Remote code execution via REST command injection

Published Aug 25, 2022 · Updated Oct 21, 2025

Command injection in Atlassian Bitbucket Server and Data Center 7.0.0 through 8.3.0 allows remote attackers to execute arbitrary code. The repository archive endpoint accepts null bytes in its prefix parameter, allowing injected --exec arguments to reach git archive. Access to a public repository, or read permission on a private repository, is required; injected commands run in the service context.
