+## Fix UI overwriting service field from parsers
+
+The web form in the UI by default sends an empty string, which ended up overwriting the service value provided by parsers.
+
+Only a few parsers do this, so the impact of this fix is low:
+
+- Trivy Scan
+- Trivy Operator Scan
+- Hydra Scan
+- JFrog Xray API Summary Artifact Scan
+- StackHawk HawkScan
+
+See [PR 13517](https://github.com/DefectDojo/django-DefectDojo/pull/13517) for more details.
+
 ## Deduplication fix of `UNIQUE_ID_OR_HASH_CODE`
 A bug was fixed in the `UNIQUE_ID_OR_HASH_CODE` algorithm where it stopped processing candidate findings with equal `unique_id_from_tool` or `hash_code` value.
 Strictly speaking this is not a breaking change, but we wanted to make you aware that you can see more (better) more deduplicatation for parsers using this algorithm.
