Apple addresses Screen Sharing vulnerability Earlier today, Apple released macOS Sonoma 14.8.9, macOS Sequoia 15.7.9, and macOS Tahoe 26.6.1, with the release notes for all three saying only that they provided “important security fixes” and were recommended for all users. Apple has now updated its security releases page with details of the vulnerability addressed by the updates. CVE-2026-65400: Alfredo Pesoli (@__rev) via Bynario Atlas (bynar.io) While there is no indication that the bug was exploited in the wild, Apple’s description suggests that an attacker could bypass Screen Sharing’s authentication checks and remotely access a vulnerable Mac.
