Not reviewed by a person. > Magick.NET packages (Q8-x64, Q16 AnyCPU, Q16-HDRI, and OpenMP variants for x64, x86, and arm64) before 14.10.3 are vulnerable. A user opening a crafted PSB (PSD v2) file in a 32-bit build can trigger an integer overflow that causes a heap out-of-bounds read, leading to information disclosure or a crash. Upgrade to version 14.10.3 or later. Written 9 Nov 2026. ## Not analysed yet We haven’t published our analysis of this Advisory yet. Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation - 6.3 Medium, CVSS 4.0: `CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N`, from CNA (VulnCheck) - **CISA KEV:** Not listed. - **EPSS:** 0.0024, the 14th percentile, on 10 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 25 Feb 2026, 15:20 UTC: [Confirmed by GitHub Advisory Database](https://github.com/advisories/GHSA-273h-m46v-96q4) - 21 Jun 2026, 13:26 UTC: [Confirmed by the CVE List](https://www.cve.org/CVERecord?id=CVE-2026-56367) - 31 Oct 2026, 15:22 UTC: First seen by agentprime - 31 Oct 2026, 15:22 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-273h-m46v-96q4) ## Sources - [GitHub Advisory Database: GHSA-273h-m46v-96q4](https://github.com/advisories/GHSA-273h-m46v-96q4) - [OSV: GHSA-273h-m46v-96q4](https://osv.dev/vulnerability/GHSA-273h-m46v-96q4) - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
