{"id":"CVE-2026-55180","aliases":["GHSA-3qhv-2rgh-x77r"],"url":"https://o3.security/vulnerability/CVE-2026-55180","summary":"pnpm: Repository config can expand victim environment secrets into registry requests before scripts run","details":"pnpm is a package manager. Prior to 10.34.2 and 11.5.3, pnpm and pacquet expanded ${ENV_VAR} placeholders from repository-controlled .npmrc and pnpm-workspace.yaml into registry request destinations and registry credentials. A malicious repository could cause dependency resolution to send victim environment secrets to an attacker-selected registry before lifecycle scripts run. This vulnerability is fixed in 10.34.2 and 11.5.3.","published":"2026-06-25T17:00:35.752Z","modified":"2026-08-12T03:51:29.230698800Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},"epss":{"score":0.00366,"percentile":0.29721,"asOf":"2026-09-07"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"pnpm","fixedVersion":"10.34.2"},{"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-2026-55180.json"},{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-3qhv-2rgh-x77r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55180"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.230698800Z"}}
