In versions prior to 1.11.5, authenticated clients can bypass --authfile ACL restrictions and tunnel traffic to arbitrary destinations reachable from the server. The ACL is enforced only during the initial handshake against declared remotes, but never on subsequent SSH channels that carry actual traffic. A malicious client can authenticate with a permitted remote, then open channels to any host:port it wants. This issue has been fixed in version 1.11.5.","state":0,"publishedAt":"2026-08-03T21:16:39.597+00:00","modifiedAt":"2026-10-23T21:10:00.157+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:H/SA:L/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":8.5,"severity":"HIGH"}],"references":["https://github.com/jpillora/chisel/commit/44310b65667a97901874ffdf4815b3732c22eaa3","https://github.com/jpillora/chisel/security/advisories/GHSA-24fp-5v3p-rvpw"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-48113","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-08-03T21:16:39.597","lastModified":"2026-10-23T21:10:00.157"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
