Last modified

CVE-2026-64619 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. FileCodeBox before 2.4 contains a rate-limit bypass vulnerability in the IPRateLimit class that allows unauthenticated attackers to circumvent request throttling by supplying attacker-controlled X-Real-IP and X-Forwarded-For headers without verification of trusted reverse proxy origin. Attackers can supply unique spoofed IP values on each request to enumerate all possible share codes and retrieve other users' files without authentication.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
