This link is maintained to preserve external references.\n\n# Original Description\n\nknowns versions before 0.30.0 fail to validate the settings.lsp.languages binary field in project configuration files, allowing attackers to execute arbitrary binaries by crafting a malicious .knowns/config.json file. When a repository with a crafted configuration is opened, the unvalidated binary path is executed twice under the user's account without any verification.","state":2,"publishedAt":"2026-09-08T00:30:22+00:00","modifiedAt":"2026-10-06T19:00:43.116804+00:00","affected":[{"ecosystem":"npm","name":"knowns","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.30.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":null,"severity":null},{"system":"CVSS_V4","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/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","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/knowns-dev/knowns/security/advisories/GHSA-mc52-mwq4-vfx3","https://nvd.nist.gov/vuln/detail/CVE-2026-86540","https://github.com/knowns-dev/knowns/commit/d3989829fb5095666d23d005b2f78a082832a396","https://github.com/knowns-dev/knowns","https://github.com/knowns-dev/knowns/blob/v0.29.1/internal/lsp/detect.go#L128-L157","https://github.com/knowns-dev/knowns/blob/v0.29.1/internal/models/config.go#L205-L216","https://github.com/knowns-dev/knowns/releases/tag/v0.30.0","https://www.vulncheck.com/advisories/knowns-before-0.30.0-arbitrary-code-execution-via-lsp-binary"],"sourceUrl":"https://github.com/advisories/GHSA-6ph4-r249-58p2","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-6ph4-r249-58p2","identifiers":["GHSA-6ph4-r249-58p2"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
