AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L
Authenticated Subscriber (PR:L) submits stored XSS triggered when a victim views it (UI:R); cross-context execution gives S:C with low C/I, but availability impact is not realistic for XSS so A:N.

Subscriber Cross Site Scripting (XSS) in wpForo Forum <= 3.1.5 versions.
AnalysisAI
Stored cross-site scripting in wpForo Forum 3.1.5 and earlier lets an authenticated Subscriber-level user inject script that runs in a moderator or administrator's browser when they view the crafted forum content. Exploitation requires a registered account on a WordPress site with the plugin and open registration, plus victim interaction; it does not provide direct server access or unauthenticated code execution. …

Vulnerability AssessmentAI
| Exploitation | Requires a registered Subscriber-level (or higher) account on a WordPress site running the wpForo Forum plugin at version 3.1.5 or earlier - achievable on any forum that permits open user registration. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a CWE-79 cross-site scripting flaw requiring an authenticated Subscriber-level account (CVSS PR:L) plus victim interaction (UI:R), yielding low-magnitude impact across the triad (C:L/I:L/A:L) with a scope change (S:C) reflecting script execution in another user's browser security context - the classic justification for the 6.5 stored/reflected XSS score Patchstack assigns. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No exact fixed version is listed in the provided intelligence; affected versions are through 3.1.5, so the primary action is to check the Patchstack advisory and wpForo vendor release notes for a patched version beyond 3.1.5 and upgrade immediately when available. … Detailed patch versions, workarounds, and compensating controls in full report. |
