So, has this issue been addressed?
The unpatched vulnerability in Linux Pling is affecting Pling-based free and open-source software (FOSS) marketplaces for the Linux platform and has the potential to be abused in order to stage supply-chain attacks and achieve remote code execution (RCE).
Linux marketplaces that are based on the Pling platform are vulnerable to a wormable [cross-site scripting] with the potential for a supply-chain attack. The native PlingStore application is affected by an RCE vulnerability, which can be triggered from any website while the app is running.
As the application can install other applications, it has another built-in mechanism to execute code on the [operating system] level. As it turns out, that mechanism can be exploited by any website to run arbitrary native code while the PlingStore app is open in the background.
