Workaround

Workaround 1
The URL validation can be disabled but it comes with increased security risk as you're also disabling an XSS check.

Evaluate whether you want to or are able to use the workaround to disable URL validation which would enable a potential XSS in the Webhook notification URL that allows a user with edit plan permission to inject malicious code into that field.

-Dbamboo.notifications.webhook.url.xss.check=false

• Configuring your system properties

Workaround 2
Only applicable if the Bamboo variable you're trying to use is for the GitHub build status API. If so, please consider upgrading to Bamboo 10 which has native GitHub build status integration:
