A flaw was found in jmespath.php, a library for processing JSON documents in PHP applications. This vulnerability allows a remote attacker to execute arbitrary code by crafting a malicious JMESPath expression. The `JmesPath\CompilerRuntime` component fails to properly escape function names, leading to the generation and execution of attacker-controlled PHP code within the application's cache file. This could result in a complete compromise of the affected system. Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
