CVE-2023-32235
Published: 05 May 2023
Summary
CVE-2023-32235 is a high-severity Path Traversal (CWE-22) vulnerability in Ghost Ghost. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 0.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Ghost versions prior to 5.42.1 contain a directory traversal flaw in frontend/web/middleware/static-theme.js. The vulnerability allows remote attackers to supply crafted paths such as /assets/built%2F..%2F..%2F/ and retrieve arbitrary files stored inside the currently active theme directory.
Unauthenticated attackers reachable over the network can exploit the issue to read any file within the theme folder. The CVSS 7.5 rating reflects that no credentials or user interaction are required and that the primary impact is high confidentiality loss, while integrity and availability remain unaffected.
The maintainers addressed the flaw in release 5.42.1; the corrective change is shown in commit 378dd913aa8d0fd0da29b0ffced8884579598b0f. The EPSS score stands at 0.9409 with an identical recorded peak, indicating sustained but not newly emerging exploitation interest.
