Last modified

CVE-2026-35000 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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.. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
