PYSEC-2026-4112 JupyterLab: Cross-site scripting (XSS) in JupyterLab via notebook cells pasted from the system clipboard

Description JupyterLab 4.5.0 enabled copying and pasing cells through the system clipboard. The paste path parses clipboard text as cell JSON and inserts the cells without clearing metadata.trusted, so a payload can declare its own output as trusted. JupyterLab does not sanitize a trusted output...

PYSEC-2026-4113 Oauthlib : Unsafe JSONP callback injection in RevocationEndpoint allows arbitrary JavaScript response generation

Summary When enablejsonp=True, oauthlib's RevocationEndpoint reflects the user-supplied callback parameter directly into JavaScript response bodies on both success and error paths without validating that it is a legal JSONP callback name. This allows arbitrary JavaScript response generation inste...

PYSEC-2026-4182 Zapros: Streaming decoders ignored the requested chunk size, allowing a single compressed response chunk to allocate unbounded memory (decompression bomb)

Impact Denial of service via memory exhaustion. Affects all callers who streamed compressed responses relying on the chunk size — explicit iterbyteschunksize=... or the default — to bound memory. The decoder ignored that bound, so a chunk could be far larger than requested and a single compressed...

PYSEC-2026-4171 Soup Sieve: Polynomial-time ReDoS (O(n²)) in the whitespace/comment trimming regex `RE_WS_END` (triggers on VALID selectors)

Summary Before 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,...

Summary lmdeploy = 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. When a user loads the model with...

PYSEC-2026-4046 djust: WebSocket/runtime reconstructed request omits the client Host, causing host/subdomain TenantResolvers to misresolve the tenant on the live path

Impact The 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...

PYSEC-2026-4041 djust has broken object-level access control (IDOR)

Impact djust'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...

PYSEC-2026-4036 djust: Multi-tenant isolation fails open on the WebSocket/SSE path, disclosing other tenants' data

Impact djust.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...

PYSEC-2026-3878 Open WebUI: Server-side fetches reach blocked and internal hosts via unvalidated HTTP redirect targets

Summary Open WebUI protects server-side web fetches with two controls: the operator's list of excluded hosts, and a check that refuses private and internal addresses. Neither control was applied to the destination of an HTTP redirect. On a deployment where redirect following is enabled, any...

PYSEC-2026-3879 Open WebUI: Any authenticated user can hang the server via a cyclic chat message history

Summary Chat histories are stored as an unvalidated JSON object. The walk that reconstructs a chat's message chain detected repeats using each message's own id field while moving through the history by map key, so a message that simply omitted id was never recorded as visited. A history whose...

PYSEC-2026-3908 Prowler: Stored XSS in HTML reports through unescaped cloud resource tags

Summary Prowler's HTML output formatter inserts finding.resourcetags into the generated report without HTML escaping. A cloud principal who can create or edit a resource tag in an account that is later scanned can store HTML or JavaScript in that tag. When another user opens the generated Prowler...

PYSEC-2026-3845 HTTPX2: Secure WebSocket traffic sent without TLS through SOCKS proxies

Summary httpcore2 does not start TLS for wss:// connections routed through a SOCKS5 proxy. The WebSocket opening handshake and all subsequent frames are sent in plaintext through the proxy path, despite the caller selecting the secure wss scheme. The transport flaw affects httpcore2 releases befo...
