    Low [CVE-2026-59277] org.springframework.security/spring-security-core: Spring Security: Information disclosure due to incomplete internal network classification

    CVE-2026-59277Source published Source updated

    Spring Security's InetAddressMatchers utility provides matchInternal() and matchExternal() builders for constructing an InetAddressMatcher that classifies a given IP address as belonging to an internal (private) or external (public) network. In Spring Security 7.1.0, the internal address classification did not recognize the IPv4 and IPv6 any local addresses (0.0.0.0 and::) as internal. As a result, matchExternal() incorrectly classified these addresses as external, and matchInternal() failed to classify them as internal. Applications that rely on matchInternal() or matchExternal() for IP-based access control may incorrectly treat these addresses as external, potentially allowing unauthorized read access to resources intended for internal networks only.

    Mitigation guidance
    • Mitigation for this issue is either not available or does not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation use cases, and the lack of negative side effects to extended use. For the above product(s), Red Hat recommends that customers evaluate each potential workaround as part of their own risk assessment. Upstream fix: upgrade Spring Security to 7.1.1 or later. Workaround: replace InetAddressMatchers.matchInternal() or matchExternal() usage with explicit CIDR-based IpAddressMatcher rules for the private ranges your deployment requires (for example 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
