CVE-2026-25773: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Mattermost Focalboard
** UNSUPPORTED WHEN ASSIGNED ** Focalboard version 8.0 fails to sanitize category IDs before incorporating them into dynamic SQL statements when reordering categories. An attacker can inject a malicious SQL payload into the category id field, which is stored in the database and later executed unsanitized when the category reorder API processes the stored value. This Second-Order SQL Injection (Time-Based Blind) allows an authenticated attacker to exfiltrate sensitive data including password hashes of other users. NOTE: Focalboard as a standalone product is not maintained and no fix will be issued.
AI Analysis
Technical Summary
Mattermost Focalboard version 8.0 contains a second-order SQL Injection vulnerability (CWE-89) due to improper sanitization of category IDs used in dynamic SQL statements during category reorder operations. An attacker with authentication can inject malicious SQL into the category id field, which is stored in the database and executed later without sanitization by the category reorder API. This time-based blind SQL injection can be exploited to extract sensitive information such as password hashes. The vulnerability has a CVSS 3.1 base score of 8.1, indicating high severity. No patch or remediation is available as the standalone Focalboard product is no longer maintained.
Potential Impact
An authenticated attacker can exploit this vulnerability to perform second-order time-based blind SQL injection, potentially exfiltrating sensitive data including password hashes of other users. This compromises the confidentiality and integrity of the affected system's data. Availability is not impacted. No known exploits are reported in the wild.
Mitigation Recommendations
No official fix or patch is available because the standalone Focalboard product is no longer maintained. Users should consider discontinuing use of the affected version or migrating to alternative supported solutions. Monitor vendor communications for any changes in support status or mitigation guidance.
