Insecure Temporary File in SWHKD

SWHKD is a display protocol-independent hotkey daemon made in Rust. In SWHKD versions 1.1.5 and prior, SWHKD uses the /tmp/swhkd.pid pathname. As /tmp is accessible to all users, there can be an information leak or denial of service. No known workarounds exist. A patch is available on the 1.1.0...

9router /v1 APIs has unauthenticated access via reverse proxy locality collapse

9router treats local loopback requests as trusted and allows access to /v1/ without an API key. In a documented/common reverse-proxy deployment where nginx forwards public traffic to the backend via 127.0.0.1, external non-Origin requests are misclassified as local. This allows unauthenticated...

Etcd Gateway TLS endpoint validation only confirms TCP reachability

Vulnerability type Cryptography Workarounds Refer to the gateway documentation. The vulnerability was spotted due to unclear documentation of how the gateway handles endpoints validation. Detail Secure endpoint validation is performed by the etcd gateway start command when the --discovery-srv fla...

Etcd auth Inaccurate logging of authentication attempts for users with CN-based auth only

Vulnerability type Logging Detail etcd users who have no password can authenticate only through a client certificate. When such users try to authenticate into etcd using the Authenticate endpoint, errors are logged with insufficient information regarding why the authentication failed, and may be...

Gitea SSH Key Parser Denial of Service

Gitea's SSH key ingestion endpoint accepts keys in RFC 4716 SSH2 format and normalises them before storage. The normalisation function contains an ON² string concatenation loop with no input size limit, meaning a single malicious key submission can force the server to perform an amount of work th...

Missing connection timeout in Aardvark-dns

A flaw was found in Aardvark-dns versions 1.12.0 and 1.12.1. They contain a denial of service vulnerability due to serial processing of TCP DNS queries. This flaw allows a malicious client to keep a TCP connection open indefinitely, causing other DNS queries to time out and resulting in a denial ...

abomonation transmutes &T to and from &[u8] without sufficient constraints

This transmute is at the core of the abomonation crates. It's so easy to use it to violate alignment requirements that no test in the crate's test suite passes under miri. The use of this transmute in serialization/deserialization also incorrectly assumes that the layout of a reprRust type is...

Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')

c3p0 version 0.9.5.4 may be exploited by a billion laughs attack when loading XML configuration due to missing protections against recursive entity expansion when loading configuration...

9router: Kiro region injection allows authenticated SSRF with Authorization header forwarding

The Kiro API-key validation endpoint builds an upstream URL using a user-controlled region value. By supplying a crafted region such as kiro-canary.local:8443, an authenticated attacker can cause 9router to send the Kiro validation request to an attacker-controlled host under the constructed...

9router: Mass assignment in PATCH /api/settings allows authenticated authorization downgrade

The PATCH /api/settings endpoint writes the entire request body to persistent settings without a field whitelist. An authenticated user can set security-critical fields that are not meant to be modifiable here — notably requireLogin. Setting requireLogin: false disables authentication for the who...

Wire Swift runtime: negative LENGTH_DELIMITED length in skipGroup() crashes any protobuf-decoding service

Wire's Swift runtime Wire SPM/CocoaPods product, implemented by wire-runtime-swift did not reject a negative LENGTHDELIMITED field length while skipping an unknown protobuf group. A crafted 10-byte protobuf payload could cause ProtoReader.skipGroup to read a length-delimited field whose varint...

Crawl4AI: authentication bypass vulnerability due to a hardcoded default JWT signing key in the Docker API server

Crawl4AI before 0.8.7 contains an authentication bypass vulnerability due to a hardcoded default JWT signing key in the Docker API server. Attackers who know the default key can forge valid authentication tokens for any user, bypassing authentication and gaining full access to protected...

@aborruso/ckan-mcp-server has SSRF via DNS-name → internal IP — incomplete fix of CVE-2026-53509

The SSRF guard validateServerUrl added for CVE-2026-33060, extended for CVE-2026-53509 validates only the hostname string and never resolves DNS. Any caller-supplied serverurl whose hostname resolves to an internal address passes the guard, so the server issues requests to loopback and cloud...

