CVE-2026-63146 is a critical code injection vulnerability in Omnispace Agora Project, published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Affected product: Omnispace Agora Project. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
