HIGHNVD 8.68.6—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.6 under NVD CVSS v3. EPSS exploit probability: 0.7% (51st percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

changedetection.io is a free open source web page change detection, website watcher, restock monitor and notification service. Improper input validation in the application can allow attackers to perform local file read (LFR) or path traversal attacks. These vulnerabilities occur when user input is used to construct file paths without adequate sanitization or validation. For example, using file:../../../etc/passwd or file: ///etc/passwd can bypass weak validations and allow unauthorized access to sensitive files. Even though this has been addressed in previous patch, it is still insufficient. This vulnerability is fixed in 0.48.05.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
