Attack Vectors

Product: Starfish Review Generation & Marketing for WordPress (slug: starfish-reviews)

Vulnerability: CVE-2025-15157 (Severity: High, CVSS 8.8; Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

This issue affects Starfish Review Generation & Marketing for WordPress versions 3.1.19 and earlier. An attacker who already has a low-privileged WordPress account (Subscriber or higher) can exploit a missing permission check in the plugin’s srm_restore_options_defaults function to update WordPress site options they should not be able to change.

From a business-risk perspective, the key takeaway is that the attacker does not need administrator access to start. Any pathway that results in a basic authenticated account (for example, a compromised user password, a shared credential, or an account created through normal business processes) could become an entry point to elevate access and take control of the site.

Security Weakness

CVE-2025-15157 is caused by a missing capability check on the srm_restore_options_defaults function. In practical terms, the plugin does not properly confirm that the requesting user has the appropriate administrative permissions before allowing sensitive configuration changes.

Because WordPress “options” include settings that influence how accounts are created and what roles they receive, the vulnerability can be abused to change critical site behavior. According to the published advisory, attackers can update the default registration role to administrator and enable user registration, allowing them to gain administrative access by registering a new account.

Technical or Business Impacts

Administrative takeover risk: If exploited, this vulnerability can lead to full WordPress administrator access. That creates a direct path to site-wide changes, content manipulation, and potential persistence (e.g., creating additional admin accounts).

Brand and revenue impact: A compromised marketing site can be used to publish unauthorized content, alter landing pages, redirect traffic, or disrupt campaigns. This can damage brand credibility and negatively affect lead generation and conversion performance.

Data and compliance exposure: With administrator-level access, an attacker may be able to access or modify site data and settings in ways that create confidentiality and integrity risks. For regulated organizations, this can trigger compliance reporting requirements, customer notifications, and audit scrutiny.

Operational disruption: The CVSS rating includes high potential impact to availability. A takeover may result in downtime, defacement, or restoration work that consumes internal time and external agency/IR costs.

Remediation note: As of the referenced advisory, there is no known patch available. Organizations should evaluate mitigations based on risk tolerance, which may include disabling/uninstalling Starfish Review Generation & Marketing for WordPress and replacing it with an alternative plugin, along with tightening account controls and monitoring for unauthorized option changes.
