CVE-2026-124738
Busybox: httpd password rule bypass for pre-compressed .gz files via accept-encoding: gzip
CVSS Score

EPSS Percentile
0th
A flaw was found in BusyBox. When the HTTP daemon (httpd) has pre-compressed file support enabled, authentication checks are evaluated only against the requested URL path rather than the pre-compressed file being served. A remote attacker can exploit this flaw by requesting an uncompressed file path while specifying gzip encoding, bypassing password rules configured specifically for the compressed file. This vulnerability can lead to unauthorized information disclosure of sensitive files.
