CVE-2026-66066 Action Pack: Possible arbitrary file read and remote code execution in Active Storage variant processing

Action Pack is a framework for handling and responding to web requests. In versions prior to 7.2.3.2, 8.0.5.1 and 8.1.3.1, Active Storage does not disable libvips operations marked unsafe for untrusted content, allowing a crafted upload to invoke such an operation. Consuming applications are...

GHSA-XR9X-R78C-5HRM Active Storage has possible arbitrary file read and remote code execution in Active Storage variant processing

Impact In its default configuration, a Rails application that displays image variants may allow an unauthenticated attacker to read arbitrary files from the server, including the process environment. That environment typically holds secretkeybase and often credentials for external systems, which...

CVE-2026-46386 OpenProject: Pre-authentication RCE in openproject/openproject Docker image via default `SECRET_KEY_BASE=OVERWRITE_ME` and `cookies_serializer = :marshal`

OpenProject is open-source, web-based project management software. Prior to , the official openproject/openproject Docker image ships ENV SECRETKEYBASE=OVERWRITEME as the default Rails master key. Combined with cookiesserializer = :marshal, this gives any logged-in user a deterministic...

Authentication Bypass

Overview Affected versions of this package are vulnerable to Authentication Bypass when a password's salt is unknown. If the secret key base variable is somehow leaked, an attacker can become any user by misusing the masquerade back functionality of this Devise extension, something that is not...

GitLab File Read Remote Code Execution

This module provides remote code execution against GitLab Community Edition CE and Enterprise Edition EE. It combines an arbitrary file read to extract the Rails "secretkeybase", and gains remote code execution with a deserialization vulnerability of a signed 'experimentationsubjectid' cookie tha...

GitLab: information disclosure of secret_key_base via encoding charcters

@pareshparmar discovered an error page that was disclosing the value of the secretkeybase key of customers.gitlab.com to unauthenticated users, which would have allowed an attacker to arbitrarily decrypt signed cookies. So I was fuzzing one parameter with different type of encodings. And one...

Metasploit exposure remote code execution vulnerability: don't mess with me, I mad up my own all black-and-vulnerability warning-the black bar safety net

Just this week, Rapid7 community to publish two on the Metasploit framework security patches, by these two vulnerabilities, an attacker can remote unauthorized execution of arbitrary code. Currently, security researchers have issued the relevant POC attack code. ! Vulnerability: Metasploit Web...
