{"id":"GHSA-6ph4-r249-58p2","summary":"Duplicate Advisory: knowns vulnerable to command injection","details":"# Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-mc52-mwq4-vfx3. 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account without any verification.","modified":"2026-10-06T19:00:43.116804009Z","published":"2026-09-08T00:30:22Z","withdrawn":"2026-10-06T18:57:55Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-10-06T18:57:55Z","nvd_published_at":"2026-09-07T23:16:53Z","cwe_ids":["CWE-78"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/knowns-dev/knowns/security/advisories/GHSA-mc52-mwq4-vfx3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86540"},{"type":"WEB","url":"https://github.com/knowns-dev/knowns/commit/d3989829fb5095666d23d005b2f78a082832a396"},{"type":"PACKAGE","url":"https://github.com/knowns-dev/knowns"},{"type":"WEB","url":"https://github.com/knowns-dev/knowns/blob/v0.29.1/internal/lsp/detect.go#L128-L157"},{"type":"WEB","url":"https://github.com/knowns-dev/knowns/blob/v0.29.1/internal/models/config.go#L205-L216"},{"type":"WEB","url":"https://github.com/knowns-dev/knowns/releases/tag/v0.30.0"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/knowns-before-0.30.0-arbitrary-code-execution-via-lsp-binary"}],"affected":[{"package":{"name":"knowns","ecosystem":"npm","purl":"pkg:npm/knowns"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.30.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-6ph4-r249-58p2/GHSA-6ph4-r249-58p2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"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"}]}
