Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the str.lstrip function used for validating JWT tokens against Dag IDs. An attacker can gain unauthorized access to other Dags' log data by crafting JWT tokens that exploit character overlap in Dag names.
Note: This is only exploitable if the deployment relies on per-Dag log-access scoping, such as in multi-team, shared-executor, or shared-worker topologies.
