CVE-2026-76139
HighCVSS 8.0Exploitation Probability (EPSS)
Elevated risk54th percentile - higher than 54% of all known CVEs
Summary
A flaw was found in acm-operator-bundle. The build process downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.
Risk Assessment
The risk includes unauthorized access to credentials and build resources, which could compromise the integrity and confidentiality of the delivered software.
Recommendation
Immediately review the build process, verify the integrity of downloaded scripts, and implement signing and source verification mechanisms.
