CVE-2026-45545: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in nextcloud security-advisories
Nextcloud is an open source content collaboration platform. From versions 0.7.0 to before 0.7.7, 0.8.0 to before 0.8.10, 0.9.0 to before 0.9.8, and 1.0.0 to before 1.0.4, an authenticated attacker with access to the Tables app may be able to execute arbitrary up to 20 bytes long SQL queries, through a stored injection. With carefully crafted input it is possible to break out of the length limitation. The attacker could use this to extract information from the database, or modify data. This issue has been patched in versions 0.7.7, 0.8.10, 0.9.8, 1.0.4, and 2.0.0.
AI Analysis
Technical Summary
CVE-2026-45545 is a SQL injection vulnerability in Nextcloud's Tables app affecting multiple versions prior to 0.7.7, 0.8.10, 0.9.8, and 1.0.4. Authenticated attackers with low privileges can inject SQL commands up to 20 bytes, with the possibility to circumvent this limit via crafted input, enabling unauthorized data extraction or modification. The issue is fixed in the specified patched versions.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary SQL queries on the database, potentially leading to unauthorized disclosure or alteration of sensitive data. The vulnerability does not impact availability but compromises confidentiality and integrity of the database contents.
Mitigation Recommendations
Upgrading Nextcloud to version 0.7.7, 0.8.10, 0.9.8, 1.0.4, or later (including 2.0.0) fully addresses this vulnerability. Since the vendor advisory indicates these versions contain the fix, applying these official patches is the recommended remediation. No other mitigation guidance is provided or required.
