XML-RPC for PHP's `Wrapper::buildClientWrapperCode` method allows code injection via malicious `$client` argument
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.

In order for this weakness to be exploited, the following conditions have to apply, at the same time: - method `Wrapper::buildClientWrapperCode`, or any methods which depend on it, such as `Wrapper::wrapXmlrpcServer`, `Wrapper::wrapXmlrpcMethod` or `Wrapper::buildWrapMethodSource` must be in use. Note that they are _not_ used by default in either the Client or Server classes provided by the library; the developer has to specifically make use of them in his/her own code - the `$client` argument to either of those methods should have been built with malicious data, ie. data controlled by a 3rd party, passed to its constructor call This is most likely an uncommon usage scenario, and as such the chances of exploitation may be low. *NB* the graphical debugger which is shipped as part of the library is vulnerable to this, when used with the option "Generate stub for method call" selected. In that case, the debugger will _display_ but not _execute_ the malicious code, which would have to be provided via carefully crafted values for the "Address" and "Path" inputs. The attack scenario in this case is that a developer copies into his/her own source code the php snippet generated by the

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.
