Description
Severity: medium (5.8) / important
Server-Side Request Forgery (SSRF), Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Apache Druid.
This issue affects all previous Druid versions.
When using the Druid management proxy, a request that has a specially crafted URL could be used to redirect the request to an arbitrary server instead. This has the potential for XSS or XSRF. The user is required to be authenticated for this exploit. The management proxy is enabled in Druid's out-of-box configuration. It may be disabled to mitigate this vulnerability. If the management proxy is disabled, some web console features will not work properly, but core functionality is unaffected.
Users are recommended to upgrade to Druid 31.0.2 or Druid 32.0.1, which fixes the issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.druid:druid, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.apache.druid:druid to 31.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-27888 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-27888 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-27888. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

- Apache Druid - Server-Side Request Forgery
- Severity
- high
- Impact
- Authenticated attackers can exploit SSRF vulnerabilities through the management proxy to redirect requests to arbitrary servers, potentially enabling XSS, XSRF attacks, or accessing internal services.
- Remediation
- Upgrade to Apache Druid version 31.0.2 or 32.0.1, or disable the management proxy to mitigate this vulnerability.
