Description
Renovate before 44.60.1 contains an allowlist bypass vulnerability that allows repository users to evade the allowedHeaders restriction by placing hostRules headers inside shared presets. Attackers can supply internal or externally sourced presets with unvalidated hostRules[].headers to inject custom HTTP headers into requests Renovate sends to other hosts.
