A user who can run a workflow could use the job's token with `GET /api/v1/user/repos` to list every repository on the instance, including private repositories of other users and organizations, with their metadata. Repository contents remained protected by per-repository permission checks. System users now own nothing, and `/api/v1/user` routes other than `GET /api/v1/user` accept only individual and bot accounts.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-200","CWE-862"],"references":["https://blog.gitea.com/release-of-28.3.0/","https://github.com/go-gitea/gitea/pull/39945","https://github.com/go-gitea/gitea/pull/40115","https://github.com/go-gitea/gitea/releases/tag/v28.3.0","https://github.com/go-gitea/gitea/security/advisories/GHSA-8r36-6j2c-3gmv"],"reference_tags":[{"url":"https://blog.gitea.com/release-of-28.3.0/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39945","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/40115","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.3.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8r36-6j2c-3gmv","tags":[]}],"products":[],"affected":[],"source":"nvd","synced_at":"2026-11-01T10:34:16.358491727+00:00"},"epss":{"cve":"CVE-2026-112887","score":0.00185,"percentile":0.08096,"date":"2026-11-01"},"kev":null,"exploits":[],"weaknesses":[{"name":"Exposure of Sensitive Information to an Unauthorized Actor","common_name":null,"deprecated":false,"replaced_by":[],"id":"CWE-200"},{"name":"Missing Authorization","common_name":null,"deprecated":false,"replaced_by":[],"id":"CWE-862"}],"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).
