 ### Fixed
 
-- 🔒 **Public sharing permission bypass fix.** Users with write access to knowledge bases, tools, skills, prompts, and models could previously see and use the "Public" sharing option regardless of their actual sharing permissions, and direct API calls could bypass frontend restrictions entirely; both frontend and backend now properly enforce sharing.public_* permissions, silently stripping public grants when users lack the corresponding permission. [#21356](https://github.com/open-webui/open-webui/issues/21356), [#21358](https://github.com/open-webui/open-webui/pull/21358)

[#21356](https://github.com/open-webui/open-webui/issues/21356), [#21358](https://github.com/open-webui/open-webui/pull/21358)
 - 🐘 **PostgreSQL analytics query fix.** The get_chat_ids_by_model_id function now works correctly with PostgreSQL by using GROUP BY with aggregate ordering instead of DISTINCT with non-aggregate ORDER BY, which PostgreSQL does not support. [Commit](https://github.com/open-webui/open-webui/commit/7bda6bf767d5d5c4dc1111465096a88e10b5030e)
 - 🐘 **Skills PostgreSQL compatibility fix.** Skills now work correctly with PostgreSQL by using SQLAlchemy's native JSON column type instead of the custom JSONField, which caused compatibility issues. [Commit](https://github.com/open-webui/open-webui/commit/b4c3f54f9648c4232a0fd6557703ffa66fcf4caa)
 - 🗑️ **Chat message deletion cascade fix.** Deleting chats now properly removes associated chat messages from the database, preventing orphaned message records from accumulating when chats or shared chats are deleted. [#21362](https://github.com/open-webui/open-webui/pull/21362)
