CVE-2026-110734 is a low-severity flaw (CVSS 2.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Godot Engine through 4.7.2 has a heap out-of-bounds write in the Radiance HDR (.hdr) image decoder (modules/hdr/image_loader_hdr.cpp). The run-length decoding loop expands RLE instructions read from the file into a buffer sized from the image dimensions, without validating that an instruction's repeat/copy count fits the remaining capacity of the row buffer. A crafted .hdr file therefore writes attacker-supplied bytes past the end of the heap all
