CVE-2026-62906 is an improper neutralization of special elements in data query logic (CWE-943, an SQL-injection-style flaw) in Microsoft Discovery Studio that allows an unauthorized attacker to disclose information over a network. It is remotely exploitable without authentication (AV:N/PR:N) but requires user interaction (UI:R), meaning a user must perform some action, such as clicking a crafted link or submitting crafted input, for the attack to succeed. Successful exploitation has a high impact on confidentiality, potentially exposing sensitive data, while integrity and availability are unaffected. Any organization running Microsoft Discovery Studio is potentially affected, and Microsoft addressed the issue as part of the September 2026 Patch Tuesday security updates. There is currently no known public proof-of-concept, no inclusion in CISA's Known Exploited Vulnerabilities catalog, and EPSS estimates only a 0.7% probability of exploitation in the next 30 days, so no active exploitation is known at this time.
What to do: Apply the Microsoft September 2026 Patch Tuesday security updates for Discovery Studio as soon as possible and verify your inventory for deployments of the product, including which users have access. Because exploitation requires user interaction, advise users to avoid clicking unexpected links or submitting unsolicited input while patching is in progress, and monitor Microsoft's advisory for any expanded guidance.
