CVE Vulnerability Catalog

Open WebUI versions from 0.6.33 before 0.11.4 contain a cross-site scripting vulnerability that allows authenticated users to execute script in victims' sessions by storing javascript: URLs in citation embed_url fields. Attackers can share a crafted chat whose citation, when clicked, is passed to window.open, letting them steal localStorage.token and act as the victim.

Open WebUI versions from 0.11.1 before 0.11.4 contain a stored cross-site scripting vulnerability in DocxPreview.svelte that allows authenticated users to execute script by uploading crafted DOCX attachments. Attackers can embed an OOXML altChunk HTML part or script-scheme hyperlink to steal a previewing administrator's session token from local storage and take over the instance.

Open WebUI from 0.8.8 before 0.11.4 contains an improper authorization vulnerability that allows deactivated users to keep executing terminal commands through an already open terminal WebSocket. Because the terminal proxy route in terminals.py checks access only on the first message, deactivated users can keep running commands and reading or writing files on the terminal server.

Open WebUI before 0.11.4 contains a stored cross-site scripting vulnerability in MarkdownInlineTokens.svelte, which renders markdown link URLs into anchor hrefs without validating their scheme. Authenticated users can embed javascript: links in shared chats that, when clicked by a victim, steal the victim's JWT from local storage, including admins' tokens.

Open WebUI from 0.9.6 before 0.11.4 contains an authorization flaw where the knowledge base file listing does not verify that a supplied directory_id belongs to the requested knowledge base. Users with read access to any knowledge base can supply a retained foreign directory UUID to GET /api/v1/knowledge/{id}/files. The returned breadcrumbs expose folder names, owner user ids and knowledge base ids of that directory and all its ancestors.

Open WebUI from 0.7.0 before 0.11.4 contains a cross-origin message handling vulnerability in SyncStatsModal that allows any website to steal a signed-in user's session token by posting unvalidated verify:chat messages. Attackers can supply a path-traversal chat id redirecting the authenticated stats export request to the auths endpoint, receiving the victim's JWT for full API access.

Open WebUI from 0.6.0 before 0.11.4 contains an improper access control vulnerability in has_access_to_file that lets former knowledge base collaborators keep file access via stale cached knowledge base references. Attackers with read or write grants can download removed files through the file content endpoint or delete them, including from the owner's private knowledge bases.

Open WebUI from 0.11.0 before 0.11.4 contains an improper authorization vulnerability in the chat fork handler, which places forked chats in the source chat's folder without checking folder write access. Shared folder members downgraded to read-only can call POST /api/v1/chats/{id}/fork on chats they created there while they had write access, inserting attacker-controlled chats visible to the folder owner and members.

Open WebUI from 0.11.1 before 0.11.4 contains an authorization bypass in the OAuth token exchange endpoint, which reads role claims only from the provider's userinfo response and keeps the user's existing role when no roles claim is found, ignoring roles sent only in the ID token. Users with a linked account whose identity provider role no longer satisfies the OAuth role policy can send a valid provider access token to POST /api/v1/auths/oauth/{provider}/token/exchange to obtain a session retaining their previous role.

ImageMagick before 6.9.13-57 and 7.1.2-32 contains a type confusion flaw in the INFO, JSON, and YAML encoders when writing compressed images, causing an unexpected pointer type. An attacker can trigger a process crash via SIGABRT or SIGSEGV, leading to denial of service.

ImageMagick 7.1.0-21 before 7.1.2-32 contains a heap buffer over-read in its handling of the -fx option, where a certain -fx operation reads beyond the bounds of an allocated heap buffer in specific situations. Attackers who can get a crafted -fx expression processed can read out-of-bounds heap memory, potentially disclosing limited memory contents.

ImageMagick 7.1.0-20 before 7.1.2-32 has a use-after-free vulnerability in the -fx option when memory allocation fails during a specific operation. Attackers supplying crafted -fx expressions under memory pressure can trigger freed memory access, causing crashes or memory corruption.

ImageMagick before 6.9.13-57 and 7.1.2-32 lacks proper synchronization when accessing the security policy, leading to a race condition between concurrent reads and writes by multiple threads, causing a heap buffer over-write. An attacker inducing concurrent security policy access can crash the application, causing denial of service.

ImageMagick before 6.9.13-57 and 7.1.2-32 has a memory leak in the wavelet-denoise operation, which fails to release allocated memory when a required resource cannot be acquired. Attackers can repeatedly trigger this operation under resource-constrained conditions to leak memory and degrade service availability.

ImageMagick before 7.1.2-32 has a policy bypass vulnerability in the -script operation due to missing checks on file descriptor handling. Attackers can use -script to close file descriptors not opened by the current operation, circumventing security policies.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an incomplete cleanup flaw in the JNG decoder that fails to remove temporary files when processing crafted input. Attackers can submit crafted JNG files for processing to repeatedly leak temporary files, consuming disk space and degrading availability.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a code injection vulnerability in the MVG decoder when a PostScript renderer is used. Attackers can supply a crafted MVG file that, when decoded, injects code into the PostScript rendering path.

ImageMagick before 7.1.2-32 has a time-of-check time-of-use symlink race vulnerability that allows attackers to bypass the path security policy when executing a magick script. Attackers can swap a checked path with a symlink during script execution to read files blocked by the policy.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an information disclosure vulnerability in the PostScript decoder, which allocates a buffer one byte longer than the data it decoded. Attackers can supply a crafted PostScript file to expose a single uninitialized byte of memory contents.

ImageMagick 7.1.1-31 before 7.1.2-32 has a NULL pointer dereference in the PostScript decoder triggered when a policy limit is reached. Attackers can supply a crafted PostScript file to crash the application, causing denial of service.
