Summary

The Comments plugin for Grav CMS through version 1.2.10 registers an admin handler that returns comment data as JSON without any authentication check. The handler branches on isAdmin(), which only indicates that the admin service is registered on the current route rather than that the visitor is authenticated. On a site using the classic Admin plugin with Comments enabled, an unauthenticated remote attacker can request /admin/comments/page:<n> and retrieve every comment from the last 7 days, including each commenter's email address and the absolute server filesystem path of the data file.

Risk Assessment

Leakage of commenters' email addresses and filesystem paths may violate user privacy and reveal server structure information. This may facilitate further targeted attacks.

Recommendation

Update the Comments plugin to version 1.2.11 or later. Review access logs for unauthorized requests to /admin/comments/.

Original NVD description (English source)

The Comments plugin (getgrav/grav-plugin-comments) for Grav CMS through version 1.2.10 registers an admin handler that returns comment data as JSON without any authentication check. The handler branches on isAdmin(), which only indicates that the admin service is registered on the current route rather than that the visitor is authenticated, and it echoes the JSON and calls exit() during the plugins stage, before the classic Admin plugin would render its login screen. On a site using the classic Admin plugin with Comments enabled (the default), an unauthenticated remote attacker can request /admin/comments/page:<n> (e.g. page:0.001) and retrieve every comment from the last 7 days, including each commenter's email address and the absolute server filesystem path of the data file. Sites running the Grav 2.0 Admin Next stack (admin2 + api) are not affected via this path. The issue is fixed in 1.2.11, which requires an authenticated user with admin.comments or admin.super and removes the absolute filePath from the response.
