CVE-2026-47734

Dulwich prior to 1.2.5 is vulnerable to an unbounded memory allocation in receive-pack when processing a crafted thin pack. A tiny push (~174 bytes) can declare a huge dest_size in the delta header, causing add_thin_pack / apply_delta to allocate hundreds of MB regardless of actual data. Impacted...
