Name of the Vulnerable Software and Affected Versions gatsby-source-wordpress versions prior to 4.0.8 and 5.9.2

Description The gatsby-source-wordpress plugin leaks .htaccess HTTP Basic Authentication variables into the app.js bundle during build-time. This issue affects users who initialize basic authentication credentials in the gatsby-config.js. A patch has been introduced to mitigate the issue by filtering all variables specified in the auth: { } section.

Recommendations For versions prior to 4.0.8, upgrade to gatsby-source-wordpress@4.0.8, run gatsby clean followed by a gatsby build. For versions prior to 5.9.2, upgrade to gatsby-source-wordpress@5.9.2, run gatsby clean followed by a gatsby build. As a temporary workaround, consider manually editing the app.js file post-build to remove leaked credentials.
