CVE-2026-55611
AnythingLLM: embed-parsed-file cleanup deletes any parsed file by ID without ownership scoping (cross-tenant IDOR deletion)
Description
AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. From 1.11.1 until 1.14.1, userId/workspaceId scoping to the parsed-files read/delete paths was added. However, the POST /api/workspace/:slug/embed-parsed-file/:fileId flow still deletes the target file by primary key only, with no ownership check, inside two finally{} blocks that run even when the ownership-checked read fails. As a result a manager or admin (multi-user mode) can delete any other user's parsed file in any workspace — including workspaces they are not a member of — by enumerating integer fileIds. The server even returns "File not found" while still deleting the file. This vulnerability is fixed in 1.14.1.
