CVE-2026-25773: SQL Injection in Focalboard
// Executive Summary
** 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.
The CVE-2026-25773 vulnerability affects Focalboard and represents a high-severity SQL Injection flaw with real-world consequences for organizations running affected versions.
Data Exfiltration
Attackers can extract sensitive data including user credentials, PII, and confidential records from the database.
Authentication Bypass
Malformed SQL payloads can bypass login forms and grant unauthorized access to privileged accounts.
Data Integrity Loss
Successful exploitation may allow modification or deletion of critical database records.
Follow these steps to determine whether your systems are exposed to CVE-2026-25773:
Detection Checklist
- Identify all instances of Focalboard deployed in your environment (on-premises, cloud, and containerized deployments).
- Check the version of your Focalboard installation — vulnerable versions are indicated in the CVE advisory.
- Audit database query logs for unusual SQL patterns, time-based blind injection attempts, or unexpected data extraction queries.
- Review access logs for anomalous request patterns consistent with SQL Injection exploitation attempts.
- Search for indicators of compromise (IOCs) including unexpected process spawns, unusual network connections, or modified configuration files.
- Run KENSAI's automated vulnerability scanner against your Focalboard deployment to confirm exposure in minutes.
- Check your SIEM/IDS for alerts referencing this CVE or related attack signatures published by threat intelligence vendors.
Immediate Actions Required
- Apply the vendor patch immediately — update Focalboard to the latest patched version as specified in the CVE advisory.
- If an immediate patch is not possible, implement temporary mitigations such as WAF rules to block exploit attempts.
- Review and rotate database credentials — assume they may have been exfiltrated if exploitation occurred.
- Restrict network access to the vulnerable component using firewall rules, limiting exposure to trusted IP ranges only.
- Audit and rotate all credentials (passwords, API keys, tokens) that may have been accessible to an attacker if exploitation occurred.
- Enable comprehensive logging and alerting for the affected component to detect any ongoing exploitation attempts.
- Conduct a post-patch verification scan to confirm the vulnerability has been remediated before returning the system to production.
- Review related systems and dependencies that may be affected by the same vulnerability class.
