URL: https://github.com/apache/airflow/issues/55757
### Apache Airflow version
2.11.0
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
All our Astronomer's webserver that runs apache airflow changed status to
unhealthy from 12th of September. Recent logs show following error:
```
[2025-09-16T15:14:17.296+0000] {configuration.py:1237} WARNING - No module
named 'flask_limiter.wrappers'
```
We noticed that Flask-Limiter version got automatically updated from 3.12 to
3.13 by following dependencies:
```
flask-limiter==3.13
# via flask-appbuilder
flask-appbuilder==4.5.3
# via apache-airflow-providers-fab
apache-airflow==2.11.0
# via
# -c (workspace)
# apache-airflow-providers-amazon
# apache-airflow-providers-common-compat
# apache-airflow-providers-common-io
# apache-airflow-providers-common-sql
# apache-airflow-providers-fab
# apache-airflow-providers-ftp
# apache-airflow-providers-http
# apache-airflow-providers-imap
# apache-airflow-providers-microsoft-mssql
# apache-airflow-providers-sftp
# apache-airflow-providers-slack
# apache-airflow-providers-smtp
# apache-airflow-providers-snowflake
# apache-airflow-providers-sqlite
# apache-airflow-providers-ssh
# apache-airflow-providers-tableau
# astronomer-cosmos
```
Specifying `Flask-Limiter==3.12` in our pyproject.toml forces airflow to use
that version and solves the issue
### What you think should happen instead?
Flask's dependencies should be set in stone, so there are no unexpected
updates
### How to reproduce
Deploy specified airflow's version, webserver could have same errors
### Operating System
gitlab-runner 17.11.0
### Versions of Apache Airflow Providers
_No response_
### Deployment
Astronomer
### Deployment details
_No response_
### Anything else?
