An unauthenticated attacker who knows a private attachment's UUID can request it through a public repository's attachment path and retrieve its contents. This can expose issue and pull request attachments or release assets; the random attachment UUID must already be known to the attacker.","state":0,"publishedAt":"2026-10-14T14:38:17.247+00:00","modifiedAt":"2026-10-18T13:35:37.544+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\": \"1.26.0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.27.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/go-gitea/gitea/security/advisories/GHSA-frpv-2xgv-wxpq","https://blog.gitea.com/release-of-1.27.3/","https://github.com/go-gitea/gitea/pull/39048","https://github.com/go-gitea/gitea/pull/39077","https://github.com/go-gitea/gitea/releases/tag/v1.27.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-78433","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-78433","identifiers":["CVE-2026-78433"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
