fix(deps): bump jackc/pgx/v5 to v5.9.0 (CVE-2026-33816)#48
Merged
Conversation
Memory-safety vulnerability in pgproto3 (Backend.Receive() and FunctionCall.Decode()), exploitable via malformed protocol messages. CVSS 9.8 (Critical) — network-exploitable, no auth required. Fixed in v5.9.0. pgx v5.9.0's go.mod declares `go 1.25.0`, so the go directive bumps in turn (1.24.0 -> 1.25.0). The toolchain go1.24.3 line drops because the go directive now matches a stable release. Refs https://nvd.nist.gov/vuln/detail/CVE-2026-33816, https://pkg.go.dev/vuln/GO-2026-4772
