|---|---|---|---|---|
| hash | path | /avatar/:hash | Description of vulnerability: uncached /avatar/:hash requests spawn goroutines to refresh Gravatar images; if the refresh waits longer than 3 seconds in a 10-slot worker queue, the handler times out and stops listening, causing the goroutine to block on an unbuffered channel. With sustained traffic and random hashes, this leads to growing goroutine counts, memory exhaustion, and potential Grafana crashes. | CWE-400, CWE-703, CWE-772 |
