Concrete CMS 9 before 9.5.3 did not escape SQL LIKE wildcard characters in the keyword search filters used by the file manager, file folders, and page list, allowing an authenticated user with editor-level or higher privileges to submit a crafted search containing many single-character wildcards. Because the keyword input was placed into the LIKE clause without neutralizing its wildcard metacharacters, a short request could force the database to evaluate every row and perform a full-table scan, and repeated or wildcard-dense searches could sustain elevated database CPU and I/O, degrading responsiveness for other users on large installations. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.1 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N. Thanks noivan for reporting.
