madpsy ka9q_ubersdr before 0.1.58 has a stored cross-site scripting (XSS) vulnerability in the chat message rendering functionality. User-controlled URLs in chat messages were insufficiently neutralized before being converted into HTML links. Quotation characters could break out of the generated href attribute and introduce attacker-controlled HTML attributes, allowing arbitrary JavaScript to execute in the browser of another user when the stored chat message was rendered. No click on the malicious link was required.

Cinnamon's Kotaemon (all versions up to and including v0.12.0) multi-user chat interface contains multiple vulnerabilities due to incorrect authorization and improper access controls. There are four handler methods in `libs/ktem/ktem/pages/chat/control.py` that load a Conversation record by its ID without comparing the requester's `user_id` to the conversation's owner `Conversation.user`. This allows any authenticated user to perform the following actions: 1. Read other user's chat transcripts, RAG retrieval history, AI-generated plots, and chat suggestions. 2. Permanently delete another user's conversation. 3. Rename another user's conversation. 4. Overwrite another user's conversation's chat suggestion list.

Sep 18, 2026Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots: Authorization bypassCVE-2026-89334 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.15.33. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to access the full message transcript, thread metadata, and user data of any chat-room thread without authentication. This is only exploitable when the chat room's only_joined_can_read setting retains its default value of '0'.

Sep 18, 2026Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots: Information Exposure by SpoofingCVE-2026-89093 · WordPress plugins & themes · reported by WordfenceMedium 5.3
The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to Information Exposure by Spoofing in all versions up to, and including, 2.15.33. This is due to the `is_ai_bot_user()` function identifying privileged internal AI bot accounts by performing a prefix check for `'ai-chat-bot-'` against a guest record's stored IP address, which is populated verbatim from the client-controlled `X-Real-IP` request header during unauthenticated guest registration. This makes it possible for unauthenticated attackers to register a guest identity that the plugin treats as its own internal AI bot, bypassing the per-room role allowlist, draft-status check, and join filters — which are all short-circuited by the bot check in `user_can_join()` and `user_can_read()` — to join administrator-restricted chat rooms, post messages into them, and read the private message history of other users.

ArcadeDB before 26.9.1 contains an access control bypass vulnerability in the query_database tool exposed through the AI chat endpoints. The tool executes queries without binding the authenticated principal to DatabaseContext, causing per-type and per-bucket ACL checks to silently no-op and allowing authenticated users to read data they are explicitly denied at the per-type level. Attackers can prompt the AI assistant to execute queries against restricted types or buckets to retrieve sensitive data that would be rejected through normal query endpoints.

The Foxtool All-in-One: Contact chat button, Custom login, Media optimize images plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.5.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify arbitrary subkeys of the foxtool_settings option, including enabling site-wide SVG uploads by toggling the media-up3 key, which can facilitate stored cross-site scripting via malicious SVG files.

The Floating Chat Widget: Contact Chat Icons, Telegram Chat, Line Messenger, WeChat, Email, SMS, Call Button – Chaty plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 3.5.9 due to insufficient input sanitization and output escaping.

WordPress's server-side HTML encoding of the 's' search parameter in the <title> element is bypassed because the browser DOM API decodes HTML entities when jQuery's .text() method reads document.title, returning literal special characters that are then embedded unescaped into the constructed HTML attribute value.

The Sticky Chat Widget plugin for WordPress is vulnerable to SQL Injection via the 'scw_form_fields' parameter array keys of the 'scw_save_form_data' AJAX action in versions up to, and including, 1.4.2. This is due to the save_form_data() function passing attacker-controlled POST array keys unsanitized to $wpdb->insert(), which wraps column identifiers in backticks without escaping them, allowing a backtick in an attacker-supplied key to break out of the column-identifier list into raw SQL; additionally, the use of filter_input() bypasses WordPress's wp_magic_quotes() protection, and the widget_id validation loop is skipped entirely when no valid widget_id is supplied, leaving $isValid at 1. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. In 1.16.1 and earlier, the manager role can store meta_page_title or meta_page_favicon through /api/admin/system-preferences, and MetaGenerator inserts those values into production homepage HTML without escaping attribute values or text content. The values pass unchanged through server/models/systemSettings.js and reach MetaGenerator.generate() in server/index.js. #assembleMeta() in server/utils/boot/MetaGenerator.js concatenates the stored values into HTML. When an administrator visits the homepage /, injected JavaScript can read the administrator JWT and use it to create API keys, access or modify workspace and chat data, delete users, and perform other administrator actions. server/endpoints/admin.js accepts the manager-controlled settings before server/models/systemSettings.js returns them unchanged.

In DocsGPT 0.15.0 and below, the application provides a custom prompt feature that allows users to define prompt content used during chatbot interactions. This functionality renders user-supplied prompt data using Jinja templates without input sanitization or sandboxing. An unauthenticated attacker can inject malicious template expressions, leading to a server-side template injection (SSTI) vulnerability that can be exploited to achieve full remote code execution (RCE).

