CVE-2026-18874
MediumCVSS 6.2Summary
A flaw was found in volsync-addon-controller. This vulnerability allows an attacker to inject malicious YAML (Yet Another Markup Language) code into the OpenShift Lifecycle Manager (OLM) Subscription resource. This is due to improper escaping of annotation values when they are rendered into YAML. Successful exploitation could lead to unauthorized modification or control over OLM Subscription configurations, potentially impacting software management within the cluster. This issue primarily affects systems where the 'volsync-addon-deploy-type: olm' annotation is explicitly enabled.
Risk Assessment
The risk includes the possibility of unauthorized modification of OLM configurations, potentially leading to integrity issues in software management and potential cluster takeover.
Recommendation
It is recommended to update volsync-addon-controller to a version containing the fix. Also, assess whether the 'volsync-addon-deploy-type: olm' annotation is necessary and restrict its use to trusted environments.
