CVE-2026-29039 is a critical vulnerability in changedetection.io versions prior to 0.54.4, allowing attackers to read arbitrary files from the filesystem. This is due to improper validation of user-supplied XPath expressions, which can leverage the unparsed-text() function for file disclosure. With a CVSS score of 8.8 (High), this vulnerability presents a significant risk as it can be exploited remotely with low attack complexity and no user interaction. While there is no known active exploitation, publicly available exploit code, or significant community discussion, organizations using affected versions should prioritize patching to mitigate this severe risk.
