What is CVE-2026-76858?
Netcore NR255-V version 1.5.130703 contains a stored cross-site scripting vulnerability in ddns_wan_list_show.cgi caused by unsafe eval() handling of DDNS data. Attackers can inject malicious script through the DDNS configuration path, leading to persistent execution when the affected page is viewed.

- CVE-2026-92248A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.7.8
