{“lastseen”:””,”description”:”nvm (Node Version Manager) through 0.40.4 executes arbitrary commands from version strings supplied by the configured Node.js\/io.js mirror. Commands such as `nvm install` read the available versions from the mirror’s index.tab and use the selected version, without sanitization, to build download URLs and shell\/awk commands. Two sinks are affected by the same untrusted input: nvm_download() built a curl\/wget command string and ran it with `eval`, so a version field containing command substitution (for example $(id)) was executed by the local shell; and nvm_get_checksum() interpolated the version-derived download slug into an awk program, so a crafted version could execute arbitrary commands via awk’s system(). An attacker who controls the configured mirror, supplies mirror content to a user or CI on a non-default mirror, or machine-in-the-middles a non-TLS mirror can \u2234 run arbitrary commands with the privileges of the user running nvm. The default mirror (https:\/\/nodejs.org over TLS) is not affected. Fixed on master (pending the next tagged release) by passing every argument as a literal argv element instead of using eval, by passing the value to awk as data via -v instead of interpolating it into the program, and by rejecting any version outside the Node.js\/io.js version grammar before it is used.”,”published”:”2026-06-04T17:02:23.805Z”,”modified”:”2026-06-04T18:11:18.108Z”,”type”:”cve”,”title”:”nvm executes commands from a malicious Node.js mirror’s version strings”,”source”:”openjs”,”references”:”https:\/\/github.com\/nvm-sh\/nvm\/security\/advisories\/GHSA-3c52-35h2-gfmm\\nhttps:\/\/github.com\/nvm-sh\/nvm\/commit\/6d870d182cd5333647ffa16c0d7dbcd817ec27a8\\nhttps:\/\/github.com\/nvm-sh\/nvm\/commit\/90bb88748ba6c29c2cec73b18ed7057413aef308\\nhttps:\/\/github.com\/nvm-sh\/nvm\/commit\/70fb4ede6b9731d75d86451d48caa5faffbec21c”,”id”:”CVE-2026-10796″,”bulletinFamily”:””,”cwe”:[“CWE-78″],”cvelist”:null,”sourceData”:”nvm-sh nvm 0″,”sourceHref”:””,”cvss”:{“score”:7.5,”severity”:”HIGH”,”vector”:”CVSS:4.0\/AV:N\/AC:L\/AT:P\/PR:N\/UI:A\/VC:H\/VI:H\/VA:H\/SC:N\/SI:N\/SA:N”,”version”:”4.0″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”nvm”,”version”:”0″,”vendor”:”nvm-sh”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
