During build operations, the component automatically downloads and executes a script from a remote location without performing integrity or authenticity validation. This flaw allows a remote attacker to achieve arbitrary code execution within the build environment. If exploited, an attacker can access sensitive build-time credentials, including GitHub access tokens and container registry passwords. Furthermore, this vulnerability facilitates the injection of malicious code into the final operator bundle, potentially leading to widespread compromise of downstream systems that deploy the affected software. Defenders should prioritize auditing build logs and restricting outbound network access from build pipelines to prevent the execution of untrusted external scripts.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability compromises the integrity of the build pipeline and the resulting acm-operator-bundle artifacts. Attackers gain access to sensitive credentials, enabling further unauthorized access to source code repositories and container registries. The potential for malicious payload injection into the operator bundle poses a critical risk to any infrastructure utilizing the affected component for deployment, as it provides a pathway for persistent, supply-chain-based access to production environments.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cp\u003ePrioritized actions include:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003eAudit build environment logs for unexpected outbound network connections initiated by build processes.\u003c/li\u003e\n\u003cli\u003eImplement strict egress filtering on CI/CD build nodes to allow downloads only from known, cryptographically verified internal or upstream repositories.\u003c/li\u003e\n\u003cli\u003eRevoke and rotate any GitHub access tokens or registry credentials that were present in build environments associated with affected versions of the acm-operator-bundle.\u003c/li\u003e\n\u003cli\u003eEnsure all scripts invoked during the build process are pinned by hash or retrieved from trusted, local, or proxied storage.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-08-19T22:40:04Z","date_published":"2026-08-19T22:40:04Z","id":"https://feed.craftedsignal.io/briefs/2026-08-cve-2026-76139/","summary":"CVE-2026-76139 allows attackers to perform remote code execution during the acm-operator-bundle build process by exploiting an unverified remote script download.","title":"Supply Chain Vulnerability in acm-operator-bundle","url":"https://feed.craftedsignal.io/briefs/2026-08-cve-2026-76139/"}],"language":"en","title":"CraftedSignal Threat Feed - Acm-Operator-Bundle","version":"https://jsonfeed.org/version/1.1"}
