{"id":"CVE-2025-48069","aliases":["GHSA-2c47-m757-32g6","GO-2025-3702"],"url":"https://o3.security/vulnerability/CVE-2025-48069","summary":"ejson2env has insufficient input sanitization","details":"### Summary\nThe `ejson2env` tool has a vulnerability related to how it writes to `stdout`. Specifically, the tool is intended to write an export statement for environment variables and their values. However, due to inadequate output sanitization, there is a potential risk where variable names or values may include malicious content, resulting in additional unintended commands being output to `stdout`. If this output is improperly utilized in further command execution, it could lead to command injection vulnerabilities, allowing an attacker to execute arbitrary commands on the host system.\n\n### Details\nThe vulnerability exists because environment variables are not properly sanitized during the decryption phase, which enables malicious keys or encrypted values to inject commands.\n\n### Impact\nAn attacker with control over  `.ejson` files can inject commands in the environment where `source $(ejson2env)`  or `eval ejson2env` are executed.\n\n\n### Mitigation\n- Update to a version of `ejson2env` that sanitizes the output during decryption or\n- Do not use `ejson2env` to decrypt untrusted user secrets or\n- Do not evaluate or execute the direct output from `ejson2env` without removing nonprintable characters.\n\n### Credit\nThanks to security researcher [Demonia](https://hackerone.com/demonia?type=user) for reporting this issue.","published":"2025-05-21T17:43:43.680Z","modified":"2026-08-12T03:51:24.265931892Z","cvss":{"score":6.6,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.01317,"percentile":0.69164,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/Shopify/ejson2env/v2","fixedVersion":"2.0.8"},{"ecosystem":"Go","name":"github.com/Shopify/ejson2env","fixedVersion":null},{"ecosystem":"RubyGems","name":"ejson2env","fixedVersion":"2.0.8"}],"fix":{"url":"https://github.com/Shopify/ejson2env/commit/592b3ceea967fee8b064e70983e8cec087b6d840","label":"Shopify/ejson2env@592b3ce"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48069.json"},{"type":"ADVISORY","url":"https://github.com/Shopify/ejson2env/security/advisories/GHSA-2c47-m757-32g6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48069"},{"type":"FIX","url":"https://github.com/Shopify/ejson2env/commit/592b3ceea967fee8b064e70983e8cec087b6d840"},{"type":"PACKAGE","url":"https://github.com/Shopify/ejson2env"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/ejson2env/CVE-2025-48069.yml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.265931892Z"}}
