Detailsinfo

A vulnerability classified as problematic has been found in MISP sachertortephp (affected version unknown). Affected is the function Xml::build of the file lib/Cake/Utility/Xml.php of the component XML Fetching. The manipulation of the argument input with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality. CVE summarizes:

In the MISP sachertortephp library, the Xml::build() static method in lib/Cake/Utility/Xml.php contains a logic error in the conditional that gates network-based XML fetching. The original condition was written as: $options['readFile'] && strpos($input, 'http://') === 0 || strpos($input, 'https://') === 0. Because PHP's && operator has higher precedence than ||, the expression is evaluated as ($options['readFile'] && strpos($input, 'http://') === 0) || strpos($input, 'https://') === 0. As a result, when a caller explicitly sets the readFile option to false to disable file and URL reading, an input string beginning with https:// still satisfies the condition and triggers a network fetch via HttpSocket (configured to follow up to 10 redirects). The http:// branch is correctly gated by the readFile flag, but the https:// branch is not. An attacker who can influence the $input parameter passed to Xml::build() can therefore force the application to issue an outbound HTTPS request to an attacker-controlled or internal URL, even though the caller intended to suppress all remote reads. The fetched response is parsed as XML and may be returned to the caller, enabling information disclosure from internal services or external targets. This constitutes a Server-Side Request Forgery (SSRF) weakness with an information-disclosure impact. The vulnerability requires that the code path in Xml::build() be reachable with attacker-controlled input and that the readFile option be set to false (or the caller expects it to be false).

The advisory is available at github.com. This vulnerability is traded as CVE-2026-92932 since 09/17/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit.
