Vier kwetsbaarheden zijn als kritiek aangemerkt en kunnen zonder authenticatie en gebruikersinteractie op afstand worden misbruikt.\n\nDe kwetsbaarheid met kenmerk CVE-2026-10747 heeft een CVSS-score van 10,0 en betreft een heap-based buffer overflow in IBM MQ. De kwetsbaarheden met kenmerk CVE-2026-79724, CVE-2026-85025 en CVE-2026-81204 hebben een CVSS-score van 9,8 en bevinden zich in Langflow OSS. Een niet-geauthenticeerde kwaadwillende kan deze kwetsbaarheden misbruiken om willekeurige code of OS-commando's uit te voeren.
