ApostropheCMS versions 4.32.0 and earlier are vulnerable to a denial of service attack due to improper handling of the inherited path in the PATCH /api/v1/article/:id endpoint. An authenticated editor can exploit this vulnerability to overwrite the shared Object.prototype.toString function's call property, leading to a persistent disruption of service until the application is restarted. Organizations using this content management system should prioritize patching to mitigate the risk of service outages.

Original NVD Description

ApostropheCMS is an open-source Node.js content management system. In 4.32.0 and earlier, PATCH /api/v1/article/:id accepts the inherited path toString.call and passes it through the utility module to apos.util.set() and apos.util.get(), allowing an authenticated editor to overwrite the shared Object.prototype.toString function's call property and cause a persistent process-wide denial of service until restart.