Sep 4, 2026smol-toml is a small, fast, and correct TOML parser and serializer.CVE-2026-85730 · Other software · squirrelchat · reported by GitHubHigh 8.2
smol-toml is a small, fast, and correct TOML parser and serializer. Prior to 1.7.1, parse() can enter an infinite loop when a value inside an array or inline table is followed by a comment with no trailing newline. In src/util.ts, skipUntil() calls indexOfNewline(), receives -1 at the end of input, and resets the cursor to the beginning of the string instead of leaving the structure scan. The parser then hangs indefinitely and can consume a service's processing capacity when an application parses attacker-controlled TOML. This issue is fixed in version 1.7.1.

Chatbot UI contains an authorization bypass vulnerability in the retrieval endpoint that allows authenticated attackers to access private file content belonging to other users by supplying arbitrary file UUIDs. The endpoint uses a service-role Supabase client that bypasses row-level security and fails to validate file ownership, enabling attackers to retrieve indexed content chunks from victim files through crafted POST requests.

aider (aider-chat) automatically loads a .aider.conf.yml configuration file from the root of the git repository it is launched in. A crafted repository can set test-cmd (executed at startup) or lint-cmd (executed on the first file edit), which aider runs through a shell (subprocess with shell=True) without any user confirmation, LLM interaction, or API key. Consequently, a user who clones and runs aider inside an attacker-supplied repository achieves arbitrary command execution on their machine. The behavior is long-standing and was confirmed on 0.86.3.dev (current main).

Sep 4, 2026LobeChat (LobeHub) 2.2.1 does not properly verify inbound chat-platform webhook signatures in the QQ and Feishu adapters.CVE-2026-85621 · Other software · lobehub · reported by VulnCheckMedium 6.9
LobeChat (LobeHub) 2.2.1 does not properly verify inbound chat-platform webhook signatures in the QQ and Feishu adapters. The webhook route (/api/agent/webhooks/:platform) is unauthenticated by design and delegates verification to each adapter; the QQ adapter performs no Ed25519 signature verification on dispatched message events, and the Feishu adapter only performs an optional static-token comparison that is skipped when no token is configured (the default) and is not a body signature. An unauthenticated attacker who knows the public webhook URL can POST forged inbound messages with an attacker-chosen sender identity and arbitrary text, causing the bot owner's agent to process attacker-controlled input and treat the attacker as a trusted platform sender.

Sep 1, 2026BetterDocs – AI Documentation, Knowledge Base, Docs, Wikis, FAQ with Chatbot: Stored Cross-Site ScriptingCVE-2026-75980 · WordPress plugins & themes · reported by WordfenceMedium 6.4
The BetterDocs – AI Documentation, Knowledge Base, Docs, Wikis, FAQ with Chatbot plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Heading 'id' Attribute in Post Content in all versions up to, and including, 4.8.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit survives wp_kses_post because entity-encoded quotes in a heading id attribute are treated as a single legitimate attribute value at save time; the dangerous payload only materialises after process_content_for_toc() calls html_entity_decode() on the stored content and the broken id is extracted by a lazy regex before being echoed unescaped into the Table of Contents output.

The Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System plugin for WordPress is vulnerable to Authentication Bypass leading to Administrator Account Takeover in all versions up to, and including, 1.4.52 via the `guest_ticket_login()` function and its `p` parameter. This is due to the site-wide AES-256-CBC encryption key being derived from only three two-digit `wp_rand(10, 99)` values and a Unix timestamp via `md5()` — yielding approximately 19.5 bits of entropy — combined with a deterministic IV derived from the password, no authentication tag on the ciphertext, and no capability check, nonce, or session validation on the publicly reachable `/sgnix/?p=<token>` endpoint. This makes it possible for authenticated attackers, with subscriber-level access and above, who can obtain a single legitimate guest ticket token as a known-plaintext oracle and bound the plugin activation timestamp, to exhaust the ~729,000-candidate keyspace entirely offline, recover the site-wide encryption key, and forge a self-consistent `{ticket_id, ticket_user}` token targeting any administrator-owned ticket.

Generation of Error Message Containing Sensitive Information vulnerability in ash-project ash_ai discloses internal error text to chat users. In AshAi.ToolLoop and AshAi.Tools, an exception raised while executing a tool was serialized verbatim with Exception.message/1 into the tool-result content. That content is appended to the conversation, emitted as a {:tool_result, ...} stream event, and sent back to the model, which typically relays it to the user. No filtering happened first, so anything raised inside a tool callback or lifecycle hook (database constraint messages, adapter errors, query fragments, policy or validation internals) was echoed as-is. A chat user who can steer tool arguments into a raising code path receives the raw internal text. The fix routes raised tool errors through the same safe formatter used for other tool errors. This issue affects ash_ai: from 0.6.0 before 1.0.0.
