Description
baserCMS before 5.3.0 contains a SQL injection vulnerability in BcDatabaseService.php that allows authenticated administrators to inject attacker-controlled table names and configuration values directly into SQL statements across sequence update, CSV export, and table management operations. Attackers can chain a backup restore code injection flaw, where PHP code outside class definitions in schema files executes unconditionally upon loading, to plant malicious table names and trigger error-based SQL injection that retrieves database version, schema contents, and arbitrary data from the PostgreSQL backend.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-76635 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-76635 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-76635. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
