We need to produce a JSON object with the specified fields. All fields are plain text strings. The input includes CVE-2026-66748 description, CVSS 4.0 vector (base only, no temporal/environmental), CWE-94, tags, POC publicly available, Patch available from vendor, CPE, SSVC, references, release notes with more details. Need to synthesize. Key points from description: Camaleon CMS versions 2.1.1 through 2.9.1, authenticated remote code execution, users with custom_fields manage permission can execute arbitrary Ruby code via select_eval custom field type. They supply a malicious expression in the field options command parameter, evaluated via instance_eval in ERB view when post edit page is rendered, achieving code execution with web process privileges. CVSS vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. This is a v4 vector. Note the PR:L (low privileges). So authenticated as low privilege? Description says "users with custom_fields manage permission" - that's a specific permission, might be low or high? Typically custom_fields manage is not admin-level, maybe low. PR:L is consistent. AC:L, AV:N, UI:N. Total technical impact. So high CVSS 8.7 (not sure if that's computed score or base? CVSS 4.0 base score with those metrics would be 9.3? Wait, the given score is 8.7, maybe includes some environmental? But vector does not have environmental. Let's compute: AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N -> base score: impact subscore: VC,H=0.56? Actually CVSS 4.0 formula: base score = max( ( (Impact_subscore * Exploitability_subscore)^? No, need to recall. But not necessary, just given score. We'll assess our own vector (both 3.1 and 4.0) based on description. Key: Authentication required (PR:L). Exploitation requires custom_fields manage permission (PR:L). The vulnerability is in how select_eval custom field type is evaluated. This field type was meant for advanced usage, but now they restrict it with a new permission. So prior to 2
Draft post creation in Camaleon CMS through 2.9.2 allows any authenticated low-privileged user to create and overwrite draft posts by bypassing role and permission checks on the admin drafts endpoint. The DraftsController's overridden create and update actions omitted the authorize! calls enforced by the parent PostsController, and used global unscoped post lookups that ignore post type and user ownership, enabling cross-post-type draft manipulation and ownership attribution changes on existing drafts. No CISA KEV listing or public exploit code has been identified; the CVSS 4.0 score of 5.3 (PR:L, VI:L) reflects limited integrity impact with no confidentiality or availability consequence.
Improper authorization in Camaleon CMS 2.9.2 allows any low-privileged authenticated user to overwrite draft content belonging to other users by supplying an arbitrary post_id to the administrator draft autosave endpoint. The application authenticates the requesting user but performs no ownership check, meaning a contributor or editor can silently corrupt unpublished drafts they do not own. No public exploit code has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.
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.
Cross Site Scripting vulnerability in camaleon-cms v.2.7.5 allows remote attacker to execute arbitrary code via the content group name field. Rated medium severity (CVSS 4.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Camaleon CMS is a dynamic and advanced content management system based on Ruby on Rails. Rated high severity (CVSS 7.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Camaleon CMS is a dynamic and advanced content management system based on Ruby on Rails. Rated critical severity (CVSS 9.9), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Camaleon CMS v2.7.0 was discovered to contain a Server-Side Template Injection (SSTI) vulnerability via the formats parameter. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
In Camaleon CMS, versions 2.1.2.0 to 2.6.0, are vulnerable to Server-Side Request Forgery (SSRF) in the media upload feature, which allows admin users to fetch media files from external URLs but. Rated medium severity (CVSS 4.9), this vulnerability is remotely exploitable, low attack complexity.
In Camaleon CMS, versions 2.0.1 to 2.6.0 are vulnerable to an Uncaught Exception. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity.
Camaleon CMS 0.1.7 to 2.6.0 doesn’t terminate the active session of the users, even after the admin changes the user’s password. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
In Camaleon CMS application, versions 0.0.1 to 2.6.0 are vulnerable to stored XSS, that allows an unauthenticated attacker to store malicious scripts in the comments section of the post. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
In the 2.4 version of Camaleon CMS, Stored XSS has been discovered. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
