GHSA-557g-r22w-9wvx · Severity: high · Ecosystem: go — Incorrect Permission Assignment for Critical Resource in Singularity
An issue was discovered in Singularity 3.1.0 to 3.2.0-rc2, a malicious user with local/network access to the host system (e.g. ssh) could exploit this vulnerability due to insecure permissions allowing a user to edit files within `/run/singularity/instances/sing/<user>/<instance>`. The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host.
Conclusion & alert: CVE-2019-11328 is rated High Exploit Risk (79.5/100): CVSS High severity, with medium exploitation likelihood (EPSS 2.13%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +1.52% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
