This Medium severity ACE (Arbitrary Code Execution) vulnerability was introduced in version 4.2.8 of Sourcetree for Mac. This ACE (Arbitrary Code Execution) vulnerability, with a CVSS Score of 5.9, allows a locally authenticated attacker to execute arbitrary code which has high impact to confidentiality, high impact to integrity, high impact to availability, and requires user interaction. Atlassian recommends that Sourcetree for Mac users upgrade to the latest version. If you are unable to do so, upgrade your instance to one of the specified supported fixed versions. See the release notes https://www.sourcetreeapp.com/download-archives . You can download the latest version of Sourcetree for Mac from the download center https://www.sourcetreeapp.com/download-archives . This vulnerability was found through the Atlassian Bug Bounty Program by Karol Mazurek (AFINE).
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.3, requiring local system access to exploit with relatively low complexity though user interaction is required requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from atlassian organizations running these solutions should prioritize assessment and patching.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For atlassian's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
