CVE-2025-12821

Name of the Vulnerable Software and Affected Versions NewsBlogger versions 0.2.5.6 through 0.2.6.1

Description The NewsBlogger WordPress theme is susceptible to Cross-Site Request Forgery due to inadequate nonce validation within the newsblogger install and activate plugin() function. This allows unauthenticated attackers to potentially upload arbitrary files and achieve remote code execution by deceiving a site administrator into performing an action, such as clicking a malicious link. This issue represents a regression of a previous fix.

NewsBlogger version 0.2.5.9: Update to a newer version. NewsBlogger version 0.2.6.0: Update to a newer version. NewsBlogger version 0.2.6.1: Update to a newer version.
