CVE-2025-67520: 
WordPress vulnerability analysis and mitigation

CVE-2025-67520 is a SQL Injection vulnerability in the Tiny Solutions Media Library Tools WordPress plugin, affecting all versions up to and including 1.6.15. The flaw allows unauthenticated, network-based attackers to inject arbitrary SQL commands into the application, potentially compromising the underlying database. It was reported by researcher "daroo" on November 11, 2025, and publicly disclosed by Patchstack on December 9–11, 2025. NVD assigns a CVSS v3.1 base score of 9.8 (Critical), while Patchstack's WordPress-specific scoring rates it at 7.6 (Patchstack).

The vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), meaning user-supplied input is incorporated into database queries without adequate sanitization or parameterization (Patchstack). The attack vector is network-based with low complexity, requires no authentication, and no user interaction — making it exploitable remotely by any unauthenticated attacker. The required privilege level noted by Patchstack is "Author/Developer," suggesting certain injection points may be accessible to lower-privileged authenticated users as well, though the NVD vector indicates no privileges are required. No public proof-of-concept code has been identified at this time.

Successful exploitation could allow an attacker to execute unauthorized SQL queries against the WordPress site's database, enabling theft of sensitive data (including user credentials, personal information, and site configurations), modification or deletion of database contents, and potentially full administrative takeover of the WordPress installation. The high confidentiality, integrity, and availability impact ratings reflect the risk of complete database compromise. Lateral movement within a shared hosting environment or escalation to server-level access via SQL-based techniques (e.g., file read/write operations) is also a concern (Patchstack).

As of the disclosure date, there is no confirmed public proof-of-concept exploit and no evidence of active in-the-wild exploitation (Patchstack). The EPSS score is approximately 0.021% (0.000210), indicating a currently low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack notes that vulnerabilities of this class are commonly used in mass-exploit campaigns targeting WordPress plugins at scale, regardless of site popularity.

The patched version is Media Library Tools 1.7.0, released by Tiny Solutions; all users should update immediately (Patchstack). If an immediate update is not possible, the recommended interim steps are:

• Disable the plugin until it can be updated.
• Deploy a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts.
• Audit the database for unauthorized changes or suspicious entries.
• Review WordPress user accounts for any unauthorized additions or privilege escalations.

Patchstack users can enable auto-update for vulnerable plugins to automate remediation.

Wordfence included CVE-2025-67520 in its weekly WordPress vulnerability report for the period of December 8–14, 2025, highlighting it among notable plugin vulnerabilities (Wordfence). Patchstack, which coordinated the disclosure, classifies the vulnerability as low priority in terms of immediate exploitation risk despite the high CVSS score, noting it is unlikely to be exploited in targeted attacks. No significant broader media coverage or notable researcher commentary beyond these sources has been identified.
