Summary

CVE-2022-26960 is a critical-severity Path Traversal (CWE-22) vulnerability in Std42 Elfinder. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); 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.

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.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

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.

PR.PS-02 partial match
prevents

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 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
