Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progress runs that share a concurrency group with `cancel-in-progress` enabled, without approval and without running any code. On self-hosted runners this can interrupt deployments and leave partial state behind.","state":0,"publishedAt":"2026-10-06T19:23:40.05+00:00","modifiedAt":"2026-10-07T15:58:09.298+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-4j4g-m7mr-hp5j","https://github.com/go-gitea/gitea/pull/39399","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-2026-103670","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103670","identifiers":["CVE-2026-103670"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
