GHSA-HX4H-VR3M-45VH n8n: Prototype Pollution via VM Expression Engine Sandbox Escape Leads to Denial of Service
Impact An authenticated user able to create or edit a workflow expression could abuse the expression engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process, leading to a denial of service. Both self-hosted and cloud instances runni...
GHSA-MQ3M-F8X3-579W n8n: Cross-Issuer Token Exchange Account Binding via Subject-Only Identity Resolution
Impact When an n8n instance is configured with more than one trusted token-exchange issuer, external identities are resolved to local accounts using only the JWT sub claim, ignoring the issuer iss. As a result, two different issuers that emit the same subject value map to the same local account. ...
GHSA-9R8P-H6CC-6QHM n8n: Google Service Account Private Key Exposed in JWT Header
Impact When n8n was configured with a Google Service Account key, the full PEM private key was mistakenly placed in the JWT header's kid field which should only have held a key identifier. Since JWT headers were Base64-encoded rather than encrypted, the key could be recovered by anything that...
CVE-2026-16221
Impact: fast-uri versions from 2.3.1 through 4.1.0 including the 3.x line up to 3.1.3 and the 2.x line up to 2.4.2 do not treat a literal backslash character U+005C as an authority delimiter. Node's native WHATWG URL parser, used by fetch, undici, and Node's http and https clients, normalizes the...
DEBIAN-CVE-2026-16221
Impact: fast-uri versions from 2.3.1 through 4.1.0 including the 3.x line up to 3.1.3 and the 2.x line up to 2.4.2 do not treat a literal backslash character U+005C as an authority delimiter. Node's native WHATWG URL parser, used by fetch, undici, and Node's http and https clients, normalizes the...
CVE-2026-15631 @fastify/http-proxy vulnerable to prefix escape via WebSocket path traversal
Impact: @fastify/http-proxy versions from 9.4.0 up to and including 11.5.0 fail to validate the resolved WebSocket destination path against the configured rewrite prefix. The WebSocket routing path in WebSocketProxy.findUpstream resolves the destination via the WHATWG URL constructor, which...
dd-trace-py: Improper parsing of W3C baggage headers may lead to DoS
Impact Datadog tracing libraries that implement W3C baggage propagation parse incoming baggage HTTP headers without enforcing item-count or byte-size limits on the extract path. The DDTRACEBAGGAGEMAXITEMS default 64 and DDTRACEBAGGAGEMAXBYTES default 8192 limits were applied only to baggage...
GHSA-GHHP-3QVG-889P websocket-driver: Memory exhaustion via abuse of protocol length headers
Impact The frame format in draft versions of the WebSocket protocol includes a length header that allows an arbitrarily large integer to be encoded as a sequence of bytes with the high bit set. By sending an indefinite sequence of bytes with values 0x80 or above, a server or client can make the...
GHSA-F5PF-Q7C7-M3VV Pixeldrain API key shared with unverified thirdparty sites
Summary When processing Pixeldrain URLs, cyberdrop-dl-patched could send an Authorization header that includes the user's API key to unverified hosts. Details Pixeldrain offers several alternative domains in case the user's ISP blocks the primary domain. To support this, requests made by...
PYSEC-2026-3049 Recce server has unauthenticated SQL execution that allows local file read/write through DuckDB
Impact Recce OSS server deployments that expose the server to an untrusted network without authentication are vulnerable to unauthenticated SQL execution through the query run API. When Recce is configured with a DuckDB-backed project, an attacker can use DuckDB filesystem primitives to read and...
PYSEC-2026-3435 python-zeroconf: Unbounded TC-deferred queue allows LAN-local memory exhaustion via spoofed-source flood
Impact AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query in self.deferredaddr and armed a per-addr timer in self.timersaddr that flushed the reassembled query within 500 ms RFC 6762 §18.5. Neither the per-addr list nor the number of distinct addr keys was capped, and...
zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion
ImpactDNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dict keyed by strsys.excinfo1. The seven IncomingDecodeError messages raised from readname / decodelabelsatoffset RFC 6762 §18 name-decoding error paths all embed self.source — the...
PYSEC-2026-2533 LTI JupyterHub Authenticator: Unbounded Memory Growth via Nonce Storage (Denial of Service)
Summary The LTI 1.1 validator stores OAuth nonces in a class-level dictionary that grows without bounds. Nonces are added before signature validation, so an attacker with knowledge of a valid consumer key can send repeated requests with unique nonces to gradually exhaust server memory, causing a...
PYSEC-2026-3432 yt-dlp: Arbitrary Command Injection when using the `--netrc-cmd` option
Summary When yt-dlp's --netrc-cmd command-line option or netrccmd Python API parameter is used, an attacker could achieve arbitrary command injection on the user's system with a maliciously crafted URL. Impact yt-dlp maintainers assume the impact of this vulnerability to be high for anyone who us...
EUVD-2026-43267
A vulnerability was detected in kLOsk adloop up to 0.9.0. This vulnerability affects the function validateurls of the file src/adloop/ads/write.py. Performing a manipulation of the argument finalurl results in server-side request forgery. The attack may be initiated remotely. The exploit is now...
PT-2026-60048
Impact DNSCache. async add inserted every response record into cache, expirations, expire heap, and service cache with no cap on entry count. The only pre-existing protection was a PTR TTL floor DNS PTR MIN TTL = 1125 s, RFC 6762 §10, which actually prolonged attacker-injected records, and a...

GHSA-PW9M-5JXM-XR6H Better Auth: OAuth refresh-token replay via missing client authentication on oidc-provider and mcp plugins
Am I affected? Users are affected if all of the following are true: - Their application uses better-auth and has enabled at least one of: oidcProvider imported from better-auth/plugins/oidc-provider, or mcp imported from better-auth/plugins/mcp. - Their application has at least one confidential...
SUSE CVE-2026-6734
Impact: When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without verifying that the pool's origin matches the requested origin. All requests are dispatched through the pool connected to the first origin, regardless of the intended destination. This caus...
