CVE-2026-110865: Renovate before 44.60.1 HTTP Header Allowlist Bypass via Shared Presets

HighCVSS 7.1 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: mend mend-renovate-ce helm chart 15.5.0; mend mend-renovate-enterprise-edition helm chart 10.5.0; mend renovate-ce 15.5.0.

Low priority for now. Upgrade to mend mend-renovate-ce helm chart 15.5.0; mend mend-renovate-enterprise-edition helm chart 10.5.0; mend renovate-ce 15.5.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
