CVE-2022-26136 is a vulnerability affecting multiple Atlassian products in which a remote, unauthenticated attacker can bypass Servlet Filters used by first-party and third-party applications. Because these filters are commonly relied upon to enforce security controls such as authentication checks and request handling restrictions, bypassing them can allow requests to reach application functionality without the intended validation or protection. The precise downstream effect varies by product, version, installed apps, and the specific filters in use, but documented consequences include authentication bypass and cross-site scripting. Affected products include Atlassian Bamboo, Bitbucket, Confluence, Crowd, Fisheye/Crucible, Jira, and Jira Service Management across multiple version ranges.
