Trivy legacy-format reports have no "Class" field, so the parser set unsaved_tags entries to None (e.g. ['debian', None]). clean_tags then crashed the whole import with TypeError in TAG_PATTERN.sub, after parsing had already succeeded (regression from DefectDojo#14111 in 2.55.0). - clean_tags: drop None entries instead of crashing (defends every parser) - trivy parser: filter falsy values at all four unsaved_tags sites - regression tests: clean_tags None handling; legacy fixture tags contain no None Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Description
Fixes #15005. Importing a legacy-format Trivy report that has no
Classfield crashes the import pipeline after parsing succeeds, withTypeError: expected string or bytes-like object, got 'NoneType'inclean_tags. The parser setunsaved_tagsentries toNone(e.g.['debian', None]);clean_tagsthen ranTAG_PATTERN.sub("_", None)and raised, aborting the whole import.Two-part fix:
dojo/validators.py—clean_tagsnow dropsNoneentries instead of crashing. This defends the pipeline against any parser that emits aNonetag, not just Trivy.dojo/tools/trivy/parser.py— all fourunsaved_tagsassignments now filter out falsy values at the source, so legacy reports keep their real tag (debian) and simply omit the missingClass.Test results
Extended the suite (both run green):
unittests/test_validators.py(new) —clean_tagswithNoneentries, mixed, all-None, plus existing string/list/empty/invalid-type behavior.unittests/tools/test_trivy_parser.py— asserts the legacy fixture's findings contain noNonetags.Verified end-to-end on a live 2.59.0 instance: before the fix the import returns HTTP 500 (and leaks 1 partial finding); after, HTTP 201 with all 93 findings (0 Critical / 18 High / 9 Medium / 65 Low / 1 Info), each tagged
debian.Documentation
None needed — bug fix, no behavior/config/model surface change.
