Denial of Service in apostrophe

  • Disclosed: 03.09.2020
  • Updated: 11.10.2026 10:22

Versions of apostrophe prior to 2.97.1 are vulnerable to Denial of Service. The apostrophe-jobs module sets a callback for incoming jobs and doesn't clear it regardless of its status. This causes the server to accumulate callbacks, allowing an attacker to start a large number of jobs and exhaust system memory.

Recommendation

Upgrade to version 2.97.1 or later.
