CVE-2026-97865Network attack vector

Unauthenticated queue manipulation via unrestricted property writes

Published Sep 25, 2026 · Updated Sep 25, 2026

Improper input validation in Open Web Analytics 1.8.0 through 1.8.1 allows remote attackers to alter remote-queue bookkeeping. Event::loadFromArray copies every matching request-array property into an Event, letting queue.php overwrite receiver-controlled identifiers, retry counts, and scheduling fields. The endpoint is disabled by default and accepts only allowlisted event types when enabled; the upstream maintainer states that request data never reaches unserialize and does not enable code execution.
