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-2026-35556 in the wild and no public exploit code.\n\nAffected product: OpenPLC_V3. 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-2026-35556/ (Markdown: https://insights.sbomify.com/CVE-2026-35556/index.md)","id":"CVE-2026-35556","markdown":"https://insights.sbomify.com/CVE-2026-35556/index.md","name":"CVE-2026-35556","record":{"aliases":["GHSA-xgm5-hf6v-855x"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenPLC_V3","requires_auth":"none","summary":"Attackers can retrieve plaintext credentials from OpenPLC_V3 to access sensitive information and potentially take over accounts.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"openplc_v3_firmware","vendor":"openplcproject"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-256","name":"Plaintext Storage of a Password"}],"description":"OpenPLC_V3 is vulnerable to a Plaintext Storage of a Password vulnerability that could allow an attacker to retrieve credentials and access sensitive information.","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":"Plaintext storage of a password in OpenPLC_V3","id":"CVE-2026-35556","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improper neutralization of special elements in authentication components in Amazon Athena ODBC driver","id":"CVE-2026-35558"},"packages":[],"prev":{"headline":"Subnet Solutions PowerSYSTEM Center Incorrect Authorization","id":"CVE-2026-35555"},"products":["OpenPLC_V3"],"published":"2026-04-09","related":[{"cvss_score":9.2,"headline":"Initialization of a resource with an insecure default in OpenPLC_V3","id":"CVE-2026-28205","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":9,"headline":"Memory corruption in OpenPLC v3","id":"CVE-2024-34026","kev_date_added":null,"published":"2024-09-18"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-31630","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":8.7,"headline":"Missing Authorization in OpenPLC_V3","id":"CVE-2026-35063","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":7.5,"headline":"Denial of service in OpenPLC v3","id":"CVE-2024-36980","kev_date_added":null,"published":"2024-09-18"},{"cvss_score":7.5,"headline":"Denial of service in OpenPLC v3","id":"CVE-2024-36981","kev_date_added":null,"published":"2024-09-18"}],"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":"total"},"state":"PUBLISHED","updated":"2026-04-10","vendors":["OpenPLC_V3"]},"summary":"Attackers can retrieve plaintext credentials from OpenPLC_V3 to access sensitive information and potentially take over accounts.","url":"https://insights.sbomify.com/CVE-2026-35556/"}
