CVE-2019-15000: The commit diff rest endpoint in Bitbucket Server and Data Center before 5.16.10 (the fixed version for 5.1...

Security readout for executives and security teams

A vulnerable Bitbucket Server/Data Center instance can let someone with repository access abuse the commit diff API to read host files and execute commands. If a project or repository allows public access, the issue may be reachable anonymously. This is serious for source-code hosting because compromise can expose code, credentials, and the server itself. Exposure is limited to Atlassian Bitbucket Server and Data Center versions before the listed fixed releases. Internet-facing or publicly accessible repositories increase risk because exploitation may not require authentication when public project or repository access is enabled. Treat this as urgent for any self-managed Bitbucket instance, especially internet-facing deployments. The impact includes possible server command execution and source-code exposure. Prioritize upgrade and public-access review before routine maintenance work. Mitigation focus: Upgrade to the fixed Bitbucket release for the deployed version line.; Fixed lines include 5.16.10, 6.0.10, 6.1.8, 6.2.6, 6.3.5, 6.4.3, and 6.5.2.; Disable public project or repository access where it is not required..
