CVE-2026-79653 Eclipse Foundation CVE debrief

Who should care

Organizations using Eclipse SW360 with file system storage enabled should verify their configurations and consider updates or workarounds. This includes operators, platform administrators, vulnerability management teams, and security teams who need to assess the impact of this vulnerability on their systems and plan accordingly. The vulnerability can lead to arbitrary file path traversal, which could result in unauthorized access or data manipulation. Therefore, it is crucial for these teams to review their system configurations and apply necessary patches or workarounds to mitigate the risk. Additionally, defenders should monitor for potential exploitation attempts and review system logs for suspicious activity related to file system interactions. They should also ensure that their incident response plans are updated to address potential impacts of this vulnerability. Limited information is available about the scope of affected systems and vendor remediation efforts, emphasizing the need for proactive measures based on available data and source-confidence limits. Defenders should verify system configurations, track exceptions, and close items only after evidence is documented, ensuring a thorough review process. This involves confirming whether affected product deployments exist in managed environments and assigning an owner for follow-up. Compensating controls should be reviewed for exposed systems while remediation is scheduled and verified. Relevant monitoring, detection, and logs should be checked for exposed assets that need extra review. The goal is to minimize potential impact through proactive measures and thorough verification tasks based on available information and source-confidence limits. Therefore, organizations should prioritize reviewing and updating their configurations, and staying informed about vendor guidance and potential patches. This proactive approach will help in mitigating the risks associated with CVE-2026-79653 effectively. The immediate actions include verifying configurations, planning for updates or mitigations, and reviewing compensating controls. By taking these steps, organizations can enhance their security posture against潜在的

Technical summary

CVE-2026-79653 is a path traversal vulnerability in Eclipse SW360 versions 19.0.0, 19.1.0, 19.2.0, 20.0.0, and 20.1.0. When the system is configured to use file system storage with the config key enable.attachment.store.to.file.system, an attacker can manipulate filenames upon upload to cause arbitrary file path traversal. The CVSS score is 6 (MEDIUM). The immediate workaround is to disable the enable.attachment.store.to.file.system config key or update to fixed versions. Affected organizations should assess their exposure and consider applying updates or mitigations.

Defensive priority

Organizations using Eclipse SW360 with file system storage enabled should verify their configurations and consider updating to fixed versions or disabling the enable.attachment.store.to.file.system config key.

Recommended defensive actions

• Verify Eclipse SW360 configurations for file system storage and consider updates or workarounds.
• Disable the enable.attachment.store.to.file.system config key if not required.
• Monitor for fixed versions and apply them as available.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
