CVE-2022-31045
Istio is an open platform to connect, manage, and secure microservices. In affected versions ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access resulting in undefined behavior or crashing. Users are most likely at risk if they have an Istio ingress Gateway exposed to external traffic. This vulnerability has been resolved in versions 1.12.8, 1.13.5, and 1.14.1. Users are advised to upgrade. There are no known workarounds for this issue.

Insufficient input validation in NetScaler ADC and NetScaler Gateway when configured as a SAML IDP leading to memory overread
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, the URBDRC client does not perform bounds checking on server‑supplied MSUSB_INTERFACE_DESCRIPTOR values and uses them as indices in libusb_udev_complete_msconfig_setup, causing an out‑of‑bounds read. This vulnerability is fixed in 3.20.1.
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a heap out-of-bounds read occurs in the smartcard SetAttrib path when cbAttrLen does not match the actual NDR buffer length. This vulnerability is fixed in 3.20.1.
In Area9 Rhapsode 1.47.3, an authenticated attacker can exploit the operation, url, and filename parameters via POST request to read arbitrary files from the server filesystem. Fixed in 1.47.4 (#7254) and further versions.
In AzeoTech DAQFactory release 20.7 (Build 2555), an Out-of-bounds Read vulnerability can be exploited by an attacker to cause the program to read data past the end of an allocated buffer. This could allow an attacker to disclose information or cause a system crash.

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.
