Is this suited for github?

  • Yes, this is suited for github

To Reproduce

See https://stackblitz.com/edit/stackblitz-starters-wsvsumaj?file=index.js (node ./index.js to start)

  1. Use Organization plugin with two custom roles, each with a single custom permission (say, role AUser has a: use-a and role BUser has b: use-b)
  2. Assign both roles to one user
  3. Call hasPermission with each permission separately - both succeed
  4. Call hasPermission on both permissions together - fails

Current vs. Expected behavior

Expected: if user has the roles that grant permission A and permission B, then hasPermission on the union of those permissions (A and B) should also succeed
Actual: hasPermission returns success === false

What version of Better Auth are you using?

1.2.9

Provide environment information

- OS: Windows 11 Build 26100
- WSL2: Linux 6.6.87.1-microsoft-standard-WSL2 
- Debian trixie

Which area(s) are affected? (Select all that apply)

Backend, Client, Package

Auth config (if applicable)

See Stackblitz repro

Additional context

I think the reason is because the permissions for the roles are checked independently, and no single role has all of the requested permissions.

The way I expected this to work is that the permissions for all the roles are gathered first, and then those permissions are checked against the requested permissions.

Hi, @harveylee. I'm Dosu, and I'm helping the better-auth team manage their backlog and am marking this issue as stale.

Issue Summary

  • You reported that the hasPermission function in Better Auth v1.2.9 returns false when checking multiple permissions granted across different roles.
  • The problem occurs because the function checks permissions per role instead of aggregating them across all roles.
  • You provided a Stackblitz reproduction to demonstrate the issue.
  • There have been no further comments or updates on this issue.

Next Steps

  • Please let me know if this issue is still relevant with the latest version of better-auth by commenting here to keep the discussion open.
  • Otherwise, this issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!

Still occurs in 1.3.9. I updated the Stackblitz repro (still at https://stackblitz.com/edit/stackblitz-starters-wsvsumaj?file=index.js)
