Prior to 0.3.1, DerReader.readLength() accepts excessive long-form DER length octets, accumulates them into an Int, and primitive readers allocate arrays without checking the declared size against the remaining input. An application or user that loads an attacker-provided private-key file through SshClient.authenticatePublicKey(), SshKeys.decodePemPrivateKey(), SshSigning.sign(), or SshSigning.getPublicKey() can trigger integer wraparound, excessive allocation, or an uncaught OutOfMemoryError. SSH server host keys and agent-forwarding messages do not use this application-supplied private-key input path. No usable weakened key and no confidentiality or integrity impact have been demonstrated. This issue is fixed in version 0.3.1.","state":0,"publishedAt":"2026-10-13T15:54:48.714+00:00","modifiedAt":"2026-10-13T16:07:53.782+00:00","affected":[{"ecosystem":"Vendor product","name":"cbssh","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"connectbot\",\n                    \"product\": \"cbssh\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.3.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.7,"severity":"MEDIUM"}],"references":["https://github.com/connectbot/cbssh/security/advisories/GHSA-vc8p-8pxg-rfwg","https://github.com/connectbot/cbssh/commit/2bb917517bec0df229a02ca768d6eae84be72df0","https://github.com/connectbot/cbssh/releases/tag/v0.3.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54697","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54697","identifiers":["CVE-2026-54697"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
