CVE-2026-71553 · ApostropheCMS: 2nd-order prototype pollution via PATCH leading to single-request persistent DoS
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
