iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. Versions prior to 2.3.1.2 have a Type Confusion vulnerability in `CIccProfileXml::ParseBasic()` at `IccXML/IccLibXML/IccProfileXml.cpp`. This vulnerability affects users of the iccDEV library who process ICC color profiles. Version 2.3.1.2 contains a patch. No known workarounds are available.
Pexip Infinity 38.0 and 38.1 before 39.0 has insufficient access control in the RTMP implementation, allowing an attacker to disconnect RTMP streams traversing a Proxy Node.
A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15.7.2, macOS Tahoe 26.1, macOS Sonoma 14.8.2. An app with root privileges may be able to access private information.
Incomplete authorization of linked device synchronization messages in WhatsApp for iOS prior to v2.25.21.73, WhatsApp Business for iOS v2.25.21.78, and WhatsApp for Mac v2.25.21.78 could have allowed an unrelated user to trigger processing of content from an arbitrary URL on a target’s device. We assess that this vulnerability, in combination with an OS-level vulnerability on Apple platforms (CVE-2025-43300), may have been exploited in a sophisticated attack against specific targeted users.
IBM Jazz Foundation 7.0.2 to 7.0.2 iFix035, 7.0.3 to 7.0.3 iFix018, and 7.1.0 to 7.1.0 iFix004 could allow an unauthenticated remote attacker to update server property files that would allow them to perform unauthorized actions.

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.
