Summary
CVE-2026-47833 is a privilege escalation vulnerability from container to host via manipulation of the bpm.log file. A compromised process inside a bpm container can force the system to change the owner of any host file, leading to the exposure of passwords from the /etc/shadow file.
Risk Assessment
This vulnerability poses a serious threat to data confidentiality within the organization, allowing an attacker to access user passwords on the host. Every bpm-managed service is at risk.
Recommendation
It is recommended to upgrade to version v1.4.30 or later to mitigate this vulnerability. Additionally, it is advisable to review and restrict the permissions of processes running in containers.

Original NVD description (English source)
setupBpmLogs follows symlink for bpm.log open and chown — container-to-host privilege escalation via /etc/shadow. A compromised process inside a bpm container can cause root to chown an arbitrary host file to vcap and append bpm JSON log lines to it. The chown alone lets the attacker take ownership of /etc/shadow and read every password hash on the host via the read-only /etc bind mount. This is a container-to-host confidentiality break affecting every bpm-managed job. Affected versions: bpm-release, all versions prior to v1.4.30.
