CVE	Summary	Severity	CVSS	EPSS	Priority	Signals
CVE-2026-41948	Path traversal in Dify versions 0 through 1.14.1 allows authenticated tenants to escape their authorized tenant path and reach the Plugin Daemon's internal REST API, including debug interfaces, by smuggling unencoded dot sequences through task identifiers or filename parameters. Because Dify Cloud permits unauthenticated free self-registration, the authentication barrier collapses to trivial account creation, and publicly available exploit code exists; the attacker only needs the victim tenant's UUID to pivot. CVSS 4.0 is rated 9.2 with high confidentiality and integrity impact.	CRITICAL	9.3	0.1%	67	PoC No patch
CVE-2026-41947	Cross-tenant authorization bypass in LangGenius Dify versions through 1.14.1 lets any logged-in editor reroute another tenant's LLM trace traffic - including prompts and model responses - to an attacker-controlled observability provider. Because Dify Cloud permits free self-registration, the authentication barrier is effectively trivial; publicly available exploit code exists and a vendor patch is shipped via PR #35793. The flaw is an instance of CWE-639 (insecure direct object reference) in the trace-configuration endpoints, which accepted an app_id without validating tenant ownership.	CRITICAL	9.3	0.0%	67	PoC
CVE-2026-61461	SQL injection in Dify's MyScale vector store backend (versions before 1.16.0-rc1) lets authenticated attackers execute arbitrary SQL against the underlying ClickHouse database by passing unsanitized search parameters into the search_by_full_text method. Because those parameters are concatenated into the query without escaping or parameterization, an attacker can read, modify, or delete stored vector-store data. Publicly available exploit code exists (VulnCheck advisory and GitHub issue #38281) and a vendor patch is available; there is no confirmation of active in-the-wild exploitation.	HIGH	8.7	0.4%	64	PoC
CVE-2026-41949	Cross-tenant document disclosure in Dify 1.14.1 and prior allows any authenticated user to read up to 3,000 characters of arbitrary uploaded files across all tenants and workspaces by submitting the file's UUID to the /console/api/files/{file_id}/preview endpoint. The flaw is amplified on Dify Cloud, where free self-registration makes account creation trivial, and publicly available exploit code exists via the Huntr disclosure. No CISA KEV listing has been recorded at time of analysis, but the combination of low-friction account access and a documented PoC raises practical exposure considerably.	HIGH	8.2	0.0%	61	PoC
CVE-2026-41950	Dify before version 1.14.0 allows authenticated users to bypass authorization controls and read arbitrary files uploaded by other users within the same tenant by supplying unauthorized file UUIDs in chat-messages API requests. The vulnerability exploits insufficient permission verification on file access endpoints, enabling attackers to circumvent workspace separation and signed URL protections to retrieve sensitive file contents processed through workflows. Publicly available exploit code exists, and a vendor-released patch (version 1.14.0) is available.	MEDIUM	6.0	0.0%	50	PoC
CVE-2026-42138	Unauthenticated users can upload SVG files containing XSS payloads via POST /api/files/upload in Dify prior to version 1.13.1, allowing cross-site scripting attacks against application users. The authenticated endpoint POST /v1/files/upload is similarly vulnerable. This vulnerability enables attackers to execute arbitrary JavaScript in the context of victim browsers, potentially compromising user sessions or stealing sensitive data without requiring any authentication or user interaction.	MEDIUM	6.9	0.1%	35
CVE-2026-18632	Server-side template injection (SSTI) in Dify's Jinja2 Handler (versions ≤1.14.2) allows remote, low-privileged authenticated attackers to inject malicious Jinja2 template expressions through the code execution subsystem, resulting in information disclosure and potential further impact. A public proof-of-concept exploit is available on GitHub, materially lowering the bar for exploitation. The vendor did not respond to responsible disclosure, meaning no patch has been released and no official mitigation guidance exists.	LOW	2.1	0.4%	31	PoC No patch
CVE-2026-85021	Cross-site scripting in Dify 1.13.0 allows unauthenticated remote attackers to inject arbitrary client-side script via the redirect_url argument processed by the router.replace function in the Splash Layout component. Exploitation requires a single user interaction - the victim must follow a crafted link - but no account or prior access to the Dify instance is required. A public proof-of-concept exploit was disclosed on GitHub Gist on or around 2026-07-05; the vendor did not respond to the coordinated disclosure, and no confirmed patch is available at time of analysis.	LOW	2.1	0.4%	31	PoC No patch
CVE-2026-6617	Server-side request forgery (SSRF) in Dify's ApiToolManageService allows authenticated remote attackers to manipulate the URL argument in the get_api_tool_provider_remote_schema function, enabling them to make arbitrary HTTP requests from the server. Affects Dify versions up to 0.6.9. Publicly available exploit code exists, and the vendor has not responded to early disclosure attempts.	LOW	2.1	0.0%	31	PoC No patch
CVE-2026-6618	Server-side request forgery in Dify up to version 1.13.3 allows authenticated remote attackers to manipulate the URL argument in the ApiBasedToolSchemaParser component, enabling arbitrary HTTP requests from the server to internal or external systems. The vulnerability affects the parse_openai_plugin_json_to_tool_bundle function in api/core/tools/utils/parser.py. Publicly available exploit code exists, and the vendor has not responded to early disclosure notification.	LOW	2.1	0.0%	31	PoC No patch
CVE-2026-85022	Cross-site scripting in Dify 1.13.0's WebApp Sign-In component allows remote attackers to inject malicious JavaScript by manipulating the redirect_url parameter consumed by the router.replace() function. The attack requires passive victim interaction with a crafted sign-in URL and low attacker privileges, limiting the immediate impact to integrity modification within the browser context. A public proof-of-concept exploit exists, and the vendor did not respond to coordinated disclosure, leaving no official patch available at time of analysis.	LOW	2.0	0.3%	30	PoC No patch
CVE-2026-6619	Cross-site scripting in Dify's ImagePreview component (web/app/components/base/image-uploader/image-preview.tsx) allows authenticated users to inject malicious scripts via the filename argument in the openInNewTab function, affecting versions up to 1.13.3. The vulnerability requires user interaction (UI:R) and authenticated access (PR:L), limiting impact to low integrity compromise with no confidentiality or availability impact. Publicly available exploit code exists; vendor has not responded to early disclosure.	LOW	2.0	0.0%	30	PoC No patch
CVE-2026-18266	Open redirect in Dify's OAuth flow enables remote attackers to hijack post-authentication redirections, sending users to attacker-controlled sites that can harvest OAuth tokens or credentials. The flaw resides in the AppInitializer component's oauth_redirect_url handling, where the redirect destination is not validated against an allowlist. Exploitation requires user interaction - a target must follow a crafted link - but no authentication is required of the attacker, making phishing-based delivery straightforward. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.	MEDIUM	5.4	0.2%	27	No patch
CVE-2026-34082	Dify prior to version 1.13.1 allows any authenticated user to delete other users' chat histories via the DELETE /console/api/installed-apps/<appId>/conversations/<conversationId> endpoint due to insufficient authorization checks. An authenticated attacker can target any conversation ID to perform unauthorized deletion, resulting in data loss for other users. This vulnerability requires valid Dify authentication but no special privileges, affecting all vulnerable versions via network access.	MEDIUM	5.3	0.0%	27	No patch
