Stacked on #67926 — applies the same pre-import class-path validation to the `AIRFLOW_EXC_SER` / `BASE_EXC_SER` exception branches that #67926 adds for `BASE_TRIGGER`, reusing the shared `_safe_import_for_deserialize` helper. Review the top commit; the first commit belongs to #67926 and drops out once it merges. Exception classes are now resolved through the trusted-namespace allowlist (validated before `import_string`), then verified as `BaseException` subclasses. Builtins stay allowed for standard exceptions; the subclass check rejects non-exception builtins. ### Tests - [X] `AIRFLOW_EXC_SER` path outside trusted namespaces rejected before import - [X] `BASE_EXC_SER` non-exception builtin (e.g. `eval`) rejected - [X] genuine builtin exception still round-trips ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Opus 4.8 (1M context) Generated-by: Claude Opus 4.8 (1M context) following the guidelines at https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions -- This is an automated message from the Apache Git Service.
