CVE-2026-82383: CWE-306: Missing Authentication for Critical Function in Apache Software Foundation Apache Roller
Missing Authentication for Critical Function in Apache Roller 6.1.5 allows an unauthenticated remote attacker to persistently change a site-global configuration value (the frontpage weblog selection) on any installed instance, because the setup action remains anonymously reachable after installation and persists configuration without an authorization check. No optional feature or non-default configuration is required; the result can redirect or break the site's public frontpage, with administrative recovery available. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which restricts the write to global administrators.
AI Analysis
Technical Summary
CVE-2026-82383 is a missing authentication vulnerability (CWE-306) in Apache Roller version 6.1.5. The setup action remains accessible anonymously after installation and allows an unauthenticated attacker to persistently modify a critical site-global configuration value (the frontpage weblog selection). This vulnerability does not require any optional or non-default configuration. The unauthorized change can redirect or disrupt the public frontpage of the site. The vulnerability is resolved in Apache Roller 6.1.6 and later by restricting write access to global administrators.
Potential Impact
An unauthenticated remote attacker can persistently change the frontpage weblog selection configuration on any Apache Roller 6.1.5 instance. This can lead to redirection or breaking of the site's public frontpage, impacting site integrity and availability. However, administrative recovery is possible. There is no confidentiality impact reported. The CVSS v3.1 score is 8.2 (high severity) with network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, no confidentiality impact, high integrity impact, and low availability impact.
Mitigation Recommendations
Users should upgrade to Apache Roller version 6.1.6 or later, where this vulnerability is fixed by restricting the configuration write access to global administrators. No other mitigation or temporary workaround is indicated.
