Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Reflected cross-site scripting in the com.liferay.journal.web package before version 5.0.196 lets an authenticated user inject JavaScript through the backURL parameter, affecting Liferay Portal 7.4.3.132 and Liferay DXP 2025.Q2.0 through 2025.Q2.8 and 2025.Q1.0 through 2025.Q1.15. An attacker would need a logged-in account and would have to get a victim to open a crafted link, after which the script runs in the victim's browser. Upgrade the com.liferay.journal.web package to version 5.0.196 or later. The source gives no other workaround.
