——7The egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains an uncontrolled format string vulnerability. The -gp (glyph pattern) command-line option is used directly as the format string for sprintf() with only a single argument supplied. If an attacker provides additional format specifiers, egg-mkfont may read unintended stack values and write the formatted output into generated .egg and .png files, resulting in disclosure of stack-resident memory and pointer values.3d CVE-2026-156807.5 ALT

——5Lorex 2K Indoor Wi-Fi Security Camera CDeviceOperator Format String Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Lorex 2K Indoor Wi-Fi Security Cameras. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of JSON requests in the sonia binary. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-25884.3d CVE-2026-464655.5 MED

——1A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable.1d
