An issue was discovered in exceptionwrapper.py in OpenStack Nova 13.x through 13.1.3, 14.x through 14.0.4, and 15.x through 15.0.1. Legacy notification exception contexts appearing in ERROR level logs may include sensitive information such as account passwords and authorization tokens.
By rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova Filter Scheduler are affected.
Affected versions: <=14.0.9, >=15.0.0 <=15.0.7, >=16.0.0 <=16.0.2
