How severe is CVE-2023-44311?

CVE-2023-44311 has a CVSS score of 6.1/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-44311?

CVE-2023-44311 affects the following packages: com.liferay:com.liferay.oauth2.provider.rest (Maven), com.liferay.portal:release.dxp.bom (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-44311?

Update com.liferay:com.liferay.oauth2.provider.rest to 4.0.51 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-44311 is resolved across your whole dependency graph.

How do I detect CVE-2023-44311 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.oauth2.provider.rest, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-44311 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2023-44311 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-44311 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-2023-44311?

CVE-2023-44311 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 47th 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

Multiple reflected cross-site scripting (XSS) vulnerabilities in the Plugin for OAuth 2.0 module's OAuth2ProviderApplicationRedirect class before 4.0.51 from Liferay Portal (7.4.3.41 through 7.4.3.89), and Liferay DXP 7.4 update 41 through update 89 allow remote attackers to inject arbitrary web script or HTML via the (1) code, or (2) error parameter. This issue is caused by an incomplete fix in CVE-2023-33941.
