## Executive Summary (TL;DR)
Open WebUI v0.9.6. Source highlight: 📦 **Official knowledge base sync tool.** A new companion tool from Open WebUI, oikb, keeps a knowledge base in sync with a local directory, GitHub repo, S3 bucket, Confluence space, or any of more than 40 other sources, uploading only new and changed files using the incremental sync support added in

## Breaking Changes & Deprecations
- - 🔣 **Collection name validation.** Vector collection names are now rejected unless they contain only safe characters, preventing malformed names from reaching the vector store or breaking out of a database query expression. [#24982](https://github.com/open-webui/open-webui/pull/24982)
- - 🧼 **Model profile image script injection.** Model profile images are now validated on save and only served inline when they are a known-safe image type, preventing a crafted SVG profile image from running scripts in other users' browsers, while existing legacy images that fail validation are cleared gracefully instead of breaking the model list. [#25060](https://github.com/open-webui/open-webui/pull/25060), [#25173](https://github.com/open-webui/open-webui/pull/25173)
- - 🧩 **Chat recovery from corrupted history.** Chats whose internal message graph was left in a malformed state by a failed regeneration now open and load correctly, with missing roles, parent references, and current-message pointers reconstructed automatically instead of breaking the chat. [#24424](https://github.com/open-webui/open-webui/issues/24424), [#24157](https://github.com/open-webui/open-webui/issues/24157), [#20474](https://github.com/open-webui/open-webui/issues/20474), [#24799](https://github.com/open-webui/open-webui/pull/24799), [Commit](https://github.com/open-webui/open-webui/c
- - 🩹 **Graceful handling of in-chat task failures.** When web search query generation, image prompt generation, or a tool call fails or references a missing tool, the chat now falls back or surfaces a clear error instead of breaking partway through the response. [#25038](https://github.com/open-webui/open-webui/issues/25038), [#25144](https://github.com/open-webui/open-webui/issues/25144), [Commit](https://github.com/open-webui/open-webui/commit/b64fd988f02b8a4295193892b24b00bdf635a4dc)

## New Features
- 📦 **Official knowledge base sync tool.** A new companion tool from Open WebUI, oikb, keeps a knowledge base in sync with a local directory, GitHub repo, S3 bucket, Confluence space, or any of more than 40 other sources, uploading only new and changed files using the incremental sync support added in this release. oikb
- 📂 **Smart directory sync for knowledge bases.** Local directories can now be synced into a knowledge base in one action: file checksums are compared against what's already stored, and only added or modified files are uploaded while removed files and orphaned subdirectories are cleaned up, with the directory structure mirrored automatically and per-file progress shown throughout. #19190, #19394, Commit, Commit, Commit, Commit, Commit, Commit
- 🗂️ **Knowledge base folders.** Files inside a knowledge base can now be organized into nested folders, with breadcrumb navigation that makes it much easier to manage and find content in large collections. Commit, Commit, Commit, Commit, Commit, Commit
- 🧰 **Filesystem tool for knowledge bases.** A new built-in tool, enabled via the "ENABLE_KB_EXEC" environment variable, lets AI models browse and search knowledge base contents using familiar filesystem commands such as 'ls', 'cat', 'grep', 'find', 'head', 'tail', and 'sed', including pipes between them.

- ✏️ **File renaming in knowledge bases.** Files inside a knowledge base can now be renamed directly from the workspace, with the new name reflected wherever the file is referenced. Commit
- 😀 **Emoji picker in message input.** A new emoji button in the rich text formatting toolbar lets you browse and insert emojis directly into your messages. #24704

## Bug Fixes
- 📄 **Configurable knowledge base file page size.** Administrators can now request a larger page size when listing a knowledge base's files through the API, reducing the number of requests needed to retrieve large collections instead of paging through fixed increments of 30. #25148, Commit
- 🛡️ **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
- 🛡️ **Tool server permission enforcement.** The per-user permission for inline tool servers is now enforced on chat-completion requests, so users without that permission can no longer bypass the admin setting by supplying tool servers directly in their requests. Commit
- 🔒 **Knowledge base access check in search tool.** The built-in knowledge search tool now verifies that the caller can access a knowledge base before searching it by id, preventing users from reading the contents of knowledge bases they have not been granted access to. #25113
- 🗄️ **Cross-user access to retrieval collections.** Resolving the documents used for retrieval now verifies the caller's access to each referenced file and rejects client-supplied collection names, preventing a crafted request from pulling another user's files or vector collections into its context.

- 🔣 **Collection name validation.** Vector collection names are now rejected unless they contain only safe characters, preventing malformed names from reaching the vector store or breaking out of a database query expression. #24982
