    CVE-2026-65697 (GCVE-0-2026-65697)

    Vulnerability from nvd – Published: 2026-07-23 16:29 – Updated: 2026-07-23 18:12 X_Open Source Unsupported When Assigned

    Title
    Fathom Lite 1.3.1 Stored XSS via /collect Endpoint
    Summary
    Fathom Lite through 1.3.1 contains a stored cross-site scripting vulnerability in the analytics collection endpoint that allows unauthenticated attackers to inject a javascript: URI into the Top Pages dashboard by supplying a crafted hostname and pathname to the unauthenticated /collect endpoint. The parseHostname and parsePathname functions perform no URI scheme validation, allowing a javascript: hostname combined with a newline-prefixed pathname to be stored and later rendered as an anchor href in the authenticated dashboard without sanitization, enabling session hijacking and full account takeover when an operator clicks the poisoned entry.
