CVE-2025-67926 identifies a missing authorization vulnerability in the Shahjahan Jewel Fluent Support plugin, a tool commonly used for customer support ticket management within WordPress environments. The vulnerability arises from incorrectly configured access control security levels, which fail to properly enforce authorization checks on certain functions or endpoints. This misconfiguration allows attackers to perform unauthorized actions that should normally be restricted, such as viewing, modifying, or deleting support tickets or related data. The affected versions include all releases up to and including 1.10.4. Although no public exploits have been reported, the flaw's presence in a widely used plugin increases the risk of exploitation once attackers develop proof-of-concept code. The lack of a CVSS score indicates the vulnerability is newly disclosed and pending detailed assessment. However, missing authorization vulnerabilities typically have a high impact because they compromise the fundamental security principle of access control, potentially exposing sensitive customer data or enabling privilege escalation within the support system. The vulnerability was reserved in December 2025 and published in January 2026, indicating recent discovery and disclosure. No patches or mitigations have been officially released yet, emphasizing the need for immediate attention from users of the plugin.

For European organizations, the impact of this vulnerability could be significant, especially for those relying on Fluent Support for managing customer interactions and support tickets. Unauthorized access could lead to exposure of sensitive customer information, including personal data protected under GDPR, resulting in compliance violations and potential fines. Integrity of support data could be compromised, leading to misinformation, disruption of support workflows, and erosion of customer trust. Availability might also be affected if attackers manipulate or delete support tickets, causing operational disruptions. The risk is heightened for organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government services. Additionally, unauthorized access could be leveraged as a foothold for further lateral movement within the network, increasing the overall security risk. The absence of known exploits currently provides a window for proactive mitigation, but the vulnerability’s nature demands urgent remediation to prevent future attacks.

Organizations should immediately inventory their use of the Shahjahan Jewel Fluent Support plugin and verify the version in use. Until an official patch is released, administrators should restrict access to the plugin’s administrative and support interfaces to trusted personnel only, employing network-level controls such as IP whitelisting or VPN access. Conduct a thorough review and hardening of access control configurations within the plugin settings to ensure minimal privilege principles are enforced. Monitor logs for unusual access patterns or unauthorized attempts to interact with support tickets. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting Fluent Support endpoints. Prepare for rapid deployment of patches once available by establishing a testing and deployment workflow. Additionally, consider isolating the support system from critical infrastructure to limit potential lateral movement. Educate support staff about the vulnerability and encourage vigilance for phishing or social engineering attempts that might exploit this weakness.
