CVE-2026-63146

CRITICAL
9.8NVD

Summary

generated automatically from NVD data

Omnispace Agora Project before 26.10.0 is affected by a code injection flaw (CWE-94): during installation, File::updateConfigFile() and DbInstall::dbControl() write unescaped, attacker-controlled values into config.inc.php. A separate SQL injection, made possible by PDO::ATTR_EMULATE_PREPARES allowing stacked queries, lets an attacker re-trigger the installer and insert arbitrary PHP code into that file. This results in unauthenticated remote code execution on the underlying system, and the CVSS v3.1 score is 9.8 (CRITICAL).

NVD description

Omnispace Agora Project before 26.10.0 contains a code injection vulnerability where unescaped, attacker-controlled values are written into the config.inc.php configuration file during installation through File::updateConfigFile() and DbInstall::dbControl(), combined with an SQL injection issue enabled by PDO::ATTR_EMULATE_PREPARES supporting stacked queries. Attackers can exploit the SQL injection to re-trigger the installer and inject arbitrary PHP code into config.inc.php, achieving unauthenticated remote code execution on the underlying system.
