AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-reachable but requires a low-privilege authenticated account (PR:L) and non-trivial conditions to steer the include path (AC:H); local file inclusion can reach code execution, giving high C/I/A.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in uxper Nuss nuss allows PHP Local File Inclusion.This issue affects Nuss: from n/a through <= 1.3.6.
AnalysisAI
Local file inclusion in the uxper Nuss WordPress theme (versions up to and including 1.3.6) lets an authenticated attacker with low-privilege access coerce the theme into including arbitrary PHP-parsable files from the server via improperly controlled include/require paths (CWE-98). Successful exploitation can disclose sensitive files and, depending on what can be included, lead to code execution, with high confidentiality, integrity, and availability impact per the CVSS 7.5 rating. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to run the uxper Nuss WordPress theme at version 1.3.6 or earlier and requires the attacker to hold a valid low-privilege authenticated WordPress session (CVSS PR:L) - not an unauthenticated remote attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score is 7.5 (High) with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H: network reachable with no user interaction, but high attack complexity (AC:H) and a requirement for low-level authentication (PR:L), offset by high impact across all three security properties. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or obtains a low-privilege WordPress account on a site running Nuss <= 1.3.6, then sends a crafted authenticated request that manipulates a theme parameter feeding a PHP include/require statement, causing the theme to include an unintended local file. By pointing the inclusion at sensitive configuration or log files (or files containing attacker-controlled PHP), they read secrets or achieve code execution. … |
| Remediation | No vendor-released patch identified at time of analysis; the record states affected 'from n/a through <= 1.3.6' without naming a fixed release, so administrators should check the vendor/ThemeForest changelog and the Patchstack advisory (https://patchstack.com/database/Wordpress/Theme/nuss/vulnerability/wordpress-nuss-theme-1-3-6-local-file-inclusion-vulnerability) for a version newer than 1.3.6 and upgrade once one is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
