Sep 23, 2026Cinnamon's Kotaemon (all versions up to and including v0.12.0) multi-user chat interface contains multiple vulnerabilities due to incorrect authorization and imCVE-2026-86867 · Other software · Cinnamon AI · reported by cret@cert.orgMedium 6.5
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.

kotaemon through 0.12.0 contains an insecure deserialization vulnerability in the check_connection endpoint that allows unauthenticated attackers to instantiate arbitrary Python classes by supplying crafted YAML/JSON input with a __type__ field. Attackers can exploit this to override the __type__ field with subprocess.check_output and arbitrary arguments, achieving remote code execution with application process privileges.

Nov 24, 2025An issue was discovered in Cinnamon kotaemon 0.11.0.CVE-2025-63914 · Other software · Cinnamon · reported by MITREMedium 6.5
An issue was discovered in Cinnamon kotaemon 0.11.0. The _may_extract_zip function in the \libs\ktem\ktem\index\file\ui.py file does not check the contents of uploaded ZIP files. Although the contents are extracted into a temporary folder that is cleared before each extraction, successfully uploading a ZIP bomb could still cause the server to consume excessive resources during decompression. Moreover, if no further files are uploaded afterward, the extracted data could occupy disk space and potentially render the system unavailable. Anyone with permission to upload files can carry out this attack.

Jul 2, 2025kotaemon is an open-source RAG-based tool for document comprehension.CVE-2025-53358 · Other software · Cinnamon · reported by GitHubMedium 6.5
kotaemon is an open-source RAG-based tool for document comprehension. From versions 0.10.6 and prior, in libs/ktem/ktem/index/file/ui.py, the index_fn method accepts both URLs and local file paths without validation. The pipeline streams these paths directly and stores them, enabling attackers to traverse directories (e.g. ../../../../../.env) and exfiltrate sensitive files. This issue has been patched via commit 37cdc28, in version 0.10.7 which has not been made public at time of publication.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
