## Technical details

The vulnerability stems from multiple flawed dependencies: jsdiff before 5.2.2 with an infinite loop in parsePatch() consuming unbounded memory when processing patch headers with certain line-break characters, and improper input validation in Maximo AI Service itself. An unauthenticated remote attacker can send a malicious patch or specially crafted input to trigger the DoS, requiring no user interaction or authentication. The fix requires upgrading the affected third-party libraries.
