Contributor access is PR:L not PR:H; once authenticated, path traversal to LFI is straightforward with no special conditions, so AC:L.

The Eventin WordPress plugin before 4.1.21 does not properly validate a template path value before using it to include a local file, allowing users with contributor-level access and above to include and execute arbitrary local PHP files.
AnalysisAI
Local file inclusion in Eventin WordPress plugin before 4.1.21 enables authenticated contributors and higher-privileged users to include and execute arbitrary PHP files on the web server. The plugin fails to validate a user-supplied template path parameter before passing it to a PHP file-inclusion routine, allowing path traversal to any locally accessible PHP file. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress account at contributor level or higher (Contributor, Author, Editor, or Administrator). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The published CVSS vector (PR:H/AC:H) appears to understate accessibility: the description explicitly states contributor-level access suffices, which is PR:L in CVSS terms, and exploitation of a path-traversal-to-LFI flaw typically requires only a valid path string - no complex preconditions beyond possessing that account. … 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 | Update Eventin to version 4.1.21 or later, which is the vendor-released patch for this issue; this is the primary and recommended fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
