Progress MarkLogic Server: Server-side request forgery in Azure deployments
Summary
MarkLogic Server deployments on Microsoft Azure contain a server-side request forgery (SSRF) vulnerability. An authenticated attacker can make the server send requests to internal cloud services, which may lead to unauthorized access to cloud credentials or tokens. The CNA rates the issue CVSS 8.5 (High); the impact is limited to Azure deployments, and the attacker needs a valid account.
Affected
- Progress MarkLogic Server 11.0.0 to before 11.3.7 on Azure
- Progress MarkLogic Server 12.0.0 to before 12.1.0 on Azure
- Press reports list a narrower range (12.0 to 12.0.3 and 11.0 to 11.3.6); treat any build below the fixed versions as affected until the vendor bulletin is checked
Fixed in
- 11.3.7
- 12.1.0
Workaround
- Vendor: none named for this CVE.
- Restrict outbound traffic from the MarkLogic host to internal Azure metadata and management endpoints (third-party suggestion, not a vendor fix).
Exploitation
- CISA SSVC: exploitation none, automatable no, technical impact partial.
- No known exploitation in the wild; not listed in CISA KEV.
- No public proof of concept found.
- EPSS 0.0019 (very low).
Our recommendation
- Identify whether MarkLogic Server runs on Azure, including instances installed by partners.
- Upgrade to 11.3.7 or 12.1.0 as part of the October 2026 vendor bulletin, which covers several related flaws.
- Restrict egress from the database host to Azure metadata and management endpoints.
- If the host may have been abused, rotate cloud credentials and managed-identity tokens.
- Verify whether the MarkLogic endpoint is reachable from the internet.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
