CVE-2026-9267 is an out-of-bounds read vulnerability in the check_server_certificate() function of Eclipse tinydtls before commit b3efd41ad111a4920f599f51ffa4f5e9f1e72221. This vulnerability allows unauthenticated attackers to trigger reads beyond valid buffer boundaries by crafting a Certificate handshake message with a specific fragment_length value. The vulnerability is caused by missing buffer length [truncated]
CVE-2026-4983 is a stored cross-site scripting (XSS) vulnerability in the Open VSX Registry. The vulnerability arises from the lack of sanitization of SVG files uploaded as extension icons before they are stored.

This issue was published on June 18, 2026, and has a CVSS score of 5.2. Users of affected versions should take immediate action to miti [truncated]
CVE-2026-2587 describes a critical server-side Expression Language (EL) injection issue in a Glassfish-related gadget handling path. The supplied description indicates that untrusted values from .xml input are evaluated without proper sanitization or escaping, and a test payload such as #{7*7} returns 49, confirming server-side expression evaluation. The reported impact is severe: remote attackers may be [truncated]
CVE-2026-2586 is a critical authenticated remote code execution issue in GlassFish’s Administration Console. The supplied record says a user with access to the panel can send crafted requests that lead to arbitrary operating system command execution under the privileges of the application service user. Because exploitation requires high privileges but no user interaction, and the impact spans confidential [truncated]
