A vulnerability has been found in PicoTronica e-Clinic Healthcare System ECHS 5.7. This affects an unknown function of the file /cdemos/echs/api/v2/ of the component Response Header Handler. Such manipulation leads to information disclosure. The attack may be performed from remote. The exploit has been disclosed to the public and may be used. Upgrading to version 5.7.1 mitigates this issue. It is suggested to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
A vulnerability was identified in CodeAstro Online Job Portal 1.0. The impacted element is an unknown function of the file /jobs/job-delete.php of the component Delete Job Posting Handler. Such manipulation of the argument ID leads to improper access controls. The attack can be launched remotely. The exploit is publicly available and might be used.
A improper access control vulnerability in Fortinet FortiClientEMS 7.4.5 through 7.4.6 may allow an unauthenticated attacker to execute unauthorized code or commands via crafted requests.
A flaw in Node.js's permission model allows Unix Domain Socket (UDS) connections to bypass network restrictions when `--permission` is enabled. Even without `--allow-net`, attacker-controlled inputs (such as URLs or socketPath options) can connect to arbitrary local sockets via net, tls, or undici/fetch. This breaks the intended security boundary of the permission model and enables access to privileged local services, potentially leading to privilege escalation, data exposure, or local code execution. * The issue affects users of the Node.js permission model on version v25. In the moment of this vulnerability, network permissions (`--allow-net`) are still in the experimental phase.
Certain system functions may be accessed without proper authorization, allowing attackers to start, stop, or delete installed applications, potentially disrupting system operations.

Improper link resolution before file access ('link following') in Microsoft Defender allows an authorized attacker to elevate privileges locally.
Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Exchange Server allows an unauthorized attacker to perform spoofing over a network.
An Improper Input Validation in Ivanti EPMM before versions 12.6.1.1, 12.7.0.1, and 12.8.0.1 allows a remotely authenticated user with administrative access to achieve remote code execution.
OpenClaw before 2026.4.22 contains a server-side request forgery vulnerability in the Zalo plugin's sendPhoto function that fails to validate outbound photo URLs through the SSRF guard. Attackers can bypass SSRF protection by providing malicious photo URLs to the Zalo Bot API, enabling unauthorized access to internal resources.
OpenClaw before 2026.4.22 contains an exec allowlist analysis vulnerability allowing shell expansion hiding in unquoted heredoc bodies. Attackers can bypass allowlist validation by embedding shell expansion tokens in heredoc bodies to execute unapproved commands at runtime.
