 ### Fixed
 
 - 🛡️ **Security Advisory**: This release includes security and access-control fixes. We recommend updating production deployments at your earliest convenience. Not all security fixes in this version may be enumerated in the fixed section. Some may be withheld for a short time to give administrators time to upgrade. [Advisories](https://github.com/open-webui/open-webui/security)
+- 💣 **Documents that unpack far beyond their size.** A Word, Excel, PowerPoint, OpenDocument or EPUB file that expands to far more than it stores is now rejected before it is read, where one could previously be used to exhaust a server's memory. [Commit](https://github.com/open-webui/open-webui/commit/2a0274a0a039dbe0a1ad4d24003b085aae7b896b)
 - 🗝️ **Changing a password now ends other sessions.** Changing your password, or an administrator resetting it for you, now stops every device that was already signed in, where they had stayed signed in on the old password until their session expired on its own, up to four weeks by default; the device making the change is signed out too and asked to sign in again, and this requires Redis, without which nothing can be revoked and a warning is now logged saying so. [#28725](https://github.com/open-webui/open-webui/pull/28725), [#28647](https://github.com/open-webui/open-webui/discussions/28647)
 - 🧬 **Workspace models shadowing a real one.** Someone without administrator rights can no longer create, import, or edit a workspace model so that it takes over the identity of a model served by a connected provider, where doing so would have changed what everyone else got when they picked that model. [Commit](https://github.com/open-webui/open-webui/commit/ea55d38793014a4e3cd5a4046816fe22e69e9739)
 - 🌳 **Folders disappearing when moved into themselves.** Moving a folder inside one of its own subfolders is now refused, where it was accepted and made that folder and everything in it vanish from the sidebar with no way to bring it back, while leaving the server walking the loop endlessly and querying the database as it went, which could exhaust a worker and its memory; any folder already in that state is returned to the top level.

 - 👤 **Fallback profile pictures.** A profile picture that fails to load, such as one belonging to a deleted account, now falls back to the default avatar instead of showing clipped placeholder text beside the message. [#28270](https://github.com/open-webui/open-webui/pull/28270), [#28269](https://github.com/open-webui/open-webui/issues/28269)
 - ⏱️ **Unanswered prompts in tools.** On deployments that set "WEBSOCKET_EVENT_CALLER_TIMEOUT", a question a tool asks you that goes unanswered now reports a timeout rather than an empty reply, and waiting too long no longer risks disconnecting a tab that is still open. [#28311](https://github.com/open-webui/open-webui/pull/28311)
 - 👪 **Group member counts updating.** Adding or removing someone from a group in the admin panel now updates that group's member count straight away, where it stayed at the old number until the page was reloaded. [Commit](https://github.com/open-webui/open-webui/commit/18bf0ade7b35fb25ff7920ad3713624d93f04401)
+- 🕳️ **Blank messages left in a conversation.** Streamed events that never fill in an item no longer leave an empty assistant message saved in the conversation and sent back to the model on every later turn.
