I was able to disable the clickjacking in JIRA and Confluence based on the official documentation but I couldn't find any such way to disable it in Bamboo. Any ideas on how to achieve it?
Thanks for bringing this up. Unfortunately, there is no straightforward option to disable these clickjacking headers in Bamboo (like Jira or Confluence) that was introduced in Bamboo 5.14.
Considering that this can be a good feature, I have created one on your behalf here: BAM-20788. Could you also please share your use case on why disabling this option is necessary?
Please feel free to upvote and follow the progress there.
