CVE-2025-28969 is a high-severity SQL Injection vulnerability (CWE-89) found in the cybio Gallery Widget, specifically affecting versions up to 1.2.1. SQL Injection vulnerabilities occur when user-supplied input is improperly neutralized before being included in SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the Gallery Widget fails to properly sanitize special elements used in SQL commands, enabling an attacker with at least low-level privileges (PR:L) to remotely exploit the vulnerability without requiring user interaction (UI:N). The vulnerability has a CVSS 3.1 base score of 8.5, indicating a high impact primarily on confidentiality (C:H), with limited impact on availability (A:L) and no impact on integrity (I:N). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. Exploitation requires network access (AV:N) and low attack complexity (AC:L). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to its potential to expose sensitive data from the backend database. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability affects web applications using the cybio Gallery Widget, which is likely integrated into websites or platforms that display image galleries or media content.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive information stored in databases accessed by the Gallery Widget, such as user data, internal content metadata, or configuration details. The high confidentiality impact means attackers could extract sensitive records, potentially violating GDPR and other data protection regulations, leading to legal and financial repercussions. The limited availability impact suggests some disruption to service might occur, but data integrity is not directly threatened. Organizations relying on the affected widget for public-facing websites or internal portals are at risk of data breaches and reputational damage. The vulnerability’s exploitation without user interaction and over the network increases the risk of automated attacks or exploitation by remote adversaries. European companies in sectors such as media, e-commerce, education, and government that use cybio Gallery Widget could be particularly vulnerable, especially if they have not applied mitigations or workarounds.

Since no official patches are currently available, European organizations should immediately audit their web applications to identify the use of cybio Gallery Widget versions up to 1.2.1. Temporary mitigations include implementing Web Application Firewall (WAF) rules to detect and block SQL Injection payloads targeting the widget’s endpoints. Input validation and sanitization should be enforced at the application level, ensuring that all user inputs are properly escaped or parameterized before database queries. Organizations should also restrict database user privileges associated with the widget to the minimum necessary, limiting the potential impact of exploitation. Monitoring and logging of database queries and web requests can help detect suspicious activity early. Once patches become available, prompt application of updates is critical. Additionally, organizations should review their incident response plans to handle potential data breaches resulting from this vulnerability.
