A flaw was found in Munin. A path traversal vulnerability in the munin-httpd static file handler allows an unauthenticated remote attacker to access arbitrary files outside the intended directory. By sending a specially crafted HTTP request that bypasses path validation checks, an attacker can read sensitive configuration files and disclose monitored service credentials.

Description OSIDB Bzimport 2026-11-10 19:29:59 UTC 
Munin munin-httpd 2.99.1 through 2.999.18 contains a path traversal vulnerability in the static file handler of Munin::Master::HTML::handle_request that allows unauthenticated attackers to read files outside the static directory. Attackers can request /static/../<file> to bypass the '/../' substring check and read munin.conf and plugin-conf.d files containing monitored service credentials.
