### Summary `image-size` is vulnerable to a Denial of Service vulnerability when processing specially crafted images. The issue occurs because of an infine loop in `findBox` when processing certain images with a box with size `0`. ### Details If the first bytes of the input does not match any bytes in `firstBytes`, then the package tries to validate the image using other handlers: ```js // https://github.com/image-size/image-size/blob/v1.2.0/lib/detector.ts#L20-L31 export function detector(input: Uint8Array): imageType | undefined { const byte = input[0] if (byte in firstBytes) { const type = firstBytes[byte] if (type && typeHandlers[type].validate(input)) { return type } } const finder = (key: imageType) => typeHandlers[key].validate(input) //<-- return keys.find(finder) } ``` Some handlers that call `findBox` to validate or calculate the image size are `jxl`, `heif` and `jp2`. `JXL` handler calls `findBox` inside `validate`. To reach the `findBox` ...

About Remote Code Execution – Apache Tomcat (CVE-2025-24813) vulnerability. Apache Tomcat is an open-source software that provides a platform for Java web applications. The vulnerability allows a remote attacker to upload and execute arbitrary files on the server due to flaws in the handling of uploaded session files and the deserialization mechanism. 🔻 The vendor’s […]

Cybersecurity researchers have discovered an updated version of a malware loader called Hijack Loader that implements new features to evade detection and establish persistence on compromised systems. "Hijack Loader released a new module that implements call stack spoofing to hide the origin of function calls (e.g., API and system calls)," Zscaler ThreatLabz researcher Muhammed Irfan V A said in

### Summary The PROXY command is accepted multiple times, allowing a client to spoof its IP address when the proxy protocol is being used. ### Details When ProxyOn is enabled, [it looks like the PROXY command will be accepted multiple times](https://github.com/phires/go-guerrilla/blob/fca3b2d8957a746997c7e71fca39004f5c96e91f/server.go#L495), with later invocations overriding earlier ones. The proxy protocol only supports one initial PROXY header; anything after that is considered part of the exchange between client and server, so the client is free to send further PROXY commands with whatever data it pleases. go-guerrilla will treat these as coming from the reverse proxy, allowing a client to spoof its IP address. Note that the format of the PROXY header is [well-defined](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt). It probably shouldn't be treated as an SMTP command; parsing it the same way is likely to result in odd behavior and could lead to other vulnerabili...

### Impact We received a report about a vulnerability in Remix/React Router that affects all Remix 2 and React Router 7 consumers using the Express adapter. Basically, this vulnerability allows anyone to spoof the URL used in an incoming `Request` by putting a URL pathname in the port section of a URL that is part of a `Host` or `X-Forwarded-Host` header sent to a Remix/React Router request handler. ### Patches This issue has been patched and released in Remix 2.16.3 React Router 7.4.1. ### Credits - Rachid Allam (zhero;) - Yasser Allam (inzo_)

### Impact alizeait unflatto <= 1.0.2 was discovered to contain a prototype pollution via the method exports.unflatto at /dist/index.js. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties. ### Patches The problem has been patched in 1.0.3 ### References https://github.com/advisories/GHSA-799q-f2px-wx8c

### Impact Versions after 2.x and before 3.x of io.jooby:jooby-pac4j can cause deserialization of untrusted data ### Patches - 2.17.0 (2.x) - 3.7.0 (3.x) ### Workarounds - Not using io.jooby:jooby-pac4j until it gets patches. - Check what values you put/save on session ### References Version 2.x: https://github.com/jooby-project/jooby/blob/v2.x/modules/jooby-pac4j/src/main/java/io/jooby/internal/pac4j/SessionStoreImpl.java#L39-L45 Version 3.x: https://github.com/jooby-project/jooby/blob/v3.6.1/modules/jooby-pac4j/src/main/java/io/jooby/internal/pac4j/SessionStoreImpl.java#L77-L84 ### Cause In module pac4j io.jooby.internal.pac4j.SessionStoreImpl#get , it is used to handle sessions , and trying to get key value. In strToObject function ,it's trying to deserialize value when value starts with "b64~" , which might cause deserialization of untrusted data.
