Description

Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.6, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.16 and 7.4 GA through update 92 allow any authenticated user to modify the content of emails sent through the calendar portlet, allowing an attacker to send phishing emails to any other user in the same organization.

Liferay Portal is fixed on the master branch from commit ff18e7d.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.calendar.service. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update com.liferay:com.liferay.calendar.service to 6.0.83 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7mxq-h2r7-h449 is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-7mxq-h2r7-h449 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-7mxq-h2r7-h449. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
