CVE-2025-49874 is a Missing Authorization vulnerability (CWE-862) identified in the Arconix FAQ plugin developed by tychesoftwares, affecting versions up to 1.9.6. This vulnerability arises from improperly configured access control mechanisms within the plugin, allowing users with limited privileges (requiring at least low-level privileges but no user interaction) to access or perform actions that should be restricted. The vulnerability is network exploitable (AV:N) with low attack complexity (AC:L), requiring some level of privileges (PR:L) but no user interaction (UI:N). The impact primarily affects confidentiality, allowing unauthorized information disclosure, but does not affect integrity or availability. The vulnerability is unscoped (S:U), meaning the impact is confined to the vulnerable component without affecting other system components. No known exploits are currently reported in the wild, and no patches have been linked yet. The CVSS score of 4.3 reflects a medium severity level, indicating a moderate risk that should be addressed promptly to prevent potential unauthorized data access within affected environments. The root cause is the failure to enforce proper authorization checks on certain functionalities of the Arconix FAQ plugin, which could allow attackers with limited access to bypass intended restrictions.

For European organizations, the impact of CVE-2025-49874 depends largely on the deployment of the Arconix FAQ plugin within their web infrastructure. Organizations using WordPress or similar CMS platforms with this plugin may face unauthorized disclosure of FAQ content or related sensitive information if the plugin is used to manage internal or customer-facing knowledge bases. While the vulnerability does not allow modification or disruption of services, unauthorized access to information could lead to leakage of business-sensitive data or internal procedures, potentially aiding further attacks or social engineering. Sectors such as government, healthcare, finance, and critical infrastructure operators that rely on web-based FAQ systems for internal or external communication could be more exposed. The medium severity suggests that while the threat is not immediately critical, it could be leveraged as part of a broader attack chain, especially in environments where privilege escalation is possible or where the plugin is integrated with other sensitive systems.

1. Immediate review and audit of all Arconix FAQ plugin installations across organizational web assets to identify affected versions. 2. Restrict access to the plugin’s administrative and user interfaces to only trusted roles with necessary privileges, minimizing the number of users with low-level privileges that could exploit this vulnerability. 3. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the Arconix FAQ plugin endpoints. 4. Monitor logs for unusual access patterns or privilege misuse related to the plugin. 5. Engage with the vendor (tychesoftwares) for official patches or updates and apply them promptly once available. 6. Where possible, replace or supplement the Arconix FAQ plugin with alternative solutions that enforce stricter access controls. 7. Conduct regular security training for administrators to recognize and remediate access control misconfigurations. 8. Employ principle of least privilege for all CMS users and review user roles periodically to ensure minimal necessary access.
