DescriptionCVE.org

Cross-Site Request Forgery (CSRF) vulnerability in Skywarrior Blackfyre blackfyre allows Cross Site Request Forgery.This issue affects Blackfyre: from n/a through <= 2.5.4.

AnalysisAI

Cross-Site Request Forgery (CSRF) vulnerability in Skywarrior Blackfyre theme versions up to 2.5.4 allows unauthenticated remote attackers to perform unauthorized actions on behalf of authenticated users through maliciously crafted requests. The vulnerability requires user interaction (clicking a malicious link) but carries a high integrity impact (CVSS 6.5). Despite a high CVSS score, the extremely low EPSS score (0.01%) suggests minimal real-world exploitation probability at time of analysis.

Technical ContextAI

CSRF vulnerabilities (CWE-352) occur when a web application fails to implement proper anti-CSRF protections such as CSRF tokens or SameSite cookie attributes. In this case, the Skywarrior Blackfyre WordPress theme (CPE: cpe:2.3:a:skywarrior:blackfyre:*:*:*:*:*:*:*:*) lacks adequate defenses against forged cross-site requests. An attacker can craft a malicious webpage or email that, when visited by an authenticated WordPress admin or user, will trigger unwanted state-changing actions (posting content, modifying settings, user creation) without their knowledge or consent. The attack vector is network-based over HTTP/HTTPS, and no special privileges or complex exploitation is required beyond basic web technologies.

RemediationAI

Upgrade Skywarrior Blackfyre to version 2.5.5 or later, which contains the CSRF protection fix. Site administrators should immediately update the theme via the WordPress dashboard (Appearance > Themes > Updates) or manually via the plugin repository. As a temporary workaround pending patching, restrict theme access to trusted administrators only and implement network-level CSRF protections if available.
