"statement": "This Important flaw in Tekton Pipelines allows an authenticated user to achieve arbitrary code execution on the resolver pod by injecting malicious commands into the git resolver's revision parameter. This vulnerability happens because the `revision` parameter is passed as a positional argument to the `git fetch` command without any previous validation whether the parameter's value doesn't start with `-` character. Combining this lack of validation with the fact the function which validates the repository URL explicitly allows a repository URL to being with `/`, translating to a local filesystem. An attacker with enough privileges to perform an operation which trigger resolvers to use the `ResolutionRequest` function can \nchain both behaviors to trick Tekton Pipelines to load and execute an arbitrary binary on the resolver pod.\nExploring this vulnerability may be considered of a high complexity as an attacker needs to either know an existing valid git repository located at a predicable path already in the resolver pod or a default URL configuration pointing to a local filesystem's path.\nA successful exploitation of the flaw can lead to the exfiltration of all cluster-wide secrets, posing a significant risk to the integrity and confidentiality of the OpenShift environment. Additionally, depending on the data included in the `kubeconfig` files, an attacker may achieve privilege escalation or perform lateral movements within the targeted cluster.", "threat_severity": "Important"}

An attacker who can submit a ResolutionRequest can therefore inject arbitrary git flags, such as --upload-pack, into the fetch call. Coupled with the validateRepoURL function that permits URLs starting with a slash, this permits chaining the injection of a binary name that will be executed on the resolver pod. Because the resolver runs under the tekton-pipelines-resolvers ServiceAccount, which has cluster-wide get/list/watch permissions on all Secrets, even a single successful exploit leads to full cluster-wide secret exfiltration. This flaw is a Remote Code Execution vulnerability and is identified as CWE-88.", "risk_and_exploitability": "The CVSS score of 7.5 indicates a high severity risk of arbitrary code execution. No EPSS score is presently available, so the exact exploitation probability cannot be quantified. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires the capability to create or modify a ResolutionRequest, which can be achievable in multi-tenant or permissively configured namespaces. Successful exploitation results in the attacker gaining broad cluster access to Secrets via the resolver pod."}}}}, "created": "2026-04-22T03:45:06.831494+00:00", "updated": "2026-04-22T06:30:10.674198+00:00", "vendors": ["tektoncd", "tektoncd$PRODUCT$pipeline"]}
