Cross Site Scripting vulnerability found in Ehuacui BBS allows attackers to cause a denial of service via a crafted payload in the login parameter.

Buffer Overflow found in Nginx NJS allows a remote attacker to execute arbitrary code via the njs_object_property parameter of the njs/njs_vm.c function.

Buffer Overflow vulnerabilty found in Nginx NJS v.0feca92 allows a remote attacker to execute arbitrary code via the njs_module_read in the njs_module.c file.

### Impact A memory exhaustion bug exists in Wagtail's handling of uploaded images and documents. For both images and documents, files are loaded into memory during upload for additional processing. A user with access to upload images or documents through the Wagtail admin interface could upload a file so large that it results in a crash or denial of service. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. It can only be exploited by admin users with permission to upload images or documents. Image uploads are [restricted to 10MB by default](https://docs.wagtail.org/en/stable/reference/settings.html#wagtailimages-max-upload-size), however this validation only happens on the frontend and on the backend after the vulnerable code. ### Patches Patched versions have been released as Wagtail 4.1.4 (for the LTS 4.1 branch) and Wagtail 4.2.2 (for the current 4.2 branch). ### Workarounds Site owners who are unable to upgrade to the ne...

request-baskets up to v1.2.1 was discovered to contain a Server-Side Request Forgery (SSRF) via the component /api/baskets/{name}. This vulnerability allows attackers to access network resources and sensitive information via a crafted API request.

openapi-generator up to v6.4.0 was discovered to contain a Server-Side Request Forgery (SSRF) via the component /api/gen/clients/{language}. This vulnerability allows attackers to access network resources and sensitive information via a crafted API request.

There is a possible Denial of Service (DoS) vulnerability in the unpoly-rails gem that implements the [Unpoly server protocol](https://unpoly.com/up.protocol) for Rails applications. ### Impact This issues affects Rails applications that operate as an upstream of a load balancer's that uses [passive health checks](https://docs.nginx.com/nginx/admin-guide/load-balancer/http-health-check/#passive-health-checks). The [unpoly-rails](https://github.com/unpoly/unpoly-rails/) gem echoes the request URL as an `X-Up-Location` response header. By making a request with exceedingly long URLs (paths or query string), an attacker can cause unpoly-rails to write a exceedingly large response header. If the response header is too large to be parsed by a load balancer downstream of the Rails application, it may cause the load balancer to remove the upstream from a load balancing group. This causes that application instance to become unavailable until a configured timeout is reached or until an activ...

Insertion of Sensitive Information into log file vulnerability in NGINX Agent. NGINX Agent version 2.0 before 2.23.3 inserts sensitive information into a log file. An authenticated attacker with local access to read agent log files may gain access to private keys. This issue is only exposed when the non-default trace level logging is enabled. Note: NGINX Agent is included with NGINX Instance Manager and used in conjunction with NGINX API Connectivity Manager, and NGINX Management Suite Security Monitoring.

### Summary The vulnerability resides on the Nginx config file: https://github.com/heartexlabs/label-studio/blob/53944e6bcede75ca5c102d655013f2e5238e85e6/deploy/default.conf#L119 The pattern on location /static indicates a popular misconfiguration on Nginx servers presented in 2018 originally by Orange Tsai. This vulnerability allows an attacker to use a single path traversal payload in the matched location to traverse one directory above. This vulnerability only happens due to the location /static directive not having a slash `/` at the end, the following code shows an example of a safe configuration: ```nginx location /static/ { [...] ``` The vulnerability works because Nginx will think that `/static../` is a directory that should also be aliased to the folder, allowing /static/../ to be reached. In Label Studio's case, this means all files on /label_studio/core/ are exposed. Of course, this means that only Label Studio instances that were deployed using the default nginx files int...
