Security readout for executives and security teams
Plain-English summary
CVE-2019-10100 affects older JetBrains YouTrack Confluence plugin versions. A user who could add an Issue macro to a Confluence page could abuse template handling to run code on the server. This is primarily urgent for organizations still running the plugin before 1.8.1.3.
Executive priority
Treat as a targeted remediation item, not a broad internet emergency. Prioritize quickly if Confluence is business-critical, the plugin is installed, and many users can edit pages or add macros.
Technical view
The issue is server-side template injection in JetBrains YouTrack Confluence plugin versions before 1.8.1.3. The CVE describes abuse of an Issue macro using a valid id field and crafted link-text-template content, resulting in remote code execution. No CVSS, CWE, or detailed affected CPE data is provided in the bundle.
Likely exposure
Exposure is likely limited to Confluence deployments using the JetBrains YouTrack Confluence plugin before version 1.8.1.3, especially where untrusted or broadly privileged users can add Issue macros to pages.
Exploitation context
The source bundle does not show KEV listing or cited evidence of active exploitation. Public details indicate exploitation requires Confluence page edit capability, macro insertion, a valid id field, and malicious template content.
Researcher notes
Evidence is sparse: the bundle contains the CVE description, JetBrains bulletin reference, and no CVSS/CWE detail. The key research questions are installed plugin version, macro permissions, affected page inventory, and whether logs show suspicious Issue macro changes.
Mitigation direction
- Inventory Confluence instances for the JetBrains YouTrack Confluence plugin.
- Check whether any installed version is before 1.8.1.3.
- Review JetBrains guidance and upgrade affected plugin installations accordingly.
- Restrict Confluence page editing and macro creation to trusted users.
- Review existing Issue macros in high-risk spaces.
Validation and detection
- Confirm plugin name and version from Confluence administration records.
- Identify pages containing YouTrack Issue macros.
- Review audit logs for suspicious macro edits before remediation.
- Verify user groups allowed to edit pages and add macros.
- Document whether version 1.8.1.3 or later is deployed.
