The Github repository importer in Atlassian Bitbucket Server before version 5.3.0 allows remote attackers to determine if a service they could not otherwise reach has open ports via a Server Side Request Forgery (SSRF) vulnerability.

Security readout for executives and security teams

Older Atlassian Bitbucket Server versions had an SSRF flaw in the GitHub repository importer. An attacker could use the server as a probe to learn whether otherwise unreachable services had open ports. The sources do not show data theft or code execution, but internal network discovery can support later attacks. Exposure is limited to Atlassian Bitbucket Server installations running versions earlier than 5.3.0, especially where the GitHub repository importer is accessible to remote users. Treat this as a cleanup priority for legacy Bitbucket Server. It is not confirmed as exploited, but it can expose internal network information and should be remediated during normal vulnerability management. Mitigation focus: Upgrade Bitbucket Server to version 5.3.0 or later.; Review Atlassian BSERV-10591 for vendor remediation details.; Restrict access to repository import features where operationally possible..

CWE-918: Information exposure and cloud metadata lookup

Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.

Server-Side Request Forgery (SSRF)

Server-Side Request Forgery (SSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
