Risk Analysis
The True Ranker plugin for WordPress contains a vulnerability that permits unauthorized access to arbitrary files, including critical configuration files like wp-config.php. Despite lacking CVSS and EPSS scores, its presence in CISA's KEV catalog signifies confirmed exploitation, demanding immediate attention.
This vulnerability is actively being exploited in the wild. The flaw is remotely exploitable, as it involves accessing files via a web parameter.
Update the True Ranker plugin to a version beyond 2.2.2. Ensure all WordPress installations are kept up-to-date and restrict file access permissions where possible.
Technical Analysis
CVE-2021-39312 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2021-39312 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