9Router has a Login Brute-Force Lockout Bypass via Spoofable X-9r-Real-Ip Header

9router enforces a progressive login lockout 5 failed attempts → temporary 30s+ lock keyed on the client IP. The client IP used for this limiter is taken from the X-9r-Real-Ip request header, which is intended to be set only by the bundled custom-server.js layer from the unspoofable TCP socket...

yawkat LZ4 Java: Native library extraction to a shared temporary directory is vulnerable to file replacement by another local user

When no system-installed liblz4-java is found, net.jpountz.util.Native.load extracts the bundled native library to java.io.tmpdir and loads it with System.load. The path of the extracted library can be predicted before it is created, and the library file is opened without exclusive creation...

gitea-runner: workflow container.options passes host namespaces and capability flags to job container when privileged mode is disabled

actrunner appends workflow-controlled jobs..container.options directly to the Docker HostConfig for the job container. When runner privileged mode is disabled, only Privileged is forced false. Host namespace flags, capability expansion, and security profile overrides from workflow YAML are...

`Read` on uninitialized buffer in `fill_buf()` and `read_up_to()`

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. Arbitrary Read implementations can read from the uninitialized buffer memory exposure and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory...

yawkat LZ4 Java: LZ4BlockInputStream with stopOnEmptyBlock=false recurses once per empty block, causing StackOverflowError

When LZ4BlockInputStream is configured with stopOnEmptyBlock = false the mode for reading concatenated block streams, it handles each empty block by calling refill recursively. A long run of empty blocks exhausts the thread stack and throws StackOverflowError out of read or skip...

yawkat LZ4 Java: LZ4DecompressorWithLength allocates the unvalidated size from the 4-byte length header, so a 5-byte input triggers a 1 GiB allocation and OutOfMemoryError

LZ4DecompressorWithLength.decompressbyte, int allocates whatever size the 4-byte length header declares, before it reads a single byte of compressed data. A 5-byte input whose header says 0x40000000 makes the JVM commit a gigabyte and can cause heap exhaustion...

yawkat LZ4 Java: LZ4FrameInputStream reallocates block buffers for every frame, allowing CPU and GC amplification from small inputs

LZ4FrameInputStream allocates two new buffers of the frame's maximum block size, up to 4 MiB each, every time it reads a frame header. Because concatenated frames are read by default, an input made of many minimal empty frames forces about 8 MiB of zeroed heap allocation for every 11 input bytes...

yawkat LZ4 Java: LZ4BlockInputStream allocates an unvalidated compressed length from the stream header

LZ4BlockInputStream grows its compressed-input buffer to the attacker-controlled compressedLen value from the legacy LZ4Block stream header before reading any payload bytes. A header-only input can therefore trigger a near-2 GiB allocation and exhaust the JVM heap...

Capacitor Android and iOS: remote content can be loaded at the app origin via the internal HTTP proxy path

Capacitor's WebView navigation guard validated only the host and scheme of a target URL, not its path. Because the internal HTTP proxy path /capacitorhttpinterceptor is served at the application's own origin, a frame navigation to it was always treated as in-app navigation and allowed. Loading th...

Flask session does not add `Vary: Cookie` header when accessed in some ways

When the session object is accessed, Flask should set the Vary: Cookie header. This instructs caches not to cache the response, as it may contain information specific to a logged in user. This is handled in most cases, but some forms of access such as the Python in operator were overlooked. The...

Flask uses fallback key instead of current signing key

In Flask 3.1.0, the way fallback key configuration was handled resulted in the last fallback key being used for signing, rather than the current signing key. Signing is provided by the itsdangerous library. A list of keys can be passed, and it expects the last top key in the list to be the most...

CairoSVG: Quadratic-time DoS parsing a crafted SVG <path>

Rendering an untrusted SVG whose contains many segments is On² CPU. A single under 1 MiB burns tens of seconds. Two independent On² sites in cairosvg/path.py: 1. Tokenizer — the path-data parser consumes the d string with a while string: loop that repeatedly slices/re-scans the remaining string...
