Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Stored cross-site scripting (XSS) vulnerability in the Wiki widget in Liferay Portal 7.1.0 through 7.4.3.87, and Liferay DXP 7.0 fix pack 83 through 102, 7.1 fix pack 28 and earlier, 7.2 fix pack 20 and earlier, 7.3 update 33 and earlier, and 7.4 before update 88 allows remote attackers to inject arbitrary web script or HTML into a parent wiki page via a crafted payload injected into a wiki page's ‘Content’ text field.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.
