Path Traversal in Craftycontrol Crafty Controller 4.5.0 – 4.8.0
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:NSummary
CVE-2026-0805 is a high-severity Path Traversal (CWE-22) vulnerability in Craftycontrol Crafty Controller. Its CVSS base score is 8.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 46th percentile by exploit likelihood (below the median); 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-0805 is an input neutralization vulnerability, classified under CWE-22 (path traversal), affecting the Backup Configuration component of Crafty Controller. This flaw enables improper handling of user-supplied input, allowing attackers to traverse directories and manipulate files outside intended paths. The vulnerability was published on 2026-01-30 and carries a CVSS v3.1 base score of 8.2 (AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N), indicating high confidentiality and integrity impacts with no availability disruption.
A remote, authenticated attacker with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) by crafting malicious inputs during backup configuration operations. Successful exploitation leads to file tampering and remote code execution (RCE), potentially allowing the attacker to alter critical files or execute arbitrary commands within the application's scope (S:C), though it requires high attack complexity (AC:H).
The primary advisory reference is a GitLab issue at https://gitlab.com/crafty-controller/crafty-4/-/issues/650, which documents the vulnerability in Crafty Controller's repository and likely includes details on patches or workarounds for mitigation.

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.
Mitigating Controls (NIST CSF 2.0) AI
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.
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.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
