renovate: Server-Side Request Forgery
CVE-2026-110868 is a high-severity server-side request forgery vulnerability in renovate from Renovatebot, with a CVSS 3.1 base score of 8.5 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 44.79.0 as the first without the flaw, so updating renovate to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.18% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update renovate to 44.79.0 or a later version.
- Update renovate-ce to 15.6.0 or a later version.
- Update renovate-ee-server to 15.6.0 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.

Official description
Renovate before 44.79.0 contains a server-side request forgery vulnerability that allows users to make the shared HTTP client request arbitrary internal URLs via extends presets or customDatasources. Attackers can point a preset at an instance metadata service endpoint to obtain AWS credentials or leak sensitive information through Renovate logs.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Server-Side Request Forgery
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
How developers prevent this class of flaw
- If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
- If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
