CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-4828 is a critical-severity Path Traversal (CWE-22) vulnerability in Schiocco Support Board. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique /etc/passwd and /etc/shadow (T1003.008); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The Support Board plugin for WordPress is vulnerable to arbitrary file deletion in the sb_file_delete function due to insufficient file path validation. This affects all versions through 3.8.0 and is tracked as CWE-22. Successful exploitation can delete any file on the server, including wp-config.php, which commonly leads to remote code execution.
An unauthenticated attacker can chain this flaw with CVE-2025-4855 to trigger the deletion without authentication. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting network-accessible attack with high impact on confidentiality, integrity, and availability.
The EPSS score remains flat at 0.0861 with no material increase after disclosure. Public references point to the plugin vendor page on CodeCanyon and a detailed Wordfence threat intelligence entry for further analysis.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes special path elements before pathname construction occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

Security testing in development catches path traversal via static/dynamic analysis.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
