CVE-2026-35480
CVE-2026-35480 affects the go-ipld-prime project, specifically the DAG-CBOR decoder. Prior to version 0.22.0, the decoder uses collection size hints from CBOR headers as preallocation hints for maps and lists without capping them or accounting for their cost in its allocation budget. This can lea...

go-ipld-prime 安全漏洞
go-ipld-prime is an implementation of the IPLD open-source specification interface. Versions of go-ipld-prime prior to 0.22.0 contained security vulnerabilities. These vulnerabilities stemmed from the DAG-CBOR decoder using the set size declared in the CBOR header as a hint for Go’s pre-allocatio...

CBORDecoder reuse can leak shareable values across decode calls
Summary When a CBORDecoder instance is reused across multiple decode operations, values marked with the shareable tag 28 persist in memory and can be accessed by subsequent CBOR messages using the sharedref tag 29. This allows an attacker-controlled message to read data from previously decoded...
