It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-18656 in the wild and no public exploit code.\n\nAffected product: Amazon Kiro IDE. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-18656/ (Markdown: https://insights.sbomify.com/CVE-2026-18656/index.md)","id":"CVE-2026-18656","markdown":"https://insights.sbomify.com/CVE-2026-18656/index.md","name":"CVE-2026-18656","record":{"aliases":["GHSA-hhmj-6g9r-9vvq"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kiro IDE","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Windows users by tricking them into opening a malicious project directory in Kiro IDE.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[{"product":"kiro_ide","vendor":"amazon"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"An uncontrolled search path element in Kiro IDE before version 1.0.228 on Windows might allow a remote unauthenticated actor to execute arbitrary code via a maliciously crafted project directory containing an executable that bypasses workspace trust protections when a local user opens the directory.\n\nTo remediate this issue, users should upgrade to version 1.0.228 or higher.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Executable Resolution from Untrusted Project Directory in Kiro IDE on Windows","id":"CVE-2026-18656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Executable Resolution from Untrusted Project Directory in Kiro CLI on Windows","id":"CVE-2026-18657"},"packages":[],"prev":{"headline":"Broker Credential and OAuth Token Disclosure in AWS Labs Amazon MQ MCP Server via Prompt Injection","id":"CVE-2026-18655"},"products":["Kiro IDE"],"published":"2026-08-04","related":[{"cvss_score":8.6,"headline":"Kiro IDE Insufficient File Write Restrictions to Execution-Sensitive Paths","id":"CVE-2026-10591","kev_date_added":null,"published":"2026-06-02"},{"cvss_score":8.4,"headline":"Command Injection in Kiro GitLab Merge Request Helper","id":"CVE-2026-0830","kev_date_added":null,"published":"2026-01-09"},{"cvss_score":6.7,"headline":"Kiro IDE Sensitive Workspace Data Exfiltration via Agent-Written Workspace Configuration","id":"CVE-2026-89332","kev_date_added":null,"published":"2026-09-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Amazon"]},"summary":"Remote attackers can execute arbitrary code on Windows users by tricking them into opening a malicious project directory in Kiro IDE.","url":"https://insights.sbomify.com/CVE-2026-18656/"}
