An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-46409 in the wild and no public exploit code.\n\nAffected product: openyak. 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-2026-46409/ (Markdown: https://insights.sbomify.com/CVE-2026-46409/index.md)","id":"CVE-2026-46409","markdown":"https://insights.sbomify.com/CVE-2026-46409/index.md","name":"CVE-2026-46409","record":{"aliases":["CVE-2026-51386","GHSA-ccxp-q2w5-27jw"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenYak desktop runtime","requires_auth":"none","summary":"A malicious webpage can exploit missing CSRF protections in OpenYak's local API to execute arbitrary shell commands and steal data.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-352","name":"Cross-Site Request Forgery"},{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"},{"id":"CWE-346","name":"Origin Validation Error"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"OpenYak is a local-first agent runtime for reliable tool-using models, with a desktop workspace built on top. Prior to version 1.1.3, the OpenYak desktop backend binds an HTTP API to `127.0.0.1:\u003crandom port\u003e` (commonly 19141) without server-side Origin validation, loopback authentication, or Content-Type enforcement, and with a wildcard CORS policy. Any webpage a user visits while OpenYak is running can issue cross-origin requests to this local server — the browser acts as a proxy into loopback, bypassing OS-level network isolation. Chained, this lets a malicious page execute arbitrary shell commands on the host (RCE) via the build agent with `permission_presets.bash=true`, shut down the service, and exfiltrate chat history and account PII — with no user interaction beyond opening the page. Version 1.1.3 patches the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"OpenYak local API: unauthenticated CSRF chain leads to Remote Code Execution","id":"CVE-2026-46409","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"FileBrowser Quantum: unauthenticated user share share info","id":"CVE-2026-46410"},"packages":[],"prev":{"headline":"Vvveb: checkout IDOR allows unauthorized reuse of another user's cart","id":"CVE-2026-46408"},"products":["openyak"],"published":"2026-08-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-11","vendors":["openyak"]},"summary":"A malicious webpage can exploit missing CSRF protections in OpenYak's local API to execute arbitrary shell commands and steal data.","url":"https://insights.sbomify.com/CVE-2026-46409/"}
