An attacker who can construct a case variant of another user's registered RSA public key for which they can derive the private key could have that key matched to the victim's account and authenticate over SSH as that user. Keys are now looked up by fingerprint.","state":0,"publishedAt":"2026-10-06T19:22:57.192+00:00","modifiedAt":"2026-10-07T14:17:20.596+00:00","affected":[{"ecosystem":"Vendor product","name":"gitea.dev","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Gitea\",\n                    \"product\": \"Gitea\",\n                    \"packageName\": \"gitea.dev\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.27.3\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/go-gitea/gitea/security/advisories/GHSA-8pwg-hcgm-54cp","https://github.com/go-gitea/gitea/pull/39423","https://blog.gitea.com/release-of-28.0.0/","https://github.com/go-gitea/gitea/releases/tag/v28.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103059","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103059","identifiers":["CVE-2026-103059"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
