CVE-2026-35000: Webtechnologies Changedetection

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Webtechnologies Changedetection: before 0.54.7 (fixed in 0.54.7)
