CVE Vulnerability Catalog

n8n versions before 1.123.73, 2.35.4, and 2.36.2 contain an expression sandbox escape in the $fromAI handler. An attacker with workflow-build privilege can walk the prototype chain to the Function constructor and execute arbitrary code in the main n8n process, leading to remote code execution.

n8n versions before 1.123.73, 2.35.4, and 2.36.2 contain a remote code execution vulnerability in the Git node. The node resets a fixed list of command-bearing configuration keys before each operation, but that list does not cover the content-filter and merge-driver key families. A repository with local configuration setting one of those keys together with a matching attribute pattern causes git to execute the configured command during an ordinary Add, Commit, Checkout, or Pull operation, running as the n8n process user.

n8n before 2.35.4 and 2.36.x before 2.36.2 contain a query injection vulnerability in Elasticsearch Document Get All and Google Cloud Firestore Document Query operations. Expression values are interpolated directly into the JSON query, allowing modification and full-collection reads.

n8n before 2.35.4 and 2.36.x before 2.36.2 does not validate credential references in the inline workflow JSON of nodes that execute an inline sub-workflow (e.g., the Workflow Tool node). A shared-workflow editor, or any user creating/updating a workflow via the REST API, Public API, or MCP, can persist a node referencing a credential they do not own. When the workflow is later executed under an identity that holds the credential, the inline sub-workflow resolves the secret and can send it to an attacker-controlled endpoint, resulting in credential exfiltration.

n8n versions before 2.36.2 contain an expression sandbox bypass vulnerability where free identifiers in spread, computed-key, switch-case, or class-extension positions resolve against process globals. Authenticated users with workflow-edit permission can mutate host objects through expression evaluation, with changes persisting process-wide until restart.

WWBN AVideo through commit c91b5975d contains a server-side request forgery vulnerability in the set_api_userImages API endpoint that fails to validate profileImg and backgroundImg URLs before fetching them. Authenticated API clients can supply internal URLs to fetch cloud metadata or internal services, with responses written to publicly accessible web paths for retrieval.

AVideo through commit c91b5975d contains a server-side request forgery vulnerability in the EPG parser that allows authenticated uploaders to fetch arbitrary internal URLs. An attacker can supply an internal URL via the epg_link parameter, which is only syntax-validated and later fetched server-side without SSRF protection.

AVideo through commit c91b5975d contains a cross-site request forgery vulnerability in plugin/Live/saveLive.php that lacks forbidIfNotPost and forbidIfInvalidToken protections. Attackers can craft malicious image tags to overwrite authenticated streamers' RTMP keys, passwords, and titles, hijacking live broadcasts.

AVideo through commit c91b5975d contains a cross-site request forgery vulnerability in removePoster.php that lacks forbidIfNotPost or forbidIfInvalidToken checks. Attackers can craft malicious image tags to delete authenticated victims' live poster and thumbnail files via GET requests.

AVideo through commit c91b5975d contains a cross-site request forgery and path traversal vulnerability in stopLive.php that allows attackers to delete directories by exploiting missing token validation and unsanitized key parameter concatenation. Attackers can craft an image tag with a traversal payload like key=../../videos to trigger recursive deletion of the videos directory when an admin visits a malicious page.

AVideo through commit c91b5975d contains a reflected cross-site scripting vulnerability in userLogin.php where the cancelUri parameter is echoed in an href attribute after isSafeRedirectURL checks protocol only, not HTML characters. Unauthenticated attackers can inject event handlers via relative URLs with embedded quotes to execute arbitrary JavaScript.

AVideo through commit c91b5975d contains a reflected cross-site scripting vulnerability in videoEmbeded.php that echoes the link parameter inside an HTML comment with zero escaping. Attackers can close the comment with --> and inject arbitrary JavaScript that executes when victims visit the crafted embed URL.

WWBN AVideo contains a broken access control vulnerability in the unauthenticated feed/index.php endpoint that disables per-video visibility checks when a program_id parameter is supplied. Attackers can enumerate playlist identifiers and retrieve unlisted and group-restricted videos by requesting the RSS feed with any visible playlist id, including empty playlists that return the entire site's hidden video catalogue.

WWBN AVideo fails to properly validate access controls on the public channel page, allowing unauthenticated visitors to view unlisted and group-restricted videos through hardcoded visibility flags and an undefined property. Attackers can access the channel endpoint to retrieve sensitive video content that should be hidden, including full URLs to unlisted videos and thumbnails of member-only content, regardless of the operator's hidePrivateVideos setting.

WWBN AVideo contains a SQL injection vulnerability in the sort column parameter of the get.json.php endpoint with APIName=channels that allows unauthenticated attackers to order results by arbitrary database columns including users.password and users.recoverPass. Attackers can exploit this ordering oracle to infer password hash values and recovery tokens, and trigger SQL errors that disclose the full query statement and database schema.

WWBN AVideo contains an authentication failure vulnerability where the video_id_hash credential is a non-expiring, non-revocable bearer token that grants full administrator session access to the video owner's account. Attackers who obtain a video_id_hash can replay it indefinitely to authenticate as the video owner with full privileges, and the credential remains valid even after the owner changes their password.

A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.

@fastify/http-proxy versions before 11.6.2 do not validate proxied HTTP request paths for backslash based dot-segments before forwarding them to the configured upstream. The plain HTTP request handler skips the destination validation that the WebSocket path performs, and the underlying reply-from library only rejects forward-slash traversal, so a request containing backslash dot-segments can escape the boundary set by the prefix and rewritePrefix options. An unauthenticated network attacker can use this to reach upstream paths that were meant to stay hidden behind the proxy, resulting in disclosure of internal endpoints. This is a path traversal issue (CWE-22). Users should upgrade to @fastify/http-proxy 11.6.2 or later.

A vulnerability was found in NousResearch hermes-agent 0.18.0. This vulnerability affects the function resourceBufferFromUrl of the file apps/desktop/electron/main.ts of the component Electron Main Process. Performing a manipulation results in allocation of resources. The attack may be initiated remotely. copyImageFromUrl() entry point no longer reachable on current main. That function did exist at v2026.8.3 but was removed by v2026.8.19. The modern copy-image path is Electron-native event.sender.copyImageAt().

A vulnerability has been found in NousResearch hermes-agent 0.18.0. This affects the function fetchLinkTitle of the file apps/desktop/src/app/artifacts/index.tsx of the component Link Title Fetch. Such manipulation of the argument url leads to server-side request forgery. The attack can be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.
