When a later run in that group cancels the blocked job, the run becomes terminal while still marked as needing approval. If a maintainer later approves the run, Gitea passed the already-cancelled job back through concurrency preparation, set it to waiting, and made it claimable by a matching runner, executing fork-controlled workflow code. Exploitation requires the maintainer's later approval action, Actions to be enabled, and a runner that accepts the repository's jobs." } ], "affected": [ { "vendor": "Gitea", "product": "Gitea", "packageName": "gitea.dev", "defaultStatus": "unaffected", "versions": [ { "version": "0", "status": "affected", "lessThanOrEqual": "1.27.3", "versionType": "semver" } ] } ], "references": [ { "url": "https://github.com/go-gitea/gitea/security/advisories/GHSA-93pj-3x56-5gc2", "name": "GitHub Security Advisory GHSA-93pj-3x56-5gc2", "tags": [ "vendor-advisory" ] }, { "url": "https://github.com/go-gitea/gitea/pull/39399", "name": "Fix: go-gitea/gitea pull request #39399", "tags": [ "patch" ] }, { "url": "https://blog.gitea.com/release-of-28.0.0/", "name": "Gitea 28.0.0 release announcement", "tags": [ "release-notes" ] }, { "url": "https://github.com/go-gitea/gitea/releases/tag/v28.0.0", "name": "go-gitea/gitea v28.0.0 release", "tags": [ "release-notes" ] } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-841", "description": "CWE-841: Improper Enforcement of Behavioral Workflow" } ] } ], "credits": [ { "lang": "en", "value": "https://github.com/opensec-intelligence", "type": "tool" }, { "lang": "en", "value": "https://github.com/mayank-jangid-moon", "type": "reporter" }, { "lang": "en", "value": "https://github.com/Kushalkhemka", "type": "reporter" }, { "lang": "en", "value": "https://github.com/skigeek16", "type": "reporter" }, { "lang": "en", "value": "https://github.com/nithissh7", "type": "reporter" }, { "lang": "en", "value": "https://github.com/kewmine", "type": "reporter" }, { "lang": "en", "value": "https://github.com/bircni", "type": "remediation developer" }, { "lang": "en", "value": "https://github.com/silverwind", "type": "remediation developer" } ] }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 8.8, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "timestamp": "2026-10-07T20:19:04.289390Z", "id": "CVE-2026-104626", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-10-07T20:19:46.339Z" } } ] } }
