### Impact Prior to versions 6.4.2 and 5.6.8, puma exhibited incorrect behavior when parsing chunked transfer encoding bodies in a way that allowed HTTP request smuggling. Fixed versions limit the size of chunk extensions. Without this limit, an attacker could cause unbounded resource (CPU, network bandwidth) consumption. ### Patches The vulnerability has been fixed in 6.4.2 and 5.6.8. ### Workarounds No known workarounds. ### References * [HTTP Request Smuggling](https://portswigger.net/web-security/request-smuggling) * Open an issue in [Puma](https://github.com/puma/puma) * See our [security policy](https://github.com/puma/puma/security/policy)

### Summary Any unauthenticated user can browse to a specific URL to expose the Flask config, including the `SECRET_KEY` variable. ### Details Any unauthenticated user can browse to a specific URL to expose the Flask config, including the `SECRET_KEY` variable. ### PoC Run `pyload` in the default configuration by running the following command ``` pyload ``` Now browse to `http://localhost:8000/render/info.html`. Notice how the Flask configuration gets displayed.  I was quite amused by this finding. I think it's a very interesting coming together of things that is so unlikely to happen. Below I will detail my process a bit more. I was looking through the code to see how the authorization mechanism is implemented when I spotted this route, which can be accessed by any unauthenticated actor - https://github.com/pyload/pyload/blob/57d81930edb59177c60830ad8ac36a91d0ec4c4e/src/py...

### Summary A log injection vulnerability was identified in `pyload`. This vulnerability allows any unauthenticated actor to inject arbitrary messages into the logs gathered by `pyload`. ### Details `pyload` will generate a log entry when attempting to sign in with faulty credentials. This entry will be in the form of `Login failed for user 'USERNAME'`. However, when supplied with a username containing a newline, this newline is not properly escaped. Newlines are also the delimiter between log entries. This allows the attacker to inject new log entries into the log file. ### PoC Run `pyload` in the default configuration by running the following command ``` pyload ``` We can now sign in as the pyload user and view the logs at `http://localhost:8000/logs`.  Any unauthenticated attacker can now make the following request to inject arbitrary logs. ``` curl 'http://...

### Impact The main repo of fastify use [fast-content-type-parse](https://github.com/fastify/fast-content-type-parse) to parse request Content-Type, which will [trim after split](https://github.com/fastify/fast-content-type-parse/blob/2776d054dd48e9ce40b8d5e5ff9b46fee82b95f1/index.js#L59). The [fastify-reply-from](https://github.com/fastify/fastify-reply-from/blob/b79a22d6eb9a0b52cfbe8eb2cb22ad65f5a39e64/index.js#L118C14-L118C14) have not use this repo to unify the parse of Content-Type, which [won't trim](https://github.com/fastify/fastify-reply-from/blob/b79a22d6eb9a0b52cfbe8eb2cb22ad65f5a39e64/index.js#L118C14-L118C14). As a result, a reverse proxy server built with `@fastify/reply-from` could misinterpret the incoming body by passing an header `ContentType: application/json ; charset=utf-8`. This can lead to bypass of security checks. ### Patches `@fastify/reply-from` v9.6.0 include the fix. ### Workarounds There are no known workarounds. ### References Hackerone Report: ...

Cybersecurity is an infinite journey in a digital landscape that never ceases to change. According to Ponemon Institute1, “only 59% of organizations say their cybersecurity strategy has changed over the past two years.” This stagnation in strategy adaptation can be traced back to several key issues. Talent Retention Challenges: The cybersecurity field is rapidly advancing, requiring a

Digital expansion inevitably increases the external attack surface, making you susceptible to cyberthreats. Threat actors increasingly exploit the vulnerabilities stemming from software and infrastructure exposed to the internet; this ironically includes security tools, particularly firewalls and VPNs, which give attackers direct network access to execute their attacks. In fact, Gartner&

The U.S. National Institute of Standards and Technology (NIST) is calling attention to the privacy and security challenges that arise as a result of increased deployment of artificial intelligence (AI) systems in recent years. “These security and privacy challenges include the potential for adversarial manipulation of training data, adversarial exploitation of model vulnerabilities to
