{"id":"CVE-2021-32770","aliases":["GHSA-rqjw-p5vr-c695"],"url":"https://o3.security/vulnerability/CVE-2021-32770","summary":"Basic-auth app bundle credential exposure in gatsby-source-wordpress","details":"### Impact\nThe gatsby-source-wordpress plugin prior to versions 4.0.8 and 5.9.2 leaks .htaccess HTTP Basic Authentication variables into the app.js bundle during build-time.  Users who are not initializing basic authentication credentials in the gatsby-config.js are not affected.\n\nExample affected gatsby-config.js:\n```\n      resolve: 'gatsby-source-wordpress',\n        auth: {\n          htaccess: {\n            username: leaked_username\n            password: leaked_password,\n          },\n        },\n```\n\n### Patches\nA patch has been introduced in gatsby-source-wordpress@4.0.8 and gatsby-source-wordpress@5.9.2 which mitigates the issue by filtering all variables specified in the `auth: { }` section.  Users that depend on this functionality are advised to upgrade to the latest release of gatsby-source-wordpress, run `gatsby clean` followed by a `gatsby build`.\n\n\n### Workarounds\nThere is no known workaround at this time, other than manually editing the app.js file post-build.\n\n\n### For more information\nEmail us at [security@gatsbyjs.com](mailto:security@gatsbyjs.com)","published":"2021-07-15T19:15:07.920Z","modified":"2026-07-09T14:06:26.402491Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"gatsby-source-wordpress","fixedVersion":"4.0.8"},{"ecosystem":"npm","name":"gatsby-source-wordpress","fixedVersion":"5.9.2"}],"fix":null,"references":[{"type":"EVIDENCE","url":"https://github.com/gatsbyjs/gatsby/security/advisories/GHSA-rqjw-p5vr-c695"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32770"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T14:06:26.402491Z"}}
