AI Analysis
Technical Summary
CVE-2026-45545 is a SQL injection vulnerability (CWE-89) affecting Nextcloud's Tables app in multiple versions prior to 0.7.7, 0.8.10, 0.9.8, and 1.0.4. Authenticated attackers with access to the Tables app can inject and execute arbitrary SQL commands limited initially to 20 bytes, but this limitation can be circumvented with crafted input. This flaw enables attackers to read or modify database contents. The issue has been addressed in subsequent patched releases.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary SQL queries on the Nextcloud database via the Tables app, potentially leading to unauthorized data disclosure or data modification. The vulnerability does not impact availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
This vulnerability has been fixed in Nextcloud versions 0.7.7, 0.8.10, 0.9.8, 1.0.4, and 2.0.0. Users should upgrade to one of these patched versions to remediate the issue. No other mitigation or temporary workaround is indicated.
