Holding only such a token with `write:organization` that belongs to an owner of a public organization, an attacker could register an organization-level runner and receive jobs of the organization's private repositories that have Actions enabled, including the workflow content, Actions secrets and variables, and a task token with access to the private repository. The issue widens what the restricted token can reach; it gives nothing beyond what the owner's full account can already do.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-863"],"references":["https://blog.gitea.com/release-of-28.3.0/","https://github.com/go-gitea/gitea/pull/39690","https://github.com/go-gitea/gitea/pull/39853","https://github.com/go-gitea/gitea/releases/tag/v28.3.0","https://github.com/go-gitea/gitea/security/advisories/GHSA-qcgm-ggp8-22qc"],"reference_tags":[{"url":"https://blog.gitea.com/release-of-28.3.0/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39690","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39853","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.3.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-qcgm-ggp8-22qc","tags":[]}],"products":[],"affected":[],"source":"nvd","synced_at":"2026-11-01T10:34:16.358491727+00:00"},"epss":{"cve":"CVE-2026-116289","score":0.00198,"percentile":0.09603,"date":"2026-11-01"},"kev":null,"exploits":[],"weaknesses":[{"name":"Incorrect Authorization","common_name":null,"deprecated":false,"replaced_by":[],"id":"CWE-863"}],"osv":[],"fixed":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
