{"id":"CVE-2026-55697","aliases":["GHSA-gj8w-mvpf-x27x"],"url":"https://o3.security/vulnerability/CVE-2026-55697","summary":"pnpm: Repository-controlled configDependencies can select a pacquet native install engine","details":"pnpm is a package manager. Prior to 10.34.2 and 11.5.3, pnpm can install configDependencies declared in pnpm-workspace.yaml before command dispatch. Before the patch, a repository could declare pacquet or @pnpm/pacquet as a config dependency and pnpm treated that repository-controlled dependency as an install-engine opt-in. During install, pnpm resolved a platform-specific @pacquet/<platform>-<arch>/pacquet binary from node_modules/.pnpm-config/<packageName> and spawned it as the developer or CI user. This vulnerability is fixed in 10.34.2 and 11.5.3.","published":"2026-06-25T16:42:08.593Z","modified":"2026-07-15T01:49:14.795507939Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":{"score":0.00174,"percentile":0.07054,"asOf":"2026-08-11"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"pnpm","fixedVersion":"11.5.3"},{"ecosystem":"npm","name":"pnpm","fixedVersion":"11.5.3"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55697.json"},{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-gj8w-mvpf-x27x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55697"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:14.795507939Z"}}
