Lifecycle Timeline
4Description
ChangeDetection.io versions prior to 0.54.7 contain a protection bypass vulnerability in the SafeXPath3Parser implementation that allows attackers to read arbitrary local files by using unblocked XPath 3.0/3.1 functions such as json-doc() and similar file-access primitives. Attackers can exploit the incomplete blocklist of dangerous XPath functions to access sensitive data from the local filesystem.
Analysis
Local filesystem disclosure in ChangeDetection.io <0.54.7 allows authenticated remote attackers to read arbitrary files via incomplete XPath 3.0/3.1 function blocklist bypass. The SafeXPath3Parser implementation fails to block dangerous file-access functions like json-doc(), enabling sensitive data exfiltration. …
