Attack Chain

1. Attacker identifies a target WordPress site running a vulnerable version of the VikRentCar plugin (<= 1.4.8).
2. Attacker crafts a malicious HTTP request targeting a sensitive function within the VikRentCar plugin endpoint that lacks CSRF protection (e.g., token validation).
3. Attacker embeds the malicious request into a deceptive link or an iframe on an external website controlled by the attacker.
4. An authenticated administrator with an active session in the WordPress dashboard visits the attacker-controlled website.
5. The administrator's browser automatically includes active session cookies and makes the request to the target WordPress site.
6. The VikRentCar plugin, failing to verify the request origin or session token, processes the administrative action as if requested by the authorized user.
7. The target WordPress site completes the unauthorized configuration or administrative modification.

Impact

Successful exploitation allows attackers to perform administrative operations on behalf of an authenticated victim, leading to configuration changes, potential site takeover, or the creation of backdoors. Given the CVSS v3.1 score of 8.8, this vulnerability poses a critical impact to the availability and integrity of the affected WordPress application.

Recommendation

• Update the VikRentCar plugin to the version subsequent to 1.4.8 once the vendor releases a patch addressing CVE-2026-112836.
• Audit access logs for suspicious administrative actions originating from unusual referrers or unexpected user-agent combinations.
• Implement strict Content Security Policy (CSP) headers to mitigate potential CSRF and related injection vectors.
• Ensure that the WordPress dashboard and plugin management interface are accessible only through restricted IP ranges or behind a VPN where feasible.
