How severe is CVE-2025-43763?

CVE-2025-43763 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2025-43763?

CVE-2025-43763 affects the following packages: com.liferay:com.liferay.object.service (Maven). Ecosystems affected: Maven.

How do I fix CVE-2025-43763?

Update com.liferay:com.liferay.object.service to 1.0.208 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-43763 is resolved across your whole dependency graph.

How do I detect CVE-2025-43763 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.object.service, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-43763 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is CVE-2025-43763 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-43763 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-43763?

CVE-2025-43763 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 9th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Description

A server-side request forgery (SSRF) vulnerability exist in the Liferay Portal 7.4.0 through 7.4.3.131, and Liferay DXP 2024.Q4.0 through 2024.Q4.7, 2024.Q3.0 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13 and 2024.Q1.1 through 2024.Q1.20 that affects custom object attachment fields. This flaw allows an attacker to manipulate the application into making unauthorized requests to other instances, creating new object entries that link to external resources.
