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.","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","score":7.1},"cvss_v3":null,"cwes":["CWE-20","CWE-664"],"references":["https://autonomylogic.com/","https://github.com/thiagoralves/OpenPLC_v3/pull/297/commits/095ee09623dd229b64ad3a1db38a901a3772f6fc","https://openplc.discussion.community/post/persistant-dos-affecting-openplc-runtime-13722844","https://www.vulncheck.com/advisories/openplc-runtime-v3-persistent-denial-of-service","https://openplc.discussion.community/post/persistant-dos-affecting-openplc-runtime-13722844"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-34226","score":0.00678,"percentile":0.52047,"date":"2026-10-26"},"kev":null,"osv":[],"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).
