{"id":"CVE-2026-26514","details":"An Argument Injection vulnerability exists in bird-lg-go before commit 6187a4e. The traceroute module uses shlex.Split to parse user input without validation, allowing remote attackers to inject arbitrary flags (e.g., -w, -q) via the q parameter. This can be exploited to cause a Denial of Service (DoS) by exhausting system resources.","modified":"2026-07-08T07:59:58.071586507Z","published":"2026-03-04T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26514.json","cna_assigner":"mitre"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26514.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26514"},{"type":"REPORT","url":"https://github.com/xddxdd/bird-lg-go/issues/136"},{"type":"FIX","url":"https://github.com/xddxdd/bird-lg-go/commit/6187a4e3afce6d8c29568f8c72ca497d1f5a2b56"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/xddxdd/bird-lg-go","events":[{"introduced":"0"},{"fixed":"fc2438bbb39e0fc7b69e33ea6e0c43cba80e373f"},{"fixed":"6187a4e3afce6d8c29568f8c72ca497d1f5a2b56"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.4.1"}],"cpe":"cpe:2.3:a:xddxdd:bird-lg-go:*:*:*:*:*:go:*:*"}}],"versions":["v1.4.0","v1.3.12.1","v1.3.12","v1.3.11","v1.3.10","v1.3.9","v1.3.8","v1.3.7.1","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2.2","v1.3.2.1","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.1","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-26514.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
