CVE	Summary	Severity	CVSS	EPSS	Priority	Signals
CVE-2026-42208	SQL injection in LiteLLM proxy server versions 1.81.16 through 1.83.6 allows unauthenticated remote attackers to read and modify database contents, gaining unauthorized access to managed LLM API credentials. The vulnerability is exploitable via crafted Authorization headers sent to any LLM API route (e.g., POST /chat/completions), triggering the injection through the proxy's error-handling path. Vendor-released patch available in version 1.83.7. No active exploitation confirmed (not in CISA KEV), but the attack vector is simple (CVSS 4.0: AV:N/AC:L/PR:N) and SQL injection POCs are widely known. Discovered by Tencent YunDing Security Lab.	CRITICAL	9.3	0.1%	117	KEV PoC
CVE-2026-59822	Authentication bypass in LiteLLM (BerriAI) proxy/AI Gateway before 1.84.0 lets a remote unauthenticated attacker reach MCP tooling by sending a fabricated Authorization header. The malformed header forces the MCP Streamable HTTP endpoint down an OAuth2 passthrough fallback that substitutes a failed key validation with an empty UserAPIKeyAuth() object, effectively treating the caller as authorized without any valid LiteLLM key. The CVSS 4.0 score of 8.8 reflects network-reachable, no-privilege access with high confidentiality impact; no public exploit identified at time of analysis and it is not listed in CISA KEV.	HIGH	8.8	0.3%	114	KEV PoC
CVE-2026-42271	Remote command execution in LiteLLM proxy server versions 1.74.2 through 1.83.6 allows any authenticated user to execute arbitrary commands on the host system. Two MCP (Model Context Protocol) test endpoints accept stdio transport configurations including command, args, and env fields, then spawn the supplied command as a subprocess with proxy process privileges. Authentication with any valid API key, including low-privilege internal-user keys, bypasses intended PROXY_ADMIN role restrictions. Patch available in version 1.83.7. No CISA KEV listing or public exploit code identified at time of analysis, though EPSS scoring is not provided in available data.	HIGH	8.7	0.0%	114	KEV PoC
CVE-2026-40217	Remote code execution in BerriAI LiteLLM (all versions through 2026-04-08) enables authenticated attackers to execute arbitrary code by exploiting bytecode rewriting functionality at the /guardrails/test_custom_code endpoint. The vulnerability requires low-privilege authentication (PR:L) but permits complete system compromise with high impact to confidentiality, integrity, and availability. No public exploit identified at time of analysis.	HIGH	8.8	0.2%	64	PoC
CVE-2026-12773	Authentication bypass in BerriAI LiteLLM versions 1.59.0 through 1.59.8 allows unauthenticated remote attackers to circumvent the UserAPIKeyAuth function within the experimental MCP Proxy server component, gaining unauthorized access to protected LLM proxy functionality without valid credentials. A public proof-of-concept exploit is confirmed available via GitHub gist (YLChen-007), materially lowering the bar for exploitation. No CISA KEV listing is present at time of analysis, but the network-accessible, zero-authentication attack surface combined with an available PoC warrants urgent remediation prioritization for any deployment with the MCP server component exposed.	MEDIUM	5.5	0.4%	48	PoC
CVE-2026-12795	Missing authentication in LiteLLM's SSO Debug Flow exposes the `json.dumps` output of the `ui_sso.py` management endpoint to unauthenticated remote attackers, enabling authentication bypass against versions up to 1.82.2. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms this is network-exploitable with no privileges or user interaction required. A public proof-of-concept has been disclosed on GitHub, elevating practical risk beyond the moderate base score alone; no active exploitation has been confirmed by CISA KEV at the time of analysis.	MEDIUM	5.5	0.4%	48	PoC No patch
CVE-2026-42203	Server-side template injection in LiteLLM Proxy versions 1.80.5 through 1.83.6 allows authenticated users to execute arbitrary code via the POST /prompts/test endpoint. Any user with a valid proxy API key can submit malicious prompt templates that escape sandboxing and run commands in the proxy server process, exposing environment secrets like provider API keys and database credentials. This vulnerability affects deployments using LiteLLM as an AI gateway proxy server. No active exploitation confirmed (not in CISA KEV), but GitHub advisory and patch are publicly available, increasing exploit likelihood. CVSS 8.6 (High) with network attack vector and low complexity, though PR:L requirement limits exposure to authenticated attackers only.	HIGH	8.6	0.0%	43
CVE-2026-84377	Credential exfiltration via SSRF in LiteLLM proxy (AI Gateway) prior to versions 1.88.6 and 1.96.2 allows any authenticated proxy user to redirect outbound LLM provider calls to an attacker-controlled endpoint, causing the proxy to transmit its operator-configured API keys and other secrets to that destination. Vulnerable routing parameters - api_base, base_url, model_list, fallbacks, and litellm_credential_name - could be injected through nested request fields, path values, and bracket-notation form data that incomplete validation across five proxy modules failed to intercept. No public exploit code has been identified at time of analysis; vendor-released patches are confirmed at versions 1.88.6 and 1.96.2.	MEDIUM	6.5	0.3%	33
