This pull request addresses an issue where the BackupEligible flag could be inadvertently altered during the login validation process. The following changes have been made:

  • Added a check in the validateLogin function to ensure that the BackupEligible flag remains consistent.
  • If the BackupEligible flag is found to be altered, an error is returned.
  • Updated the validateLogin function to handle this validation step appropriately.

Walkthrough

The recent update introduces a critical validation step in the WebAuthn login process to ensure the integrity of the BackupEligible flag. This enhancement in webauthn/login.go strengthens the security of the login mechanism by verifying the flag's consistency before proceeding with other updates.

Changes

File Change Summary
webauthn/login.go Added a check for the BackupEligible flag to validate its stability before updating other flags based on response data.

A rabbit hops through lines of code,
Ensuring flags don't shift or erode.
With every hop, security grows,
As BackupEligible status shows.
In fields of data, safe and sound,
The login's trust is tightly bound.
🐇✨

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Since go-webauthn v0.11.0, the backup eligibility flag is strictly validated, but Miniflux does not store this flag.

This workaround to set the flag based on the parsed response, and avoid "BackupEligible flag inconsistency detected during login validation" error.

See go-webauthn/webauthn#240
