    CVE-2026-63770 (GCVE-0-2026-63770)

    Vulnerability from nvd – Published: 2026-07-20 19:02 – Updated: 2026-07-28 01:05 X_Open Source
    VLAI
    Title
    Glance 0.8.5 IP Spoofing Authentication Brute-Force Protection Bypass
    Summary
    Glance through 0.8.5 contains an IP address spoofing vulnerability in the authentication handler that allows unauthenticated attackers to bypass brute-force lockout protections by supplying arbitrary values in the X-Forwarded-For request header when the server proxied option is enabled. Attackers can manipulate the leftmost value of the X-Forwarded-For header to make each login attempt appear to originate from a distinct IP address, preventing the per-IP failed-login counter from reaching the lockout threshold and enabling unlimited credential guessing against the authentication endpoint.
