ag-psd is a JavaScript library for reading and writing Photoshop Document files. Before the allocation-limit remediation attempt in version 31.0.0, readPsd() commits image and layer buffers from attacker-declared PSD geometry before validating the declarations against the actual available data or sane allocation limits. The psdReader.js implementation sizes off-heap typed arrays using width, height, channels, depth and per-layer rectangles, so a tiny PSD declaring enormous geometry can force multi-gigabyte memory allocation before a later bounds error. The reported 52-byte input on Node 24 produced approximately 3.17 GB peak RSS before a RangeError; under memory pressure the process can be terminated before the error can be caught, and concurrent inputs can exhaust memory. Services reading untrusted PSDs are exposed to denial of service. This differs from genuinely large PSD files whose memory demand is proportional to real input content. Version 31.0.0 adds a composite-image allocation limit, but complete coverage of the separately described layer-rectangle allocation path is not established and requires curator residual/scope review.
CVE-2026-62297
“—” beside the score: it is equal to the CVSS score beside it.
This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3% (27th percentile of EPSS-scored CVEs). No GitHub Security Advisory CVSS is on record for this CVE.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

No released fix is confirmed on this page, but CISA's timeline does not wait for a fix's release: it starts when an agency identifies the flaw on an asset and updates the CDM Agency and Federal Dashboard, and the directive counts patching, decommissioning the system or another action as remediation.

Data Freshness Timeline
(refreshed 7× in last 7d / 15× in last 30d)
Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed its CVE.org record (CNA or CISA ADP). An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). "EchelonGraph re-scored" is our own recompute of this CVE's score, not an update from a source, and is not counted in the refreshes above. Most recent first.
