CVE-2026-1776: Camaleon CMS AWS Uploader Authenticated Path Traversal Arbitrary File Read

Noroxi assessment

Priority: Monitor (action score 24/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.77% (FIRST EPSS); higher than 55.7% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

Camaleon CMS versions 2.4.5.0 through 2.9.0, prior to commit f54a77e, contain a path traversal vulnerability in the AWS S3 uploader implementation that allows authenticated users to read arbitrary files from the web server’s filesystem. The issue occurs in the download_private_file functionality when the application is configured to use the CamaleonCmsAwsUploader backend. Unlike the local uploader implementation, the AWS uploader does not validate file paths with valid_folder_path?, allowing directory traversal sequences to be supplied via the file parameter. As a result, any authenticated user, including low-privileged registered users, can access sensitive files such as /etc/passwd. This issue represents a bypass of the incomplete fix for CVE-2024-46987 and affects deployments using the AWS S3 storage backend.
