Overview
CVE-2025-27010 refers to a high-risk vulnerability found in the bslthemes Tastyc software, specifically a path traversal issue leading to PHP Local File Inclusion. This vulnerability can allow an attacker to read any file on the system that the web service has access to, potentially leading to unauthorized access and data leakage.
The affected software, Tastyc, is a popular choice for content management and design, providing an attractive target for potential attackers. Any organization or individual using Tastyc versions before 2.5.2 is at risk and should take immediate action to mitigate this vulnerability.

How the Exploit Works
The exploit works by taking advantage of the path traversal vulnerability in Tastyc. An attacker can manipulate file path inputs to navigate beyond the intended directory structure, potentially accessing sensitive files or data. By appending a ‘…/…//’ pattern to a file path, the attacker can access directories that should be inaccessible, and include PHP local files leading to unauthorized data access or even code execution.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited using a simple HTTP request:
GET /file.php?file=.../...//etc/passwd HTTP/1.1
Host: target.example.comIn the above example, the attacker is attempting to access a system’s password file, which could provide information useful in furthering an attack or gaining unauthorized access.
Mitigation
The vulnerability has been fixed in Tastyc version 2.5.2, and it is highly recommended that users update to this version as soon as possible. If immediate patching is not feasible, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by blocking or alerting on suspicious activity. Additionally, the practice of least privilege should be applied to restrict the web service’s access to files and directories.
