CVE-2025-63068: 
WordPress vulnerability analysis and mitigation

CVE-2025-63068 is a Content Injection (Basic XSS) vulnerability in the Contact Form 7 – Dynamic Text Extension WordPress plugin by sevenspark (developer: AuRise Creative). It allows unauthenticated remote attackers to inject arbitrary content into web pages due to improper neutralization of script-related HTML tags. The vulnerability affects all plugin versions through 5.0.6 (ENISA references ≤ 5.0.3 as the initially reported range). It was reported by researcher Najib Sinjari on August 27, 2025, and published by Patchstack on September 26, 2025, with CVE assignment on December 9, 2025. The CVSS v3.1 base score is 5.3 (Medium) (Patchstack).

The root cause is classified as CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page — Basic XSS). The plugin fails to adequately sanitize or escape user-supplied input before rendering it in web page output, enabling an unauthenticated attacker to inject HTML or script-related tags via crafted input. Exploitation requires no authentication and no user interaction, and operates over the network with low attack complexity. The vulnerability can be abused via attack patterns including XSS through HTTP query strings (CAPEC-32), XSS through HTTP headers (CAPEC-86), and XSS targeting non-script elements (CAPEC-18) (Patchstack).

Successful exploitation allows an attacker to inject arbitrary content — including HTML and potentially script-related tags — into pages and posts of affected WordPress sites. This can be leveraged to embed phishing pages, deface site content, or deliver malicious payloads to site visitors. The CVSS assessment indicates a low confidentiality impact with no direct integrity or availability impact; however, content injection can facilitate secondary attacks such as credential harvesting against end users (Patchstack).

No official patch is currently available for this vulnerability as of the time of publication. The EPSS score is approximately 0.056% (0.000560), indicating a low probability of exploitation in the near term. No in-the-wild exploitation, threat actor attribution, or CISA KEV catalog listing has been reported. Patchstack classifies this as low priority and notes it is unlikely to be exploited, though vulnerabilities of this class are sometimes used in mass-exploit campaigns targeting WordPress sites at scale (Patchstack).

As of the vulnerability's publication date, no official patched version is available from the plugin developer. Patchstack recommends updating the affected plugin as the immediate action; if unable to do so, site owners should consult their hosting provider or web developer. Users of the Patchstack security platform may benefit from virtual patching (vPatching) as a compensating control while awaiting an official fix. Site administrators should also consider temporarily deactivating the plugin if the risk is unacceptable (Patchstack).
