XML-RPC for PHP allows access to local files via malicious argument to the Client::send method
OSV carries this publisher advisory for phpxmlrpc/phpxmlrpc. This is an aggregated source copy; consult the original publisher and compare update dates.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

source listedECOSYSTEM: introduced 0; fixed 4.9.0
Abusing the `$method` argument of Client::send, it was possible to force the client to _access local files_ or _connect to undesired urls_ instead of the intended target server's url (the one used in the Client constructor). This weakness only affects installations where all the following conditions apply, at the same time: - the xmlrpc Client is used, ie. not xmlrpc servers - untrusted data (eg. data from remote users) is used as value for the `$method` argument of method `Client::send()`, in conjunction with conditions which trigger usage of curl as http transport (ie. either using the https, http11 or http2 protocols, or calling `Client::setUseCurl()` beforehand) - either have set the Clients `return_type` property to 'xml', or make the resulting Response's object `httpResponse` member, which is intended to be used for debugging purposes only, available to 3rd parties, eg. by displaying it to the end user or serializing it in some storage (note that the same data can also be accessed via magic property `Response::raw_data`, and in the Request's `httpResponse` member) This is most likely a very uncommon usage scenario, and as such the chances of exploitation of this issue may

What to do next
- vendor patch
The original advisory lists fixed boundaries 4.9.0 for phpxmlrpc/phpxmlrpc. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
