About this source
CISA's Industrial Control Systems team publishes vulnerability advisories specifically for OT, ICS, SCADA, and critical infrastructure software: Siemens, Schneider Electric, Rockwell Automation, ABB, Honeywell, Emerson, GE Digital, plus the supporting protocols. Around 65 advisories a month, each with a CVSS score, affected products, mitigation guidance, and where applicable a Known Exploited Vulnerabilities Catalog entry. ICS advisories are higher-stakes than general IT vulns: a CVSS 7 in a PLC firmware can mean physical safety risk in a factory or grid asset. Watch this if you secure industrial networks, run a SOC for a manufacturer, or advise critical infrastructure operators. GovPing publishes each advisory with the affected vendor, CVSS, and CISA link.
What changed
CISA ICS-CERT released an advisory identifying a weak authentication vulnerability (CVE-2025-70994) in Yadea T5 Electric Bicycles, scoring 7.3 on the CVSS v3 scale. The vulnerability allows an attacker to unlock and start the bicycle, creating a vehicle theft vector. All versions of the T5 Electric Bicycle are affected. Organizations operating these devices in transportation systems critical infrastructure should review CISA's recommended mitigation practices and monitor for any updates.
