An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-6866 in the wild and no public exploit code.\n\nAffected product: Schneider Electric EcoStruxure™ Panel Server. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-6866/ (Markdown: https://insights.sbomify.com/CVE-2026-6866/index.md)","id":"CVE-2026-6866","markdown":"https://insights.sbomify.com/CVE-2026-6866/index.md","name":"CVE-2026-6866","record":{"aliases":["GHSA-rp4q-4mm5-p2vx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"EcoStruxure Panel Server","requires_auth":"none","summary":"Attackers can access sensitive data and authenticate using known default credentials if the system reverts to initial settings.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"ecostruxure_panel_server_pas400_firmware","vendor":"schneider-electric"},{"product":"ecostruxure_panel_server_pas600_firmware","vendor":"schneider-electric"},{"product":"ecostruxure_panel_server_pas600v2_firmware","vendor":"schneider-electric"},{"product":"ecostruxure_panel_server_pas800_firmware","vendor":"schneider-electric"},{"product":"ecostruxure_panel_server_pas800v2_firmware","vendor":"schneider-electric"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"CWE-1188 Initialization of a Resource with an Insecure Default vulnerability exists that could cause unauthorized disclosure of sensitive information when credentials revert to initial settings in rare circumstances, enabling unauthorized authentication using known credentials.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Initialization of a Resource with an Insecure Default vulnerability on EcoStruxure™ Panel Server","id":"CVE-2026-6866","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improperly Controlled Sequential Memory Allocation in Wireshark","id":"CVE-2026-6867"},"packages":[],"prev":{"headline":"Improper Limitation of a Pathname to a Restricted Directory Vulnerability on Multiple Products","id":"CVE-2026-6865"},"products":["EcoStruxure™ Panel Server"],"published":"2026-05-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-05-12","vendors":["Schneider Electric"]},"summary":"Attackers can access sensitive data and authenticate using known default credentials if the system reverts to initial settings.","url":"https://insights.sbomify.com/CVE-2026-6866/"}
