Summary
Renovate is a dependency update automation tool. In versions before 44.11.2 (and Mend Renovate CE/EE images and charts before 15.4.0, and mend-renovate-enterprise-edition helm chart before 10.4.0), when listing new package versions from a NuGet registry Renovate follows pagination URLs supplied by the registry in the HTTP `Link` header without verifying that the target has the same origin as the configured registry. Registry credentials are attached to the request for the 'next' page, so a malicious or compromised NuGet registry can return a `Link` header pointing at an attacker-controlled server and cause Renovate to send the registry credentials to that server. Exploitation requires the remote registry to be malicious or compromised; such a registry would normally already have received the credentials on the initial request, so the issue primarily allows the credentials to be delivered to an additional, attacker-chosen host. The fix restricts pagination to the same origin; the previous behaviour can be re-enabled with the RENOVATE_X_NUGET_PAGINATION_ALLOW_CROSS_ORIGIN option.
Risk Assessment
Organizations using Renovate with NuGet registries are exposed to leakage of registry credentials to a malicious host, potentially leading to unauthorized access to the registry and its resources.
Recommendation
Update Renovate to version 44.11.2 or later (or corresponding Mend Renovate CE/EE and helm chart versions), or if not possible, avoid using untrusted NuGet registries.
Other vulnerabilities in Renovate
See all- CVE-2026-110868High
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. An attacker can point a preset at an instance metadata service endpoint to obtain AWS credentials or leak sensitive information through Renovate logs.
- CVE-2026-110867High
Renovate before 44.60.1 contains an allowlist bypass vulnerability that allows repositories to set restricted environment variables by placing env inside a shared preset. An attacker controlling an externally sourced preset can override variables like PATH, LD_PRELOAD, NODE_OPTIONS, or GIT_SSL_CAINFO in child processes on self-hosted instances.
- CVE-2026-110866Medium
Renovate before 44.61.3 contains a protection mechanism bypass vulnerability that allows minimumReleaseAge checks to be skipped when a user requests a PR rebase via the rebase/retry checkbox. Attackers who publish a malicious dependency version can have it pushed into the PR and run in CI before the required release age elapses.
- CVE-2026-110865High
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. An attacker can supply internal or externally sourced presets with unvalidated hostRules[].headers to inject custom HTTP headers into requests Renovate sends to other hosts.
- CVE-2026-88889High
Renovate before 44.14.7 contains a command injection vulnerability in the Maven Wrapper manager that allows attackers to execute arbitrary commands by specifying a malicious distributionType parameter in maven-wrapper.properties. Attackers can inject shell commands through unescaped distributionType values to achieve remote code execution when Renovate processes Maven Wrapper updates in binarySource=docker mode.
- CVE-2026-88888High
Renovate before 44.14.7 contains a command injection vulnerability in the Mix manager when processing private dependencies with unescaped organization parameters. Attackers can inject shell metacharacters through malicious package names to execute arbitrary commands as the Renovate user in binarySource=docker mode.
- CVE-2026-88887High
Renovate is a dependency update automation tool. When listing tags/digests for a container image, Renovate follows pagination links supplied by the remote registry in the HTTP Link header and attaches the registry credentials to the follow-up request without verifying that the pagination URL has the same origin as the original registry. A malicious or compromised container registry can therefore specify a Link header pointing to an attacker-controlled host and receive the credentials Renovate uses for that registry. Exploitation requires that the target has container (Docker) dependencies and is already interacting with the malicious or compromised registry. This is fixed in Renovate 44.11.2 (npm and renovate/renovate images), Mend Renovate CE/EE 15.4.0 and the mend-renovate-enterprise-edition Helm chart 10.4.0; the same-origin check can be disabled with RENOVATE_X_DOCKER_PAGINATION_ALLOW_CROSS_ORIGIN.
- CVE-2026-88886High
Renovate is a dependency update automation tool. In versions before 44.14.7 (and in Mend Renovate CE/EE distributions before 15.4.0, and the mend-renovate-enterprise-edition Helm chart before 10.4.0), the manager/gradle-wrapper module does not escape the distributionUrl value read from a repository's gradle/wrapper/gradle-wrapper.properties file before invoking the Gradle Wrapper CLI. In self-hosted deployments configured with binarySource=docker and allowedUnsafeExecutions=['gradleWrapper', ...], a repository that supplies a crafted distributionUrl (for example, appending a shell metacharacter and command) can cause arbitrary commands to be executed as the Renovate user when Renovate processes a Gradle Wrapper update. The issue is fixed in Renovate 44.14.7; as a workaround, remove 'gradleWrapper' from allowedUnsafeExecutions.
- CVE-2026-88885High
Renovate before 44.14.7 contains a command injection vulnerability in the gomod manager when processing unescaped depName parameters in import-path update commands with binarySource=docker mode. Attackers can inject shell metacharacters through malicious dependency names to execute arbitrary commands as the Renovate user during Go module major version updates with postUpdateOptions gomodUpdateImportPaths enabled.
- CVE-2026-88884Medium
Renovate versions before 44.3.1 (and Mend Renovate CE/EE images before 15.4.0, mend-renovate-ce Helm chart before 15.4.0, mend-renovate-enterprise-edition Helm chart before 10.4.0) do not apply the internal minimumReleaseAge (stability age) checks to digest updates. When a repository configures minimumReleaseAge and has dependencies with updateType=digest (e.g., GitHub Actions pinned to a commit SHA, Docker images, Go modules, NuGet packages), Renovate still opens a pull request for a newly published digest, marked only with a pending renovate/stability-days status check.
