MediumCVSS 5.4 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.58% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: com.liferay:com.liferay.frontend.js.web (Maven) 5.0.0; com.liferay.portal:release.dxp.bom (Maven) 7.3.10.fp2; com.liferay.portal:release.portal.bom (Maven) 7.3.7-ga8.

Low priority for now. Upgrade to com.liferay:com.liferay.frontend.js.web (Maven) 5.0.0; com.liferay.portal:release.dxp.bom (Maven) 7.3.10.fp2; com.liferay.portal:release.portal.bom (Maven) 7.3.7-ga8 or later.
