Blinko through 1.8.8 contains a broken access control vulnerability in the /api/file route that allows authenticated users to read other users' private attachments due to a flawed owner check. Attackers can supply another user's stored filename, following a basename plus millisecond-timestamp pattern, to download private, non-shared attachments.

CVE-2026-937796.5 MÉD—
———The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.2 via the init_routes due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to read paid course lesson and topic content without enrollment, retrieve quiz answer keys including the is_correct field before attempting a quiz, and enumerate the email addresses, usernames, and registration data of other users including instructors and administrators. Exploitation requires that the attacker hold a valid Tutor LMS API key/secret pair, which is issued to subscriber-level users through the plugin's API key management feature.4hCVE-2026-174285.0 MÉD—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to improper authorization. Values supplied in the request URL are used in authorization decisions without sufficient verification, which could allow access to information belonging to others.4hCVE-2026-174058.8 ALT—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to broken object-level authorization. Access checks on keystore objects do not confirm that the requesting user is permitted to read them, which could expose keystore information.4hCVE-2026-173916.3 MÉD—
