CVE-2026-97730
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/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-2026-97730 is a high-severity Path Traversal: '../filedir' (CWE-24) vulnerability in Netgate (inferred from references). Its CVSS base score is 8.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked in the top 38% 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.

Vulnerability Data
In Netgate pfSense Plus before 26.07 and pfSense CE before 2.9.0, a Local File Inclusion (LFI) vulnerability in the Dashboard (index.php) widget sequence data handling allows an authenticated attacker to execute arbitrary PHP code. To exploit this, an attacker with…

privileges to modify Dashboard settings and write arbitrary files to the pfSense firewall system (e.g., /tmp/test.widget.php) can submit a crafted widget sequence value containing a path traversal payload (e.g., ../../../../../../../../../../../tmp/test). The Dashboard will subsequently read and execute the arbitrary PHP file as if it were a standard widget.

Enforced access authorizations can limit the damage even when path traversal succeeds.
Input validation directly neutralizes '../' sequences in externally-supplied pathnames before they are resolved.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require input validation and path sanitization that prevent ../ traversal.

Secure SDLC mandates input validation and path canonicalization that directly block ../ traversal.
Application security requirements explicitly call for controls against path traversal in file-handling functions.
Secure architecture principles reduce attack surface but do not prescribe the specific coding fix.
Secure coding standards require neutralizing ../ sequences and canonicalizing paths before file operations.
Security testing in development catches path-traversal flaws before release.
