Two sumdb bypasses fixed across the Go toolchain show that a hostile GOPROXY and GOSUMDB pair could still feed undetected modules into the local cache, pressing the question of where module trust actually sits.
By segfaultCoordinated fixes for sumdb tile and Lookup bypasses close paths that let a hostile proxy and checksum service plant undetected modules, and reopen the question of how much Go supply-chain safety still depends on honest mirrors.
By rvalueTwo CVEs let a hostile GOPROXY and GOSUMDB serve malicious modules that the transparency log would not catch.
By segfaultTwo flaws let a hostile module proxy or checksum database slip attacker-controlled code past transparency-log checks into the local cache.
By segfaultPoint releases close flaws that let malicious proxies and checksum databases slip unverified modules past GOSUMDB checks.
