{"cve":"CVE-2025-71424","nvd":{"published":"2026-09-27T02:17:16.393","modified":"2026-10-14T13:10:00.187","status":"Deferred","description":"Contrast, Edgeless Systems' runtime for confidential containers on Kubernetes, is affected in versions up to and including 1.9.0. The VOLUME directive in a Dockerfile (config.volumes in the OCI image configuration) is only a hint and is not handled specially by Kubernetes, but containerd adds a mount point for it when Kubernetes sets none, requiring the runtime to be able to push arbitrary data to the Kata agent. As a result, on bare-metal Contrast deployments (AKS deployments are not affected) that run an image declaring at least one VOLUME for which no Kubernetes mount exists at that path, the untrusted host can write arbitrary file trees below that mount point inside the confidential container, compromising the integrity of a directory that is typically important to the application's core functionality. Version 1.9.1 fixes the issue by disallowing this configuration in `contrast generate`.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":3.5},"cwes":["CWE-693"],"references":["https://github.com/edgelesssys/contrast/security/advisories/GHSA-phhq-63jg-fp7r","https://www.vulncheck.com/advisories/edgeless-systems-contrast-before-1.9.1-insecure-volume-mount"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2025-71424","score":0.00163,"percentile":0.05502,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-phhq-63jg-fp7r","url":"https://osv.dev/vulnerability/GHSA-phhq-63jg-fp7r","summary":"Contrast vulnerability allows arbitrary host data Injection into container VOLUME mount points","modified":"2026-09-27T11:55:50.735097148Z","packages":[{"ecosystem":"Go","name":"github.com/edgelesssys/contrast","purl":"pkg:golang/github.com/edgelesssys/contrast","ranges":["<1.9.1"],"fixed":["1.9.1"]}]},{"id":"GO-2025-3807","url":"https://osv.dev/vulnerability/GO-2025-3807","summary":"Contrast vulnerability allows arbitrary host data Injection into container VOLUME mount points in github.com/edgelesssys/contrast","modified":"2026-09-27T11:55:50.735097148Z","packages":[{"ecosystem":"Go","name":"github.com/edgelesssys/contrast","purl":"pkg:golang/github.com/edgelesssys/contrast","ranges":["<1.9.1"],"fixed":["1.9.1"]}]}],"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).
