De kwetsbaarheid stelt een kwaadwillende in staat om middels een malafide bericht een NTLM-authenticatie te initi\u00ebren naar een server onder controle van de kwaadwillende, waarmee de kwaadwillende authenticatiegegevens kan bemachtigen. Er is (nog) geen publieke Proof-of-Concept-code beschikbaar en misbruik vereist een speciaal ingerichte server. Grootschalig misbruik is hiermee niet waarschijnlijk.\n\n```\nMicrosoft Office Word: \n|----------------|------|-------------------------------------|\n| CVE-ID         | CVSS | Impact                              |\n|----------------|------|-------------------------------------|\n| CVE-2026-21514 | 7.80 | Omzeilen van beveiligingsmaatregel  | \n|----------------|------|-------------------------------------|\n\nMicrosoft Office Excel: \n|----------------|------|-------------------------------------|\n| CVE-ID         | CVSS | Impact                              |\n|----------------|------|-------------------------------------|\n| CVE-2026-21259 | 7.30 | Verkrijgen van verhoogde rechten    | \n| CVE-2026-21258 | 5.50 | Toegang tot gevoelige gegevens      | \n| CVE-2026-21261 | 5.50 | Toegang tot gevoelige gegevens      | \n|----------------|------|-------------------------------------|\n\nMicrosoft Office Outlook: \n|----------------|------|-------------------------------------|\n| CVE-ID         | CVSS | Impact                              |\n|----------------|------|-------------------------------------|\n| CVE-2026-21260 | 7.50 | Voordoen als andere gebruiker       | \n| CVE-2026-21511 | 7.50 | Voordoen als andere gebruiker       | \n|----------------|------|-------------------------------------|\n```",
