Craft is a flexible, user-friendly CMS for creating custom digital experiences on the web and beyond. This is an remote code execution (RCE) vulnerability that affects Craft 4 and 5 installs where your security key has already been compromised. Anyone running an unpatched version of Craft with a compromised security key is affected. This vulnerability has been patched in Craft 5.5.8 and 4.13.8. Users who cannot update to a patched version, should rotate their security keys and ensure their privacy to help migitgate the issue.

Craft is a content management system (CMS). The dataUrl function can be exploited if an attacker has write permissions on system notification templates. This function accepts an absolute file path, reads the file's content, and converts it into a Base64-encoded string. By embedding this function within a system notification template, the attacker can exfiltrate the Base64-encoded file content through a triggered system email notification. Once the email is received, the Base64 payload can be decoded, allowing the attacker to read arbitrary files on the server. This is fixed in 5.4.9 and 4.12.8.

Craft is a content management system (CMS). A vulnerability in CraftCMS allows an attacker to bypass local file system validation by utilizing a double file:// scheme (e.g., file://file:////). This enables the attacker to specify sensitive folders as the file system, leading to potential file overwriting through malicious uploads, unauthorized access to sensitive files, and, under certain conditions, remote code execution (RCE) via Server-Side Template Injection (SSTI) payloads. Note that this will only work if you have an authenticated administrator account with allowAdminChanges enabled. This is fixed in 5.4.6 and 4.12.5.

Craft is a content management system (CMS). Prior to 4.12.2 and 5.4.3, Craft is missing normalizePath in the function FileHelper::absolutePath could lead to Remote Code Execution on the server via twig SSTI. This is a sequel to CVE-2023-40035. This vulnerability is fixed in 4.12.2 and 5.4.3.

An issue was discovered in the Feed Me plugin 4.6.1 for Craft CMS. It allows remote attackers to cause a denial of service (DoS) via crafted strings to Feed-Me Name and Feed-Me URL fields, due to saving a feed using an Asset element type with no volume selected. NOTE: this is not a report about code provided by the Craft CMS product; it is only a report about the Feed Me plugin. NOTE: a third-party report states that commit b5d6ede51848349bd91bc95fec288b6793f15e28 has "nothing to do with security."

Craft is a content management system. This is a potential moderate impact, low complexity privilege escalation vulnerability in Craft starting in 3.x prior to 3.9.6 and 4.x prior to 4.4.16 with certain user permissions setups. This has been fixed in Craft 4.4.16 and Craft 3.9.6. Users should ensure they are running at least those versions.
