CVE-2026-47690

HIGHPre-NVD 7.57.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 57% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

MeltanoHub is the source code for hub.meltano.com, the central place for Meltano plugins. Versions of the repo prior to commit 923820de8f64d753951fbbd54f7282a3d5f75173 were vulnerable to exfiltration of GITHUB_TOKEN with write permissions to the repository. The vulnerable workflow used pull_request_target, which runs in the context of the base repository with access to secrets. Commit 923820de8f64d753951fbbd54f7282a3d5f75173 fixes the issue. No known workarounds are available.
