CVE-2026-110868: Server-Side Request Forgery (SSRF) in renovatebot renovate
Description
Renovate versions prior to 44.79.0 contain a server-side request forgery (SSRF) vulnerability.

Technical Analysis
CVE-2026-110868 is an SSRF vulnerability in renovatebot's Renovate product affecting versions before 44.79.0. The vulnerability arises because the shared HTTP client can be manipulated to request arbitrary internal URLs through configuration options such as extends presets or customDatasources. This can be exploited to access sensitive internal endpoints like instance metadata services, potentially exposing AWS credentials or other sensitive data via logs. The vulnerability is rated high severity (CVSS 8.4) and has an official patch available.
Potential Impact
Successful exploitation allows an attacker with limited privileges to make internal HTTP requests from the Renovate server, potentially accessing sensitive internal resources such as cloud instance metadata services. This can lead to credential disclosure (e.g., AWS credentials) and leakage of sensitive information through logs. The impact is significant given the potential for privilege escalation and data exposure.
Mitigation Recommendations
An official patch is available for this vulnerability. Users should upgrade Renovate to version 44.79.0 or later to remediate the SSRF issue. Since Renovate is a cloud service, the vendor manages remediation for the hosted service; users should verify with the vendor advisory for cloud-hosted instances. No additional mitigation steps are indicated in the advisory.
