Prior to 1.8089.0, Claude Desktop on Windows invokes git.exe through uv_spawn without an absolute path, allowing Windows search-path resolution to select a malicious git.exe placed in the opened project's current working directory before the intended system executable. Opening an attacker-controlled or shared repository can therefore execute the substituted program with the user's privileges. This issue is fixed in version 1.8089.0.","epss":{"date":"2026-11-09","percentile":0.21367,"score":0.00287},"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":7.5,"severity":"high","source":"NVD: security-advisories@github.com","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1794239183742,"publishedAt":1793736472495,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/anthropics/claude-code/security/advisories/GHSA-4p2j-qj3c-6x84"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/anthropics/claude-code/security/advisories/GHSA-4p2j-qj3c-6x84"},{"source":"GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/anthropics/claude-code/security/advisories/GHSA-4p2j-qj3c-6x84"}],"remediation":[{"kind":"fix","source":"GitHub GHSA-4p2j-qj3c-6x84","text":"Claude Desktop (anthropic): GitHub reports patched versions 1.8089.0.
