CVE-2026-25233 is a logic error vulnerability classified under CWE-783 (Operator Precedence Logic Error) affecting the PEAR pearweb framework, a PHP-based system for managing reusable components. The vulnerability arises from incorrect operator precedence in the code that checks roadmap roles, specifically allowing users with non-lead maintainer privileges to perform actions reserved for lead maintainers. This flaw enables unauthorized users to create, update, or delete roadmaps, which are critical for project planning and coordination. The vulnerability is remotely exploitable over the network (AV:N), requires low attack complexity (AC:L), and no authentication (AT:N) or user interaction (UI:N). The impact is primarily on the integrity of roadmap data (VI:H), with no direct confidentiality or availability impact. The vulnerability affects all pearweb versions prior to 1.33.0, and a patch was released in version 1.33.0 to correct the logic error. Although no exploits have been reported in the wild, the vulnerability's characteristics make it a significant risk for organizations relying on pearweb for project management and component distribution.

For European organizations, this vulnerability poses a risk to the integrity of project management data within pearweb environments. Unauthorized roadmap modifications can disrupt development timelines, cause miscommunication among teams, and potentially introduce errors in project deliverables. Organizations that rely heavily on PEAR components for PHP development or maintain open-source projects using pearweb are particularly vulnerable. The flaw could be leveraged by insider threats or attackers who gain non-lead maintainer access to escalate their privileges within the project management system. While confidentiality and availability impacts are minimal, the integrity compromise can have cascading effects on software quality and release schedules. Given the widespread use of PHP and open-source frameworks in Europe, especially in countries with strong software development sectors, the vulnerability could affect a broad range of industries including technology, finance, and public sector projects.

European organizations should immediately upgrade all pearweb instances to version 1.33.0 or later to apply the official patch correcting the operator precedence logic error. In environments where immediate upgrading is not feasible, organizations should implement strict access controls to limit roadmap modification privileges exclusively to trusted lead maintainers. Conduct code reviews and audits to detect any unauthorized changes to roadmap data. Employ monitoring and alerting mechanisms to detect unusual modification activities within pearweb. Additionally, organizations should educate maintainers about the vulnerability and enforce the principle of least privilege to reduce the risk of exploitation. Regularly review and update dependency management practices to ensure timely application of security patches in PHP frameworks and components.
