An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-71426 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/edgelesssys/contrast (Go): affected all versions; fixed in 1.4.1\n- github.com/edgelesssys/contrast (Go): affected all versions; fixed in 1.4.1\n- github.com/edgelesssys/contrast (Go): affected all versions; fixed in 1.4.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-71426/ (Markdown: https://insights.sbomify.com/CVE-2025-71426/index.md)","id":"CVE-2025-71426","markdown":"https://insights.sbomify.com/CVE-2025-71426/index.md","name":"CVE-2025-71426","record":{"aliases":["GHSA-m5hp-85q9-x6vh","GHSA-vqv5-385r-2hf8","GO-2025-3455"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Kubernetes confidential computing","requires_auth":"none","summary":"Attackers can impersonate coordinators to recover workload secrets if users fail to verify root CA certificates during recovery.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"Contrast is a confidential-computing runtime for Kubernetes. In versions before 1.4.1, a recovering Coordinator does not verify the seed supplied by the recovering party. An attacker can therefore stand up a rogue Coordinator whose manifest passes validation but whose secret seed is attacker-controlled. If network traffic is redirected from the legitimate Coordinator to the attacker's Coordinator, a workload owner can be impersonated when they either set a new manifest without comparing the returned root CA certificate against the existing one (the default behavior of the contrast CLI) or verify the Coordinator without comparing the root CA certificate against a trusted reference. Under these conditions the attacker can issue certificates that chain back to the rogue Coordinator's root CA and recover arbitrary workload secrets of workloads deployed after the attack. Secrets of the legitimate Coordinator (seed, workload secrets, CA), workload integrity, and certificates chaining to the mesh CA are not affected.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Contrast before 1.4.1 Coordinator Impersonation via Unauthenticated Recovery","id":"CVE-2025-71426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":3,"n_references":2,"next":{"headline":"Office-PowerPoint-MCP-Server through 2.0.7 Path Traversal via save_presentation and manage_image","id":"CVE-2025-71427"},"packages":[{"ecosystem":"Go","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"github.com/edgelesssys/contrast","purl":null,"source":"GHSA-vqv5-385r-2hf8"},{"ecosystem":"Go","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"github.com/edgelesssys/contrast","purl":"pkg:golang/github.com/edgelesssys/contrast","source":"GHSA-vqv5-385r-2hf8"},{"ecosystem":"Go","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"github.com/edgelesssys/contrast","purl":"pkg:golang/github.com/edgelesssys/contrast","source":"GO-2025-3455"}],"prev":{"headline":"Contrast before 1.8.1 Information Disclosure via Logging","id":"CVE-2025-71425"},"products":["contrast"],"published":"2026-09-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["edgelesssys"]},"summary":"Attackers can impersonate coordinators to recover workload secrets if users fail to verify root CA certificates during recovery.","url":"https://insights.sbomify.com/CVE-2025-71426/"}
