    Member users were able to retrieve Channel secret because of a bug (resolved)

    We discovered and fixed a bug in the LINE Developers console that allowed Member users to obtain a channel secret. We sincerely apologize for any inconvenience caused.

    On July 24, 2019, we emailed this information to all administrators of channels with Member users.

    Issue time

    Issue inception: September 21, 2017

    Issue solved: July 17, 2019

    Details

    There was a bug that allowed Member users to obtain the channel secret, which should have appeared only to Admin users.

    The Channel settings tab did not display the channel secret when a Member user viewed the page. However, the API that the LINE Developers console called in the background did return the channel secret. Therefore, a malicious Member user could have obtained and abused the channel secret.

    tip What is a channel secret?

    The channel secret is a secret key provided by LINE to call our APIs and validate identities. It should be kept secret from unauthorized parties.

    tip Member user permissions

    Originally, Member users can only view basic information and statistics for a channel. They don't have access to the channel secret.

    What you should do

    If you're concerned that unauthorized Member users have obtained your channel secret, you should issue a new one. Doing so will invalidate the previous channel secret.

    After you issue a new channel secret, you'll have to update it in the app which uses the channel secret. Carefully consider the impact of issuing a new channel secret on your app.

    How to issue a new channel secret

    You can issue a new channel secret on the Channel settings tab in the LINE Developers console.

    tip Forced reissue of channel secret

    LINE will not forcibly reissue new channel secrets. The Admin user for each channel should decide whether it's necessary to reissue a new channel secret.

    Acknowledgement

    This bug was reported through the LINE Security Bug Bounty Program.

    LINE will continue to improve the quality of its services to prevent future outages. Thank you for your understanding.

    Notice of problems with migration of LINE official accounts (resolved)

    We encountered problems during the planned migration of accounts from the deprecated Developer Trial plan to the new free plan, which started on June 11, 2019. The problems have now been resolved. We sincerely apologize for the inconvenience this caused.

    Date and time of outage

    From: June 11, 2019
    Until: June 18, 2019 14:33 JST(GMT+9)

    Cause

    In Japan and Thailand, accounts that were migrated from the old Developer Trial plan to the new free plan incorrectly retained their old limit on number of friends (50).

    Details

    When a user tried to befriend an account that had reached the limit of 50 friends, this error was displayed:

    Sorry, the account you are trying to add cannot accept any more friends.

    We have now removed the limit on the number of friends.
