CVE-2026-121745","markdown":"https://insights.sbomify.com/CVE-2026-121745/index.md","name":"CVE-2026-121745","record":{"aliases":["GHSA-h3c2-g6gc-6cgx"],"analysis":null,"analysis_generated_by":null,"assigner":"harborist","cpe":[],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-214","name":"Invocation of Process Using Visible Sensitive Information"}],"description":"Node Version Manager (nvm) is a POSIX-compliant shell function for managing multiple node.js versions. In versions 0.40.0 through 0.40.8, when `NVM_AUTH_HEADER` is set, `nvm_download` passes the credential to curl or wget as a `--header \"Authorization: ...\"` command-line argument. Process arguments are visible to every local user (on Linux via `ps` or `/proc//cmdline` unless `/proc` is mounted with `hidepid=`; on macOS via `ps`), so another unprivileged account on the same machine can read the token while nvm is downloading during `nvm ls-remote`, `nvm install`, and similar commands, and gain whatever access it grants on the private mirror. Only users who set `NVM_AUTH_HEADER` on a host shared with other local accounts are affected. Version 0.41.0 passes the header to curl on stdin and to GNU Wget in a private temporary config file. BusyBox wget reads no config file, so when it is the only downloader available the header is still passed as an argument.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"nvm exposes NVM_AUTH_HEADER to other local users on the curl/wget command line","id":"CVE-2026-121745","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"nvm use --save and nvm install --save write through a symlinked .nvmrc, overwriting any file the user can write","id":"CVE-2026-121746"},"nickname":null,"packages":[],"prev":{"headline":"Ashlar-Vellum Cobalt XE File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2026-121744"},"products":["nvm"],"published":"2026-11-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-11-09","vendors":["nvm-sh"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-121745/"}
