CVE-2026-24578 is a vulnerability identified in the Jahid Hasan Admin login URL Change plugin, versions up to and including 1.1.5. The core issue is a missing authorization control on the functionality that allows changing the admin login URL. This means that users with limited privileges (PR:L - privileges required) can access or manipulate the admin login URL change feature without proper authorization checks. The vulnerability is remotely exploitable over the network (AV:N) with low attack complexity (AC:L) and does not require user interaction (UI:N). The scope is unchanged (S:U), and the impact is limited to confidentiality (C:L), with no impact on integrity (I:N) or availability (A:N). This could allow an attacker to gain information about the admin login URL or potentially facilitate further attacks by bypassing intended access controls. Although no exploits are currently known in the wild, the vulnerability represents a risk for environments relying on this plugin for obscuring or protecting admin login endpoints. The lack of patches or mitigation links indicates that users should be vigilant and apply updates as soon as they become available. The vulnerability is categorized as medium severity with a CVSS 3.1 score of 4.3, reflecting moderate risk primarily due to limited impact and the requirement for some privileges to exploit.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive information related to admin login URLs, which may facilitate targeted attacks such as brute force or credential stuffing by revealing or enabling access to admin endpoints. While the direct impact on system integrity and availability is minimal, the confidentiality breach can weaken overall security posture and increase the risk of subsequent attacks. Organizations that rely on this plugin to obscure or protect their admin login pages may find their defenses bypassed, potentially exposing administrative interfaces to attackers. This is particularly concerning for organizations with web-facing WordPress environments that use this plugin for security through obscurity. The medium severity rating suggests that while immediate damage may be limited, the vulnerability should not be ignored, especially in sectors with sensitive data or regulatory requirements such as finance, healthcare, and government agencies within Europe.

1. Monitor the Jahid Hasan plugin repository and official channels for patches or updates addressing CVE-2026-24578 and apply them promptly. 2. Restrict access to the admin login URL change functionality by limiting it to highly trusted administrative users only, using role-based access controls. 3. Implement network-level restrictions such as IP whitelisting or VPN access for administrative interfaces to reduce exposure. 4. Enable detailed logging and monitoring of access to admin login URL change endpoints to detect unauthorized attempts. 5. Consider disabling or replacing the plugin if immediate patching is not possible, especially in high-risk environments. 6. Conduct regular security audits and penetration tests focusing on access control mechanisms around administrative functions. 7. Educate administrators about the risks of exposing admin login URLs and encourage the use of multi-factor authentication to mitigate potential credential compromise.
