CVE-2021-33334

Liferay Portal and Liferay DXP Fails to Properly Check User Permissions

The Dynamic Data Mapping module in Liferay Portal 7.0.0 through 7.3.2, and Liferay DXP 7.0 before fix pack 94, 7.1 before fix pack 19, and 7.2 before fix pack 6, does not properly check user permissions, which allows remote attackers with the forms "Access in Site Administration" permission to view all forms and form entries in a site via the forms section in site administration.

CVE-2021-33334 has a CVSS score of 4.3 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (7.0.10.fp94, 7.1.10.fp19, 7.2.10.fp6); upgrading removes the vulnerable code path.

2. How severe is CVE-2021-33334? CVE-2021-33334 has a CVSS score of 4.3 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2021-33334?
   • com.liferay.portal:release.portal.bom (maven) (versions >= 7.0.0, <= 7.3.2)
   • com.liferay.portal:release.dxp.bom (maven) (versions >= 7.0.10.fp0, < 7.0.10.fp94)
4. Is there a fix for CVE-2021-33334? Yes. CVE-2021-33334 is fixed in 7.0.10.fp94, 7.1.10.fp19, 7.2.10.fp6. Upgrade to this version or later.
5. Is CVE-2021-33334 exploitable, and should I be worried? Whether CVE-2021-33334 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2021-33334 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2021-33334?
   • Upgrade com.liferay.portal:release.dxp.bom to 7.0.10.fp94 or later
   • Upgrade com.liferay.portal:release.dxp.bom to 7.1.10.fp19 or later
   • Upgrade com.liferay.portal:release.dxp.bom to 7.2.10.fp6 or later
