When parsing Adobe Photoshop Document (PSD) files, the readPsd() function reads image dimensions and color depth directly from the file header and allocates off-heap typed arrays without validating whether the requested memory size is proportional to the input stream or bounded by operational thresholds. An unauthenticated attacker can supply a crafted 52-byte PSD payload that triggers an immediate 3.35 GB memory allocation, resulting in process termination via the operating system Out-Of-Memory (OOM) killer.\n\n## TL;DR\nVersions of the JavaScript PSD parser library ag-psd prior to 31.0.0 allocate image buffers based directly on unvalidated width, height, and bit-depth fields in the PSD header. A crafted 52-byte payload can force the Node.js runtime to allocate over 3.35 GB of off-heap memory, causing immediate denial of service via Out-Of-Memory (OOM) crashes.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CVE ID**: CVE-2026-62297 (GHSA-qfx6-q44v-9qqw)\n- **Weakness Class**: CWE-789: Memory Allocation with Excessive Size Value\n- **CVSS v3.1 Score**: 7.5 HIGH (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)\n- **EPSS Score**: 0.34% (27.71st Percentile)\n- **Affected Component**: ag-psd (< 31.0.0) readPsd() / createImageDataBitDepth()\n- **Impact**: Denial of Service via 3.35+ GB Off-Heap OOM Exhaustion\n- **Exploit Status**: Public PoC Available (52-byte PSD payload)\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- ag-psd (npm package)\n- **ag-psd**: < 31.0.0 (Fixed in: `31.0.0`)\n\n## Mitigation\n\n- Enforce strict memory allocation ceilings via the totalMemoryLimit reader option.\n- Defer bitmap allocation and decompression during initial parsing using useRawData: true and useRawThumbnail: true.\n- Validate composite document dimensions, bit depth, layer count, and individual layer bounding rectangles before decoding pixel data.\n- Isolate PSD parsing workloads in dedicated worker processes or ephemeral containers with strict OS-level cgroup limits.\n\n**Remediation Steps:**\n1. Upgrade the ag-psd dependency to version 31.0.0 or later via npm install ag-psd@^31.0.0.\n2. Pass an explicit totalMemoryLimit option (e.g., 50 MB to 100 MB) to all readPsd() calls handling untrusted input instead of relying on the 2 GB default.\n3. Enable useRawData: true in readPsd() options to inspect psd.width, psd.height, and layer coordinates prior to invoking getCompositeImageData() or getLayerImageData().\n\n## References\n\n- [GitHub Security Advisory (GHSA-qfx6-q44v-9qqw)](https://github.com/Agamnentzar/ag-psd/security/advisories/GHSA-qfx6-q44v-9qqw)\n- [Official Fix Commit (v31.0.0)](https://github.com/Agamnentzar/ag-psd/commit/2d7da68400990bae8ba248a065eb45021fa8000a)\n- [ag-psd Release 31.0.0 Tree](https://github.com/Agamnentzar/ag-psd/tree/31.0.0)\n- [Official CVE Record (CVE.org)](https://www.cve.org/CVERecord?id=CVE-2026-62297)\n- [National Vulnerability Database (NVD) -
