Published: Thu Jun 26 2025 (06/26/2025, 01:44:38 UTC)
Source: CVE Database V5
Vendor/Project: ickata
Product: Image Editor by Pixo

Description

The Image Editor by Pixo plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘download’ parameter in all versions up to, and including, 2.3.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

CVE-2025-5588 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Image Editor by Pixo plugin for WordPress, developed by ickata. This vulnerability exists in all versions up to and including 2.3.6 due to improper neutralization of input during web page generation, specifically via the 'download' parameter. The root cause is insufficient input sanitization and output escaping, which allows an authenticated attacker with Contributor-level access or higher to inject arbitrary malicious scripts into pages. These scripts execute in the context of any user who views the compromised page, potentially leading to session hijacking, privilege escalation, or unauthorized actions within the WordPress environment. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), scope changed (S:C), and low impact on confidentiality and integrity (C:L/I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no official patches have been published as of the date of analysis. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation leading to XSS. Since the attack requires authenticated access at Contributor level or above, it limits exploitation to insiders or compromised accounts, but the scope is significant because WordPress is widely used, and this plugin is popular for image editing functionality. The vulnerability’s scope is changed, meaning the impact extends beyond the vulnerable component, potentially affecting the entire WordPress site and its users. The attack does not require user interaction, increasing the risk of automated exploitation once an attacker has sufficient privileges.

Potential Impact

For European organizations, this vulnerability poses a moderate risk primarily to websites and web applications running WordPress with the Image Editor by Pixo plugin installed. Exploitation could lead to unauthorized script execution, enabling attackers to steal session tokens, deface websites, or perform actions on behalf of legitimate users. This can result in reputational damage, data leakage, and potential regulatory non-compliance under GDPR if personal data is compromised. Organizations relying on WordPress for customer-facing portals, intranets, or e-commerce platforms are particularly at risk. Since the vulnerability requires authenticated access at Contributor level or above, insider threats or compromised accounts are the main vectors. However, given the widespread use of WordPress in Europe, including government, education, and private sectors, the potential impact is broad. The changed scope of the vulnerability means that the entire site’s integrity can be compromised, affecting confidentiality and integrity of data. Although availability is not directly impacted, the indirect effects such as site defacement or loss of user trust can disrupt business operations. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits rapidly once the vulnerability is public.

Mitigation Recommendations

1. Immediate mitigation should include restricting Contributor-level access to trusted users only and auditing existing user roles to minimize privilege creep. 2. Implement Web Application Firewall (WAF) rules specifically targeting suspicious payloads in the 'download' parameter to block potential XSS attempts. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected sites. 4. Monitor logs for unusual activity related to the 'download' parameter or unexpected script injections. 5. Since no official patch is currently available, consider temporarily disabling or removing the Image Editor by Pixo plugin if feasible until a secure version is released. 6. Educate site administrators about the risks of granting Contributor or higher privileges and enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of account compromise. 7. Regularly back up website data and configurations to enable quick restoration in case of successful exploitation. 8. Engage with the plugin vendor or community to track patch releases and apply updates promptly once available.