CVE-2026-59820	Path traversal in LiteLLM's Skills archive extraction enables authenticated users with access to specific LLM API routes to write arbitrary files outside the intended server extraction directory by uploading a crafted ZIP archive containing path traversal entries. Affected versions are all LiteLLM releases prior to 1.83.7-stable; the CPE confirms the entire berriai/litellm product line is in scope. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the integrity and availability impact is rated High in the vendor-provided CVSS 4.0 vector, making this a meaningful risk for any LiteLLM deployment that exposes the Skills upload feature to untrusted authenticated users.	MEDIUM	6.1	0.3%	31
CVE-2026-12796	Insufficient session expiration in LiteLLM's SSO authentication flow exposes deployments running versions 1.82.0 through 1.82.2 to unauthorized persistent session access by low-privileged authenticated users. The flaw resides in the `get_redirect_response_from_openid` function within the OpenID Connect callback handling code, allowing manipulation of the SSO redirect response to bypass session lifetime enforcement. No confirmed active exploitation (not in CISA KEV), but a publicly available proof-of-concept exploit on GitHub lowers the barrier to abuse, and the CVSS 4.0 vector explicitly encodes the exploit availability modifier E:P.	LOW	2.1	0.3%	31	PoC No patch
CVE-2026-12770	Improper authorization in BerriAI LiteLLM versions 1.63.0-1.63.1 allows any authenticated user - holding any valid API key regardless of role - to perform admin-restricted operations on other users' API keys, including blocking, unblocking, and modifying budget limits via the `/key/block`, `/key/unblock`, and `/key/update` endpoints. The root cause, confirmed by GitHub PR #23781, is the complete absence of access-control enforcement on these endpoints despite their admin-only documentation. A publicly available proof-of-concept exploit exists on GitHub; this vulnerability is not in the CISA KEV catalog at time of analysis.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-12799	Improper authorization in BerriAI LiteLLM versions up to 1.82.2 allows authenticated low-privilege users to access user data beyond their permitted scope via the `ui_view_users` management endpoint - an incomplete remediation of the prior CVE-2025-0628 authorization bypass in the same function. A public proof-of-concept exploit is available on GitHub (YLChen-007), confirming practical exploitability. No active exploitation is confirmed (not in CISA KEV), and the authentication requirement (CVSS 4.0 PR:L) constrains the attacker pool to those already holding valid credentials on the target proxy.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-12772	Insufficient session expiration in LiteLLM's proxy authentication layer (versions 1.82.0 through 1.82.2) allows remote low-privileged users to reuse or manipulate session tokens generated by the PROXY_ADMIN API Key Generator beyond their intended validity window. The flaw resides in the `authenticate_user` function within `litellm/proxy/auth/login_utils.py`, where session/API key lifecycle management does not enforce expiration correctly per CWE-613. A public proof-of-concept exploit exists (GitHub gist), though no active exploitation has been confirmed via CISA KEV. The CVSS 4.0 score of 2.1 reflects a limited real-world blast radius despite the network-accessible attack vector.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-12774	Server-side request forgery in BerriAI LiteLLM versions up to 1.82.2 allows authenticated remote attackers to induce the proxy server to make arbitrary outbound HTTP requests by manipulating the MCP (Model Context Protocol) Server Connection Testing endpoint. The vulnerable function `_execute_with_mcp_client` in the experimental MCP server component fails to validate or restrict user-supplied connection targets, enabling internal network probing, potential access to cloud metadata services, and circumvention of network segmentation controls. A publicly available proof-of-concept exploit exists (GitHub gist by YLChen-007); no CISA KEV listing was present at time of analysis. The CVSS 4.0 reported score of 2.1 reflects threat-metric downgrade from E:P (proof-of-concept) and should not be taken as indicative of low inherent exploitability - the base network vector with low-privilege access represents a meaningful internal network exposure risk.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-12797	Incorrect authorization in BerriAI LiteLLM's enterprise banned keywords hook allows remote low-privileged authenticated users to bypass prompt content filtering by manipulating the `prompt` argument to the `async_pre_call_hook` function in `enterprise/enterprise_hooks/banned_keywords.py`. All versions in the 1.82.x series up to and including 1.82.5 are confirmed affected. A public proof-of-concept exploit is available via GitHub Gist, materially increasing the risk for enterprise deployments that rely on the banned keywords feature as a compliance or safety enforcement boundary; no confirmed CISA KEV listing exists at time of analysis.
