After a successful malformed upload the runtime continues to operate until a restart; on restart the runtime can fail to start because of corrupted database entries, resulting in persistent denial of service requiring complete rebase of the product to recover. This vulnerability was remediated by commit 095ee09.","published_at":"2025-10-03T15:36:03.516000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.1,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-664","CWE-20"],"nvd_references":["https://autonomylogic.com/","https://openplc.discussion.community/post/persistant-dos-affecting-openplc-runtime-13722844","https://github.com/thiagoralves/OpenPLC_v3/pull/297/commits/095ee09623dd229b64ad3a1db38a901a3772f6fc","https://www.vulncheck.com/advisories/openplc-runtime-v3-persistent-denial-of-service"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:26:31.310434Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"autonomy-logic","vendor_name":"Autonomy Logic","product_slug":"openplc-runtime","product_name":"OpenPLC Runtime","version_start":"3.0","version_start_inclusive":true,"version_end":"095ee09623dd229b64ad3a1db38a901a3772f6fc","version_end_inclusive":false,"cpe23_uri":"cve5:autonomy-logic:openplc-runtime:3.0:095ee09623dd229b64ad3a1db38a901a3772f6fc"}],"exploit_refs":[],"news":[],"references":[{"url":"https://autonomylogic.com/","source_type":"MISC","tags":[]},{"url":"https://openplc.discussion.community/post/persistant-dos-affecting-openplc-runtime-13722844","source_type":"MISC","tags":[]},{"url":"https://github.com/thiagoralves/OpenPLC_v3/pull/297/commits/095ee09623dd229b64ad3a1db38a901a3772f6fc","source_type":"PATCH","tags":["patch"]},{"url":"https://www.vulncheck.com/advisories/openplc-runtime-v3-persistent-denial-of-service","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2025-10-03T15:36:03.516000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:45:12.189729Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:45:12.189729Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:45:12.189729Z","label":"CVSS score revised","source":"cvelistv5"}]}
