CVE-2025-31051: 
WordPress vulnerability analysis and mitigation

CVE-2025-31051 is a Sensitive Data Exposure vulnerability (CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere) affecting the EngoTheme "Plant - Gardening & Houseplants" WordPress Theme. It affects all versions through 1.0.0 and allows unauthenticated remote attackers to retrieve embedded sensitive data. The vulnerability was reported on March 29, 2025, and published by Patchstack on May 16, 2025. It carries a CVSS v3.1 base score of 5.3 (Medium) (Patchstack, Red Hat CVE).

The vulnerability is classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), which maps to the CAPEC-170 (Web Application Fingerprinting) attack pattern. The flaw allows unauthenticated network-based attackers to retrieve sensitive data embedded within the theme — likely hardcoded credentials, API keys, configuration details, or other sensitive system information — without requiring any authentication or user interaction. No official patch has been released as of the publication date, and no detailed technical write-up or PoC code has been publicly disclosed (Patchstack).

Successful exploitation allows an unauthenticated attacker to access sensitive system information embedded in the theme, which could include configuration data, internal paths, or credentials. While the direct impact is limited to confidentiality (no integrity or availability impact), the exposed data could be leveraged to facilitate further attacks against the WordPress installation or underlying infrastructure. The vulnerability is noted as potentially usable in mass-exploit campaigns targeting thousands of WordPress sites regardless of their traffic or popularity (Patchstack).

No known public exploit code or active in-the-wild exploitation has been reported for CVE-2025-31051. The EPSS score is approximately 0.016% (0.000160), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority with unlikely exploitation, though it notes that similar sensitive data exposure vulnerabilities are sometimes used in mass-exploit campaigns (Patchstack).

As of the publication date (May 16, 2025), no official patch is available from the theme developer EngoTheme for versions through 1.0.0. Users are advised to remove or replace the affected theme until a patched version is released. As an interim measure, site administrators should audit their WordPress installation for any sensitive data that may have been exposed, restrict access to the WordPress site where possible, and consider using a Web Application Firewall (WAF) such as Patchstack to virtually patch the vulnerability (Patchstack).

The vulnerability was discovered and credited to Tran Nguyen Bao Khanh of VCI - VNPT Cyber Immunity, and was published by Patchstack as part of their WordPress vulnerability disclosure program. Wordfence included it in their weekly WordPress vulnerability report for May 12–18, 2025 (Wordfence). No significant broader media coverage or notable researcher commentary beyond standard vulnerability database listings has been observed.
