Summary
Clarifies the documented Redis ACL behavior for
GRAPH.RO_QUERYin FalkorDB v6.0.2.Problem
The existing ACL documentation recommends
%R~*for read-only graph access. However, users can encounterNOPERM No permissions to access a keywhen executingGRAPH.RO_QUERYwith read-only key permissions.Related issue: FalkorDB/FalkorDB#3356
Changes
app2:*.ACL DRYRUN.Verification
Validated the ACL-selector workaround against FalkorDB v6.0.2 in Docker using a disposable test graph and restricted user.
ACL SETUSER reader3356 reset on >test3356pass +PING +INFO (~app2:* +GRAPH.RO_QUERY)returnedOK.ACL DRYRUN reader3356 GRAPH.RO_QUERY app2:users "MATCH (n) RETURN count(n)"returnedOK.ACL DRYRUN reader3356 GRAPH.QUERY app2:users "CREATE (:Unauthorized)"denied access toGRAPH.QUERY.GRAPH.RO_QUERYexecuted successfully and returnedcount(n) = 1.These results confirm the documented selector approach for this tested configuration. They do not fix the underlying
%R~*read-only key-specification issue.Scope
This is a documentation-only change. It does not modify the underlying Redis command key specifications or resolve the implementation bug.
