In the telecommunication world, security is not just a necessity—it’s a foundation of trust. Telcos are the backbone for global communication, transporting sensitive data in real time across large networks. Any vulnerability in this critical infrastructure can lead to data breaches, exposing confidential information. With billions of connected devices, from mobile phones to IoT, the potential of misuse of data can seriously impact national security. Protecting the network from threats isn't merely a technical challenge, it's a vital part of the job.User management, hardening, network secur

### Summary When validating a request with a multipart/form-data schema, if the OpenAPI schema allows it, an attacker can upload a crafted ZIP file (e.g., a ZIP bomb), causing the server to consume all available system memory. ### Details The root cause comes from the [ZipFileBodyDecoder](https://github.com/getkin/kin-openapi/blob/6da871e0e170b7637eb568c265c08bc2b5d6e7a3/openapi3filter/req_resp_decoder.go#L1523), which is registered [automatically](https://github.com/getkin/kin-openapi/blob/6da871e0e170b7637eb568c265c08bc2b5d6e7a3/openapi3filter/req_resp_decoder.go#L1275) by the module (contrary to what the [documentation says](https://github.com/getkin/kin-openapi?tab=readme-ov-file#custom-content-type-for-body-of-http-requestresponse). ### PoC To reproduce the vulnerability, you can use the following OpenAPI schema: ```yaml openapi: 3.0.0 info: title: 'Validator' version: 0.0.1 paths: /: post: requestBody: required: true content: multipar...

### Summary The `fast-jwt` library does not properly validate the `iss` claim based on the RFC https://datatracker.ietf.org/doc/html/rfc7519#page-9. #### Details The `iss` (issuer) claim validation within the fast-jwt library permits an array of strings as a valid `iss` value. This design flaw enables a potential attack where a malicious actor crafts a JWT with an `iss` claim structured as `['https://attacker-domain/', 'https://valid-iss']`. Due to the permissive validation, the JWT will be deemed valid. Furthermore, if the application relies on external libraries like `get-jwks` that do not independently validate the `iss` claim, the attacker can leverage this vulnerability to forge a JWT that will be accepted by the victim application. Essentially, the attacker can insert their own domain into the `iss` array, alongside the legitimate issuer, and bypass the intended security checks. #### PoC Take a server running the following code: ```js const express = require('express') const ...

Mattermost versions 9.11.x <= 9.11.8 fail to properly perform authorization of the Viewer role which allows an attacker with the Viewer role configured with No Access to Reporting to still view team and site statistics.

**Description:** The `feldman_vss` library contains timing side-channel vulnerabilities in its matrix operations, specifically within the `_find_secure_pivot` function and potentially other parts of `_secure_matrix_solve`. These vulnerabilities are due to Python's execution model, which does not guarantee constant-time execution. An attacker with the ability to measure the execution time of these functions (e.g., through repeated calls with carefully crafted inputs) could potentially recover secret information used in the Verifiable Secret Sharing (VSS) scheme. The `_find_secure_pivot` function, used during Gaussian elimination in `_secure_matrix_solve`, attempts to find a non-zero pivot element. However, the conditional statement `if matrix[row][col] != 0 and row_random < min_value:` has execution time that depends on the value of `matrix[row][col]`. This timing difference can be exploited by an attacker. The `constant_time_compare` function in this file also does not provide a con...
