Bitbucket Cloud and Jenkins OSS Webhook

Hello,

We are currently in migration phase of Atlassian on-prem to Cloud env. We are in the process of migrating Bitbucket to Cloud environment.

We use Jenkins OSS version and is currently at 2.462.1. The Bitbucket plugin we have is 241.v6d24a_57f9359. We are constantly getting 500 response on the Bitbucket Webhooks logs.

Just to add on, we are seeing the below messages on the logs:
When using webhook secrets, verify the HMAC signature by using the raw webhook otherwise the signatures will not match. We do not have any secrets created. Tried with empty secret as well but no luck!

Any recommendations and suggestions will greatly help me.

Jenkins 2.462.1 was released in August 2024. It is approaching two years old. The Jenkins update center stopped providing update metadata for that release almost a year ago. There are multiple security advisories published that disclose issues in that release. You should upgrade to a current Jenkins release.

Bitbucket plugin 241.v6d24a_57f9359 was released 3 years ago. Many releases have happened since that release.

Unfortunately, I don’t have any specific hints to offer for the HTTP 500 response that you are receiving. The open issue list does not mention anything related. You might check the list of all issues in case something is visible there.
