Affected devices do not properly handle high-volume multicast network traffic, which can exhaust available memory resources in the affected application. This could allow an unauthenticated attacker on the local network segment to cause a denial-of-service condition of the affected application. The affected application becomes inaccessible and requires a manual restart; no project data is lost. Successful exploitation requires a specific project configuration to be already active on the targeted instance.<\/p>\n<p>  Severity: 7.4 | HIGH<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-54429 Published : July 14, 2026, 10:16 a.m. | 1\u00a0hour, 14\u00a0minutes ago Description :A vulnerability has been identified in SIMATIC S7-PLCSIM Advanced (All versions).
