A security flaw has been discovered in NousResearch hermes-agent up to 2026.4.23. This affects the function _sync_anthropic_entry_from_credentials_file of the file agent/credential_pool.py of the component Credential Pool Synchronization. The manipulation results in improper authentication. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
The Slider Revolution plugin for WordPress in versions 6.0.0-6.7.55 and 7.0.0-7.0.14 is vulnerable to unauthorized modification of data. 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 Contributor-level access and above, to deactivate any active plugin installed on the site.
May 2026: This security advisory provides the details and fix information for a vulnerability that was discovered and fixed after the was disclosed in February 2026. This new advisory is for a new vulnerability in the control connection handshaking. The section of this advisory includes Show Control Connections guidance to help with system checks. A vulnerability in the peering authentication in Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, and Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative privileges on an affected system. This vulnerability exists because the peering authentication mechanism in an affected system is not working properly. An attacker could exploit this vulnerability by sending crafted requests to the affected system. A successful exploit could allow the attacker to log in to an affected Cisco Catalyst SD-WAN Controller as an internal, high-privileged, non-root user account. Using this account, the attacker could access NETCONF, which would then allow the attacker to manipulate network configuration for the SD-WAN fabric.
OpenClaw before 2026.4.10 contains an incomplete navigation guard vulnerability that allows attackers to trigger navigation without complete SSRF policy enforcement. Browser press/type style interactions, including pressKey and type submit flows, can bypass post-action security checks to execute unauthorized navigation.
Craft Commerce is an ecommerce platform for Craft CMS. In versions 4.0.0 through 4.10.2 and 5.0.0 through 5.5.4, the PaymentsController::actionPay discloses some order data to unauthenticated users when an order number is provided and the email check fails during an anonymous payment. The JSON error response includes the serialized order object (order), which contains some sensitive fields such as customer email, shipping address, and billing address. The frontend payment flow's actionPay() retrieves orders by number before authorization is fully enforcedLoad order by number. This issue has been fixed in versions 4.11.0 and 5.6.0.

ipmi-oem in FreeIPMI before 1.16.18 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Two subcommands "ipmi-oem dell get-active-directory-config" and "ipmi-oem fujitsu get-sel-entry-long-text" were found to have exploitable buffer overflows on response messages.

A vulnerability was detected in SourceCodester Online Food Ordering System 2.0. Affected by this issue is the function include of the file /index.php. The manipulation of the argument page results in file inclusion. The attack can be launched remotely. The exploit is now public and may be used.
alf.io is an open source ticket reservation system for conferences, trade shows, workshops, and meetups. Prior to version 2.0-M5-2606, a sandbox escape vulnerability in the alf.io extension script engine allows an authenticated administrator to execute arbitrary operating system commands on the server. The extension system is intended to execute restricted JavaScript in a sandboxed Rhino environment; however, a combination of an unguarded injected Java object (`returnClass`) and an incomplete AST blocklist allows the sandbox to be fully escaped using Java reflection without triggering any validation errors. Version 2.0-M5-2606 patches the issue.
