AI-suggested

Upgrade ag-psd to version 31.0.1 or later, where this vulnerability is fixed. No other mitigation is required as the fix addresses the improper memory limit handling and unbounded decompression.

Description

CVE-2026-63501 affects the ag-psd JavaScript library used for reading and writing Photoshop Document files. Versions prior to 31.0.1 improperly handle memory limits during PSD layer decoding and ZIP decompression, allowing attackers to cause excessive memory allocation. This can lead to process memory exhaustion and denial of service. The issue is fixed in version 31.0.1.
