  • Sep 9, 2026Snipe-IT before 8.7.0 does not apply the CheckUserIsActivated middleware to the `api` middleware group in app/Http/Kernel.php, and deactivating a user does not CVE-2026-86762 · Other software · grokability · reported by VulnCheckHigh 8.6

    Snipe-IT before 8.7.0 does not apply the CheckUserIsActivated middleware to the `api` middleware group in app/Http/Kernel.php, and deactivating a user does not revoke that user's Passport personal access tokens. As a result, although a deactivated account is correctly refused at web login, its existing API token continues to authenticate and to grant read and write access to the REST API (assets, users, licenses, etc.) at the account's prior permission level until the token expires. A deactivated account that retains user-management permissions can re-activate itself through the API, permanently defeating the deactivation control.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
