CVE-2026-46599: Golang.org/x/image Golang.org/x/image/tiff

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

The TIFF decoder does not place a limit on the size of PackBits-compressed data. A maliciously-crafted image can exploit this to cause a small image (both in terms of pixel width/height and encoded size) to make the decoder decode large amounts of compressed data.

Affected products

• Golang.org/x/image Golang.org/x/image/tiff: before 0.41.0 (fixed in 0.41.0)
