Soup Sieve: Polynomial-time ReDoS (O(n²)) in the `IDENTIFIER` / `VALUE` selector sub-patterns

Summarysoupsieve compiles CSS selector strings with a set of hand-written regular expressions. The shared IDENTIFIER sub-pattern also embedded in VALUE, and therefore in attribute selectors places two adjacent quantified groups over overlapping character classes: ?:classA|ESC+?:classB|ESC, where...

AnyIO process-pool workers can block indefinitely on undrained stderr

ImpactAnyIO starts process-pool workers with stderr connected to a pipe but never drains that pipe. The worker redirects stdin and stdout to /dev/null to protect its protocol, but does not redirect stderr even though the documentation says all three standard streams are redirected. Worker code th...

LMDeploy vulnerable to arbitrary code execution via eval() of untrusted quant_dtype in model config loading

Summarylmdeploy = latest contains a code injection vulnerability in lmdeploy/pytorch/config.py line 620 that allows an attacker to execute arbitrary Python code by publishing a malicious HuggingFace model with a crafted quantizationconfig.quantdtype value.

Soup Sieve: Polynomial-time ReDoS (O(n²)) in the whitespace/comment trimming regex `RE_WS_END` (triggers on VALID selectors)

SummaryBefore tokenizing, selectoriter trims leading/trailing whitespace and comments by running two regexes over the whole raw selector with .search. The trailing one, REWSEND = re.compiler'WSC$', is anchored only at the end $, not the start. Because .search retries the pattern at every offset, ...

AnyIO: TLSStream IDNA 2003 host name encoding enables potential TLS certificate spoofing

ImpactServices using internationalized non-ASCII domain names are potentially vulnerable to TLS connections made from AnyIO's connecttcp or directly via TLSStream.wrap where the connection has through other means been hijacked and redirected to a malicious server. The attacker would obtain a...

Jupyter Server: 5xx request logging leaks token-bearing Referer header values

SummaryWhen a request returns a 500, jupyterserver/log.py logs a small JSON block of request headers. The Referer header was copied into it as-is, so a token in the Referer URL ended up in the logs in plain text. ImpactAnyone who can read the server logs can pick tokens out of these 500 entries...

Mnemosyne has JWT signature verification bypass sync server that allows authentication bypass

SummaryThe Mnemosyne sync server's authentication check decoded JWT bearer tokens but never verified their HMAC-SHA256 signatures. Any well-formed token was accepted, allowing an unauthenticated attacker to impersonate any user and read or modify their sync data.Severity: CriticalCVSS 3.1:...

PyZMQ implements recvpyobj using Python pickledeserialization, which can execute arbitrary code while reconstructingan object.The peer address used by th...

AnyIO run_process/open_process ignores extra_groups and can retain parent supplementary groups

AnyIO 4.14.0 accepts the POSIX extragroups argument on anyio.runprocess and anyio.openprocess, but openprocess forwards the wrong variable to the backend: when extragroups is not None, it assigns kwargs"extragroups" = group instead of extragroups. As a result, callers cannot reliably clear or set...

LiteLLM Proxy has server-side request forgery via the `user_config` request parameter

SummaryA server-side request forgery in LiteLLM Proxy lets an authenticated caller redirect theproxy's outbound request to a host of their choosing by smuggling an apibase inside theuserconfig request body, bypassing the existing parameter guard. DetailsLiteLLM Proxy validates request bodies with...

ImpactRestrictedPython could allow a sandbox escape when a policy exposes the standard library string module, or otherwise exposes string.Formatter, to restricted code.string.Formatter field resolution methods such as getfield can perform attribute and item traversal internally and return live...

sanic chunked trailer request smuggling allows hidden second request execution

DescriptionSanic's HTTP/1.1 chunked-body handling does not fully consume the trailer-part after the terminating 0\r\n chunk. Because of that, attacker-controlled bytes left in the connection buffer after the first chunked request can be interpreted as the start of a new HTTP request on the same...

djust: WebSocket/runtime reconstructed request omits the client Host, causing host/subdomain TenantResolvers to misresolve the tenant on the live path

ImpactThe WebSocket handlemount and ViewRuntime.buildrequest rebuild an HttpRequest via RequestFactory.get... with no HTTPHOST, so request.gethost defaulted to "testserver" on the live path. Host/subdomain/domain TenantResolvers then misresolved the tenant — None on the live path while the HTTP...

vLLM: Request-selected PyNvVideoCodec GPU decode bypasses static VRAM reservation

SummaryCurrent vLLM main lets an inference request choose the PyNvVideoCodec GPU video decoder through mediaiokwargs.video.videobackend, but engine GPU memory reservation is computed only from static startup configuration and VLLMVIDEOLOADERBACKEND. If the server starts with the default...

djust has an unauthenticated arbitrary module import via the WebSocket/SSE view-mount path

ImpactThe djust live transport resolves the LiveView to mount from a client-supplied dotted path by calling importmodulepath, .... The module is imported — running its top-level code import side effects — before the framework checks that the resolved object is a LiveView subclass and before any...

