CORS Bypass Vulnerability in Atlassian Products

CVE-2022-26137

What is CVE-2022-26137?

A vulnerability in multiple Atlassian products enables a remote attacker to exploit Cross-origin resource sharing (CORS) by sending specially crafted HTTP requests. This can result in unauthorized access to vulnerable applications, permitting the attacker to utilize the permissions of a tricked user who visits a malicious URL. Affected versions of products, including Bamboo, Bitbucket, Confluence, Crowd, Fisheye, Crucible, Jira, and Jira Service Management, must be updated to mitigate this risk.
