Hi,

Has the database structure changed between 5.19 and 5.20 ? We experience a regressions issue and want to try to rollback to 5.19

Is the regression we encounter linked to this fix ?

Fix command injection vulnerability in exec commands with ${option.name}

Fixed a critical command injection vulnerability in exec commands where shell control characters in job option values were not properly escaped, now protecting against malicious input by applying shell escaping to all ${option.name} values by default while providing a compatibility flag for edge cases.

The command which now fails is :

sudo -s su - ${node.db2RefInstanceUser} -c "'/workdb2/scripts/backup/men_backup.sh ${node.db2RefInstanceUser} ${node.db2RefDatabase} FNET Q'"
