CVE-2026-7025 Details
Description
A vulnerability was found in Typecho up to 1.3.0. This vulnerability affects the function Service::sendPingHandle of the file var/Widget/Service.php of the component Ping Back Service Endpoint. The manipulation of the argument X-Pingback/link results in server-side request forgery. The attack may be launched remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
A server-side request forgery (SSRF) vulnerability exists in Typecho versions through 1.3.0. The issue is located in the Ping Back Service Endpoint, specifically within the `Service::sendPingHandle` function of the `var/Widget/Service.php` file. This vulnerability allows remote attackers to manipulate the `X-Pingback/link` header, leading to unauthorized requests being sent from the server to internal or external targets. The vulnerability arises from weak validation of time-based tokens, which can be bypassed, enabling exploitation of the Pingback relay feature to access internal services or networks.
Typecho users are advised to disable the Pingback service if not needed, apply strict IP filtering to reject URLs pointing to private or reserved IP ranges, and patch the token validation to ensure proper validation before processing requests.
