Typecho · Typecho · CVE-2026-7025
**Name of the Vulnerable Software and Affected Versions**
Typecho versions prior to 1.3.1
**Description**
An issue exists in the Ping Back Service Endpoint within the `Service::sendPingHandle()` function of the `var/Widget/Service.php` file. Remote attackers can trigger server-side request forgery (SSRF)—a flaw where the server is coerced into making unintended requests—by manipulating the `X-Pingback/link` argument.
**Recommendations**
Update to a version later than 1.3.0.
As a temporary workaround, restrict access to the Ping Back Service Endpoint or the `Service::sendPingHandle()` function to minimize the risk of exploitation.
