CVE-2026-18453 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-09-09 7.5 High
A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.
CVE-2026-15398 2026-09-09 4.3 Medium
The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.1.22. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to bypass payment for paid events, fraudulently mark orders as completed, deplete ticket inventory, and trigger confirmation emails for tickets never purchased. This is exploitable by unauthenticated attackers because the wp_rest nonce is publicly emitted on every frontend page, and the order creation endpoint mints and returns an order_access_token to any caller possessing that nonce — giving unauthenticated users all credentials required to reach the privileged update_booking_status branch.
CVE-2025-71418 2026-09-09 5.3 Medium
PocketMine-MP versions before 5.25.2 fail to limit the explode() function in packet parsing, allowing malicious clients to waste server resources. Attackers can send crafted packets with excessive delimiters to consume CPU and memory through sign editing, JWT parsing, and command parsing endpoints.
CVE-2024-58382 1 Thephpleague 1 Commonmark 2026-09-09 7.5 High
league/commonmark versions before 2.6.0 contain polynomial time complexity vulnerabilities in Markdown parsing that allow attackers to cause denial of service. Attackers can submit carefully crafted Markdown inputs designed to trigger worst-case performance, and sending multiple requests in parallel exhausts CPU resources and PHP-FPM processes.
CVE-2023-54396 2026-09-09 6.5 Medium

CVE-2023-54390 2026-09-09 7.5 High
PocketMine-MP versions before 5.3.1 and 4.23.1 contain a denial of service vulnerability in LoginPacket JSON parsing due to improper null value handling in arrays. Attackers can send malformed JSON with unexpected null elements in LoginPacket to crash the server.
CVE-2022-51014 1 Pmmp 1 Pocketmine-mp 2026-09-09 6.5 Medium
PocketMine-MP before 4.0.7 contains an unhandled exception vulnerability in the ModalFormResponsePacket handler when processing malformed JSON from clients. Attackers can send specially crafted form response packets with invalid JSON to trigger an uncaught InvalidArgumentException, causing server crashes.