Zope AccessControl vulnerable to information disclosure through Python string `format` and `format_map` functions

ImpactPython's string format functionality allows someone controlling the format string to "read" objects accessible recursively via attribute access and subscription from accessible objects. Those attribute accesses and subscriptions use Python's full blown getattr and getitem, not the policy...

djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)

ImpactFor views that opt into state snapshots, the snapshot statejson embedded in the client page was restored on reconnect as trusted view state with no integrity check. A client could edit the unsigned statejson in their page and return it in the reconnect mount frame to inject arbitrary view...

djust has broken object-level access control (IDOR)

Impactdjust's per-object authorization getobject + hasobjectpermission, ADR-017 was enforced on the WebSocket mount and event paths but not on three other render entry points: a the initial HTTP GET render, b SPA urlchange navigation, and c % liverender % embedded child views. An authenticated us...

djust: SSE sessions are not bound to the authenticated user; the client-chosen session_id is the sole authorization capability (session hijack)

ImpactSSE sessions were keyed solely by a client-chosen sessionid with no binding to the authenticated user — a control the WebSocket transport has but that was dropped on SSE. An attacker who learns or a victim who leaks a sessionid could connect to the message endpoint and dispatch event handle...

djust is vulnerable to stored/reflected XSS via javascript: URLs in built-in component template tags

ImpactMany djust built-in component template tags djust.components.templatetags. render a developer/user-supplied URL into an href / action attribute, HTML-escaping it with conditionalescape but never validating the URL scheme. HTML escaping prevents attribute breakout but does not neutralize a...

DescriptionThe LMdeployimplements anrpc server AsyncRPCServer in zmqrpc.pyfor supporting the RPC communications. In its core functionalitycallandresponse, I found it will directly use thepickles.loadsto deserialize the received messages without any sanitization, hence resulting in a remote code...

djust has Cross-Site Request Forgery on the Server-Sent-Events transport: a cross-origin page can drive a victim-authenticated SSE session

ImpactThe SSE client→server POST endpoints are @csrfexempt and the SSE GET stream endpoint had no Origin check, so a cross-origin page could drive a victim-cookie-authenticated SSE session: force the victim's browser to GET the stream URL which creates and mounts a LiveView as the victim and POST...

djust has an authorization bypass on the WebSocket/SSE mount path

ImpactThe live WebSocket transport authorizes a mount via checkviewauth, not Django's View.dispatch chain. As a result, standard Django authorization — LoginRequiredMixin, PermissionRequiredMixin, UserPassesTestMixin, @methoddecoratorloginrequired, name="dispatch", and custom dispatch guards — an...

djust's Django model serialization has no sensitive-field denylist: password hashes, privilege flags, and PII on a public view attribute are sent to the client

ImpactWhen a Django Model instance is assigned to a public view attribute, djust serialized it to the client with no sensitive-field denylist — sending fields such as password the hash, privilege flags e.g. isstaff / issuperuser, tokens, and other PII to the browser. Because exposing model object...

djust: Multi-tenant isolation fails open on the WebSocket/SSE path, disclosing other tenants' data

Impactdjust.tenants isolation was enforced only on the HTTP path. The current tenant was stored in threading.local and set exclusively by the HTTP-only TenantMiddleware, so on the live WebSocket/SSE path getcurrenttenant was always None during mount and every event handler — and the tenant-aware...

Open WebUI: A user's session cookies are sent to tool servers configured for bearer authentication

SummaryWhen more than one external tool server is reachable in the same request, a tool call to a server configured for bearer authentication can arrive carrying the calling user's Open WebUI session cookies alongside that server's own key. The cookie jar is built per connection, but the callable...

MySQL MCP Server: Missing Origin/Host Validation in SSE Transport Enables Unauthenticated SQL Execution (DNS Rebinding / Direct Exposure)

SummaryIn SSE/HTTP transport mode, mysqlmcpserver constructs SseServerTransport without passing securitysettings. As a result, the MCP Python SDK's DNS-rebinding protection Origin/Host header validation is disabled; the Starlette application has no CORS or TrustedHost middleware; and the service...

ESPHome Device Builder: Renamed auth env vars silently disable dashboard authentication on upgrade

SummaryThe dashboard reads its authentication credentials from $ESPHOMEUSERNAME and $ESPHOMEPASSWORD. Earlier versions, and the legacy esphome dashboard, read the bare $USERNAME and $PASSWORD instead. When the env vars were renamed the bare names were dropped with no fallback, so an operator who...

Open WebUI: Admin demoted through SSO role sync keeps read and write access to all users' notes

SummaryA user who is demoted from admin by an identity provider keeps admin-level read and write access to every user's notes, over any Socket.IO connection that was already open when the demotion happened. Open WebUI caches the user's role on the socket at connection time, and the two SSO...

Open WebUI: Any authenticated user can start a non-terminating request via a folder parent cycle

SummaryAny authenticated user can move one of their own folders under itself, leaving a loop in their folder tree. The re-parent endpoint performed no check that the new parent was not the folder itself or one of its own subfolders, and the folder tree walks did not track which folders they had...

Open WebUI: Users denied by the OAuth role policy can still sign in via token exchange

SummaryOpen WebUI's OAuth token exchange endpoint issues a session for a provider access token without running the OAuth role management that the normal OAuth login callback runs. A user whose provider roles the login callback would refuse, or would demote, could still obtain a working session at...

djust's observability endpoints are network-exposed: the localhost gate is an opt-in middleware the docs omit, and the views enforce only DEBUG

Impactdjust's observability endpoints expose live view/session state and a remote method-invocation surface evalhandler. The localhost restriction was an opt-in middleware that the documented setup omits; the views themselves enforced only DEBUG. In the misconfigured-but-documented scenario DEBUG...

Open WebUI: Unauthenticated requests can stall the server via uncached OIDC fetches in back-channel logout

SummaryThe OIDC back-channel logout endpoint is unauthenticated by design, because the identity provider calls it without a browser session. Before checking whether the submitted logout token was genuine, the handler fetched the provider's discovery document and its signing keys over the network,...
