False positives when proxying Immich
What happened?
time="2025-04-04T16:08:49Z" level=info msg="Ban for IPV4 whitelisted, reason [Immich whitelisted]" id=late-wood name=user/whitelist_immich stage=s01-whitelist
time="2025-04-04T16:08:49Z" level=info msg="Ip IPV4 performed 'crowdsecurity/http-crawl-non_statics' (57 events over 8.425247495s) at 2025-04-04 16:08:48.97766958 +0000 UTC"
time="2025-04-04T16:08:49Z" level=info msg="[Ip IPV4 performed 'crowdsecurity/http-crawl-non_statics' (57 events over 8.425247495s) at 2025-04-04 16:08:48.97766958 +0000 UTC] is whitelisted, skip."
From the ban logs, the tagged action appears to be the /api/albums/6f798dd0-83a8-4dd1-b395-8f4b8a3c31b8 endpoints (various UUIDs)
I am not sure if this is the correct place to report, let me know if it needs to go somewhere else. I do have a whitelist setup to prevent this at home, but was getting banned before this.
What did you expect to happen?
Legitimate traffic should not be blocked.
How can we reproduce it (as minimally and precisely as possible)?
Install Immich with multiple albums. Scroll through the albums, go into some albums with many assets, and scrub the timeline.
Anything else we need to know?
