CVE-2022-26960 is a critical-severity Path Traversal (CWE-22) vulnerability in Std42 Elfinder. Its CVSS base score is 9.1 (Critical).
Operationally, ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.
CVE-2022-26960 is a path traversal vulnerability in connector.minimal.php within std42 elFinder versions through 2.1.60. The flaw stems from improper handling of absolute file paths and is tracked under CWE-22, carrying a CVSS 3.1 score of 9.1.
Unauthenticated remote attackers can exploit the issue over the network to read, write, and browse arbitrary files outside the application's configured document root, achieving high impact on confidentiality and integrity without any user interaction or privileges.
Public references point to a fix committed to the elFinder repository that addresses the path traversal logic, and detailed analysis from Synacktiv describes the vulnerability and its exploitation implications. The associated EPSS score remains elevated near 0.84 with no material post-disclosure climb indicated.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of file-path inputs to reject absolute paths and directory-traversal sequences that enable the elFinder bypass.
Enforces the intended access-control policy that only files inside the configured document root may be read or written, blocking the unauthorized operations.
Implements information-flow rules that confine file-system operations to the designated root, limiting the scope of any path-traversal attempt.
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.
